About this episode

ZF’s 8HP automatic gets framed as the swap gearbox people keep asking for: fast shifting like dog boxes, but with “the reliability and ease of drivability of an auto.” The discussion digs into why the TurboLamac controller makes swaps practical—torque modelling, bypassing the factory TCU, and CAN/ECU integration—plus how the 8HP’s efficiency and clutch-based behavior can reduce torque-converter downsides. Along the way, the hosts also debate tuning blame, early tuning limitations, and why shift smoothness matters for traction.

ZF 8HP gearbox

"Like, I'm already thinking about putting a ZF in. [27.8s] Welcome to the HPA TuneIn podcast, I'm Andre, your host and in this episode [32.5s] we're joined by Greg from TurboLamac USA. [41.8s] TurboLamac is arguably the go-to controller if you're considering an 8HP gearbox swap"

The ZF 8HP is a modern eight-speed automatic transmission made by ZF. People like it for swaps because it can shift fast for an automatic, but it’s still practical to drive.

Company

TurboLamac USA

"we're joined by Greg from TurboLamac USA. [35.5s] TurboLamac is arguably the go-to controller if you're considering an 8HP gearbox swap [41.8s] into your project vehicle and we wanted to find out why this is such a popular option,"

TurboLamac USA is mentioned as a company that provides the controller used to make an 8-speed automatic swap work. The controller helps the transmission shift correctly in your custom build.

8HP gearbox swap

"TurboLamac is arguably the go-to controller if you're considering an 8HP gearbox swap [41.8s] into your project vehicle and we wanted to find out why this is such a popular option,"

An “8HP gearbox swap” is when you install a ZF 8HP transmission into a car that didn’t originally have it. The hard part is getting it to shift and work correctly with the car’s systems.

Term

controller

"TurboLamac is arguably the go-to controller if you're considering an 8HP gearbox swap [41.8s] into your project vehicle and we wanted to find out why this is such a popular option, [47.8s] why it's necessary in the first place, and also dive a little bit further into what the [52.8s] 8HP gearbox is"

Here, “controller” means the electronics that tell the transmission when and how to shift. Without it, the swapped gearbox may not work correctly or consistently.

Term

aftermarket dog engagement gearbox

"In short, that 8HP gearbox is almost the perfect combination between the speed of shifting with [66.3s] a aftermarket dog engagement gearbox but with the reliability and ease of drivability of"

A dog engagement gearbox is a type of transmission that can shift very quickly using clutches. It’s usually more “race-like” and can be less smooth than an automatic for normal driving.

Term

horsepower

"On top of this, they also don't sap very much horsepower, so again, kind of almost the [88.9s] perfect option."

Horsepower is how much power the engine makes. They’re saying the transmission doesn’t steal much of that power, so more of it reaches the wheels.

Term

aftermarket standalone ECU

"only actually needs [129.2s] a few inputs in order to be able to do the job that it's designed to do. [134.0s] We also talked about the torque modelling inside of the TurboLamac controller and this"

A standalone ECU is an aftermarket computer that controls the engine. The controller discussed here can be set up to work whether you’re using that aftermarket engine computer or the original factory one.

Term

factory ECU

"and interestingly this controller is workable regardless whether you're using an [123.7s] aftermarket standalone ECU or interfacing with a factory ECU and only actually needs [129.2s] a few inputs in order to be able to do the job that it's designed to do."

The factory ECU is the original computer that came with the car to manage the engine. The TurboLamac controller can connect to it and still control the transmission properly.

Term

torque modelling

"We also talked about the torque modelling inside of the TurboLamac controller and this [139.2s] is really critical because the controller or the gearbox really needs to accurately [144.4s] know how much torque the engine is producing so that it can provide the correct shift"

Torque modelling is how the transmission controller figures out how much twisting force the engine is making. That estimate helps it shift at the right time and with the right clutch pressure.

Term

shift pressures

"know how much torque the engine is producing so that it can provide the correct shift [148.1s] pressures and hence the correct or optimal shift strategy. [153.0s] Before we jump into our chat, for those who are new to the TuneIn podcast, High Performance"

Shift pressures are the hydraulic pressures the automatic transmission applies to engage clutches and bands during a gear change. Getting the pressures right is essential for smooth, repeatable shifts and for protecting transmission components.

Term

shift strategy

"pressures and hence the correct or optimal shift strategy. [153.0s] Before we jump into our chat, for those who are new to the TuneIn podcast, High Performance [157.0s] Academy is an online training school."

Shift strategy is how the transmission decides the timing and style of gear changes. If the controller knows the engine’s torque well, it can choose a better shift plan.

Term

head gaskets

"I beat the snout out of that car, you know, multiple head gaskets and clutches but I had it for years and I loved it."

The head gasket is a critical seal inside the engine. If it fails, the engine can overheat or mix fluids, and repairs can be costly.

Term

Subaru symmetrical all-wheel drive

"Whenever it was wet or gravel, that was the best car. I still think in a winter, you know, Subaru symmetrical all-wheel drive is probably one of the best-handling, you know, drivetrains, you know, low sort of gravity."

Subaru’s symmetrical all-wheel drive is their system for sending power to all four wheels in a balanced way. That balance can help the car feel more stable and grippy on slippery roads.

Term

naturally aspirated

"Obviously that engine is legendary. But for handling, I think Subaru was pretty spot on."

Naturally aspirated means the engine doesn’t use a turbo or supercharger. It makes power by breathing air through the intake as the engine spins.

Term

drag racing

"But when I was getting into drag racing and stupidly at the time just showing my lack of knowledge of drag racing, I thought, well, four-wheel drive is obviously going to give"

Drag racing is racing in a straight line to see who accelerates fastest. It’s also hard on the drivetrain, so launch grip and transmission strength matter a lot.

Car

Mitsubishi Lancer Evolution

"...e other. But we were sort of comparing Mitsubishi Lancer Evo III or GC8 Subaru STi and back then the five-spee..."

The Mitsubishi Lancer Evolution is a fast compact car made by Mitsubishi. It’s known for having all-wheel drive, which helps it grip the road. The podcast is comparing different Evo generations and transmission setups for performance.

Car

GC8 Subaru STi

"But we were sort of comparing Mitsubishi Lancer Evo III or GC8 Subaru STi and back then the five-speed gearbox in the GC8, as everyone knows, is basically made of glass"

The GC8 Subaru STi is a classic Impreza STi generation. In this discussion, the key point is that its five-speed transmission is known for being weak compared to what people want to do with it.

Car

Mitsubishi Lancer Evo III

"But we were sort of comparing Mitsubishi Lancer Evo III or GC8 Subaru STi and back then the five-speed gearbox in the GC8, as everyone knows, is basically made of glass"

The Mitsubishi Lancer Evolution III is a turbo rally-style car with all-wheel drive. Here it’s mentioned because people were comparing how tough the transmission is compared to a Subaru.

Term

five-speed gearbox

"then the five-speed gearbox in the GC8, as everyone knows, is basically made of glass whereas I think I ran nine sixes and there was that point where the reliability of the"

A five-speed gearbox is the manual transmission with five gears. The speaker is saying that this specific transmission doesn’t handle abuse or big power increases very well.

Term

air intake

"Back then, you buy a Subaru. There was no tuning. AEM I think just became a company so you could get like an air intake."

An air intake is a part that helps the engine breathe by changing the path of incoming air. The speaker is saying that back then, the main tuning options were things like intakes.

Brand

AEM

"Back then, you buy a Subaru. There was no tuning. AEM I think just became a company so you could get like an air intake."

AEM is a company that sells aftermarket performance parts for cars. In this segment, it’s mentioned as the sort of brand that started offering simple tuning upgrades like an air intake.

Term

Link ECU's

"All these guys are already tuning cars and Evo's and I think early days Link ECU's, [514.5s] maybe it was something before."

An ECU is the car’s computer for the engine. A “Link ECU” is an aftermarket engine computer that lets tuners change how the engine runs, instead of relying on the factory settings.

Term

stand-alones

"There were a limited number of people that were tuning stand-alones. [551.1s] You know, there's a lot of plug and play sort of chips for ECU's and you didn't really"

A standalone engine computer is an aftermarket ECU that takes over engine control. It can be tuned more flexibly, but it’s harder to get right than using the factory computer.

Term

plug and play

"There were a limited number of people that were tuning stand-alones. [551.1s] You know, there's a lot of plug and play sort of chips for ECU's and you didn't really"

“Plug and play” means you install something with little wiring or setup. For tuning, it often makes it easier, but it may not give you the same level of control as a proper tune.

Term

no knock sensors

"Yeah, even back then I remember they would get an email with the tune, you know, God [566.0s] knows from where, no knock sensors, no any real tuning."

Knock sensors are like an engine’s early-warning system for harmful pinging. Without them, the car can’t automatically pull timing to protect the engine if combustion gets too aggressive.

Term

flash it

"They would just get a map, flash it and hope the engine lasts. [573.2s] And it didn't a lot of times, yeah."

To “flash” the ECU means to upload a new tune into the engine computer. If you do it without checking the results, you can accidentally make the engine run in a risky way.

Term

dinos

"Well, the other problem back in that sort of era as well was access to dinos was difficult [582.7s] if not impossible."

“Dinos” means dynos, machines that test a car’s engine under load. Tuners use them to see what power you’re making and to help dial in the tune.

Term

wideband FU ratio meters

"And yeah, the other problem back in that sort of era as well was access to dinos was difficult [582.7s] if not impossible. [584.1s] And even things that we take for granted now like good quality wideband FU ratio meters,"

This tool tells you how much fuel the engine is getting compared to the air. “Wideband” means it’s more precise, which helps you tune safely instead of guessing.

Term

tune

"Yeah. All right, so what direction did you go with this? [607.3s] It sort of sounds like you were interested in the driving aspects. [610.6s] You've sort of alluded to maybe getting involved with the tuning side of things. [614.1s] Bring us up to speed. [616.0s] Actually, no, I actually never got into tuning."

A “tune” is when someone updates the car’s computer settings. That can change how much fuel the engine uses and when it ignites, usually to make the car run better or support upgrades.

Term

plugs

"[649.3s] I understand how car needs to be prepared for tuning from fresh fuel pump, you know, plugs, [655.0s] you know, the basics that a lot of car owners, you know, kind of omit."

“Plugs” are the spark plugs that ignite the fuel in the engine. If they’re worn out or the wrong type, the engine can misfire and the tune may not work as intended.

Term

fuel pump

"[647.0s] You know, I understand how tuning works. [649.3s] I understand how car needs to be prepared for tuning from fresh fuel pump, you know, plugs, [655.0s] you know, the basics that a lot of car owners, you know, kind of omit."

The fuel pump is what sends gas from the tank to the engine. If it can’t deliver enough fuel (or the pressure isn’t right), the engine may not get the right air-fuel mix, which can be dangerous.

Concept

common misconception

"[664.1s] And I always point out that tuner isn't always the guy who messes up your engine. [669.0s] There's a lot of common misconception that, you know, my engine blew up because of a tuner. [674.4s] You know, nine out of 10 times, it's, you know, you got bad fuel, you got lost fuel pressure. [678.5s] People don't understand that."

They’re saying people often blame the tuner when an engine breaks. But the point is that the real cause is frequently something else—like bad fuel or problems with how fuel is getting to the engine.

Term

fuel pressure

"[664.1s] And I always point out that tuner isn't always the guy who messes up your engine. [669.0s] There's a lot of common misconception that, you know, my engine blew up because of a tuner. [674.4s] You know, nine out of 10 times, it's, you know, you got bad fuel, you got lost fuel pressure."

Fuel pressure is how strongly the fuel system pushes gas to the engine. If it’s too low, the engine may run short on fuel, which can lead to problems—especially after a tune.

Term

sequential dog box

"and the Holy Grail was always a sequential dog box. [850.3s] And you know, I would still say that driving around in a car fitted with a sequential dog box [856.2s] makes you feel pretty cool."

A sequential dog box is a motorsport-style gearbox that uses “dog” clutches and a sequential shift pattern (you move through gears in order). It’s built for fast, hard shifts and strong engagement, but it tends to be loud and less forgiving than street-focused gearboxes.

Term

straight cut gears

"Real quick. [862.6s] Real quick. [863.8s] So yeah, the two problems with a motorsport styled dog box is they're noisy. [868.6s] Straight cut gears typically, they're very noisy, the clunks on the shifts."

Straight cut gears are gears with teeth cut parallel to the gear’s axis, unlike helical gears. They can be stronger and efficient for racing applications, but they’re typically much louder, which is why the host calls out the noise.

Term

automatic gearbox conversions

"So then if we thought about automatic gearbox conversions into something that maybe originally had a manual gearbox and it would have been a hard no."

This means putting an automatic transmission into a car that was originally built with a manual. It’s not just “bolt it in”—the car’s parts and computer systems have to match the automatic setup.

Term

slow shifts

"the heavy, big torque converter, slow shifts, not a lot to really kinda get excited if you're a car guy or a car girl."

“Slow shifts” means the transmission takes a noticeable moment to change gears. When it happens during acceleration, the car can feel less punchy and less in sync with your right foot.

Car

8HP

"8HP though seems to have really changed or addressed at least a lot of those aspects. So what is it about the 8HP that makes it such a special gearbox?"

“8HP” is ZF’s eight-speed automatic transmission. The idea is that it shifts and works more efficiently than older automatics, so it can feel more responsive.

Company

ZF

"Well, first of all, ZF or ZF, however you wanna call it, obviously it's a very well known huge corporation that's been around for 100 years."

ZF is a big German company that makes car parts, especially transmission technology. Here, the point is that they’ve been doing it for a long time, so their designs tend to be well engineered.

Term

Euro emission standards

"So these gearboxes are more efficient in a road car application, whether you're in Europe with your Euro emission standards and in the States."

Euro emission standards are rules in Europe that limit how much pollution cars can produce. They can force manufacturers to make cars (including transmissions) more efficient and cleaner.

Term

miles per gallon

"So these gearboxes are more efficient in a road car application, whether you're in Europe with your Euro emission standards and in the States. You know, this is where they save miles per gallon."

Miles per gallon (MPG) tells you how efficiently a car uses fuel. Higher MPG means you go farther on the same amount of gas.

Term

drivetrain

"but a lot of that comes from the drivetrain. So you make a more efficient gearbox."

The drivetrain is everything that sends power from the engine to the wheels. In this discussion, it includes the transmission and how efficiently it moves power along.

Term

billets

"With basic tools, we have customers, there's companies selling kits to make these gearboxes even stronger. There's billets, baskets, there's, you know, Dutson makes a kit."

“Billets” are upgraded metal parts made from a solid piece of material. In transmissions, billet parts are often used to make components stronger so they can survive more power.

Term

stronger clutches and stronger plates

"There's plenty of companies that make stronger clutches and stronger plates. So even though it's a very sophisticated gearbox, it's very user friendly."

Inside an automatic, clutches and friction plates work together to transfer power when the transmission shifts. Upgrading them helps the transmission handle more force without slipping or burning.

Term

OEM application

"I think when they rate these gearboxes, they need to take an account that this is going to work in different parts of the world and that it's going to last you, you know, four or 500,000 miles. With that said, it's, you know, this is why we concentrated on 8 HP ZF. It's got a very good track record. In OEM application, it doesn't really go bad unless you, you know, unless you really try to burn clutches."

“OEM application” means how the car manufacturer intended the transmission to be used from the factory. The host is saying it tends to last in normal use unless you push it too hard.

Term

torque converter slip

"So you've been talking about efficiency and it sort of comes back to what I was saying earlier with the traditional automatic transmission. We get some torque converter slip and basically it's going to, between that and just literally spinning the gearbox the way it works internally,"

A torque converter uses fluid to transfer power, and sometimes the parts inside don’t rotate at exactly the same speed. That “slip” wastes some energy as heat, so the car can be less efficient.

Term

flex plate

"So you've still got quite a large, heavy torque converter that's going to be bolted to the back of your crankshaft or your flex plate. And the gearbox itself, I am going to assume here is still going to be heavier physically than a comparable manual transmission?"

A flex plate is a metal plate attached to the engine that the automatic transmission’s torque converter mounts to. It’s part of how the engine and transmission connect on many automatics.

Term

nine liters of fluid

"Yeah, correct. And it takes almost nine liters of fluid. Converter is heavy."

Automatic transmissions need a lot of fluid to work correctly. Mentioning “almost nine liters” is basically saying it holds a big amount of transmission fluid, which can influence weight and how the system is packaged.

Term

eliminate torque converter

"So since we're talking in a converter side, there's actually an option that you can eliminate torque converter. Lots of our road racing customers develop the adapter that just sends the oil through."

Some racing setups can remove the torque converter and instead route oil directly so the transmission still has what it needs to function. The goal is usually to reduce wasted energy and improve efficiency.

Term

clutch packs

"These gearboxes have internal clutches, several clutch packs. Some are used as brakes, some are used as clutches."

Inside an automatic transmission, a clutch pack is a set of friction plates that can grab or release to control how power flows. Think of it like multiple “clutch switches” working inside the gearbox. In this case, some packs can also act like brakes inside the transmission.

Term

multi-disc wet clutch pack

"It's a multi-disc wet clutch pack like a motorcycle. Yeah. We can do burnouts."

This is a clutch made from multiple friction plates, and it works while bathed in transmission fluid. The fluid helps keep it cool and can make it handle repeated hard use better. The host says this design is part of why the gearbox can do things like burnouts.

Term

burnouts

"We can do burnouts. That's how drifters, you know, drifters use it."

A burnout is when you spin the tires on purpose to heat them up and break traction. The host mentions it to show that this transmission setup can handle hard, aggressive driving. It’s a common thing drifters and performance drivers try to do.

Car

8HP70

"He's got a 2JZ BMW with an 8HP70 that he clutch kicked 56 gear on like a 275 tire and they're still happily taking that."

The ZF 8HP70 is a modern eight-speed automatic transmission. Here it’s being used in a drift car, and the point is that it can be made to launch and behave in a more “clutch-like” way for aggressive driving. The host is using it as proof it can handle that kind of abuse.

Term

slip the converter

"But the downside is you have to drive it like a manual. You can no longer slip the converter."

In an automatic, “slip” means the engine and transmission aren’t perfectly matched in speed. That helps smooth things out, but it can also create heat.

Term

drive by wire clutch

"So you have to have a third pedal. It's a drive by wire clutch. Just think exactly like drive by wire throttle."

A drive-by-wire clutch means the clutch isn’t controlled by a direct mechanical connection. Instead, sensors and computers tell an actuator how much to engage the clutch.

Person

Lucas

"Yeah, so that's Lucas. Lucas is the genius in Poland. We touched on the question how did this all become."

Lucas is the person the hosts credit with the idea and with explaining it to ZF engineers. They describe him as a key contributor behind the concept.

Term

solenoid

"So he started thinking they developed a very crude system to kind of bang the gears. And I mean, it's not that difficult to figure out which combination of solenoid gives you what gear. But then they found out that it needs a lot more finesse."

A solenoid is an electrically controlled valve. In an automatic transmission, it helps route fluid to make the transmission engage different gears. The better the control of the solenoids, the smoother and more reliable the shifting.

Concept

eight-hp swap scene

"And the last, you know, maybe four years, it just blew up. The whole eight-hp swap scene exploded."

An “8HP swap” refers to converting a car to use a ZF 8-speed automatic transmission (the “8HP” naming is common in enthusiast circles). The “swap scene” is the community and aftermarket ecosystem that develops wiring, control integration, and supporting hardware/software to make the transmission work in non-stock applications. The speaker says this community grew rapidly once the swap became more viable.

Term

reflashing

"This package of courses covers everything from tuning and reflashing, petrol, and diesel engines, [1570.2s] through to motorsport wiring, engine building, fabrication, design, car setup, and plenty more."

Reflashing means changing the software in your car’s computer. Tuners do it to make the car run and shift differently than it did from the factory.

Term

motorsport wiring

"This package of courses covers everything from tuning and reflashing, petrol, and diesel engines, [1570.2s] through to motorsport wiring, engine building, fabrication, design, car setup, and plenty more."

Motorsport wiring is the special wiring work done for race cars or serious builds. It’s about making sure sensors and engine electronics are connected correctly and reliably.

Term

WinOLS

"[1594.6s] Want to define maps or tune with WinOLS, curious about CANBUS devices, [1599.6s] or how CAD can help make your dream build a reality?"

WinOLS is a computer program tuners use to edit the car’s calibration data. It helps them change the settings that control how the engine behaves.

Term

CANBUS devices

"[1594.6s] Want to define maps or tune with WinOLS, curious about CANBUS devices, [1599.6s] or how CAD can help make your dream build a reality?"

CAN bus is the car’s internal messaging system—different computers in the car use it to communicate. CAN bus devices are tools that connect to that system to read data or help with integration for tuning or swaps.

Term

drive-by-wire throttle

"especially on the modern car where you have drive-by-wire throttle, we can do blips, cuts,"

Drive-by-wire means pressing the gas doesn’t move a cable mechanically. It sends electronic signals, and the computer controls the throttle.

Term

blips

"especially on the modern car where you have drive-by-wire throttle, we can do blips, cuts,"

In this context, blips are quick, controlled increases in engine speed (often via throttle/ECU command) to help the drivetrain transition smoothly during shifting. They’re commonly used to reduce driveline shock and improve shift feel, especially when coordinating with an automatic transmission controller.

Term

cuts

"we can do blips, cuts, we can very well integrate with pretty much all major ECUs."

A cut is a short moment where the engine’s pull is reduced. Tuners use it to help the transmission shift more cleanly and quickly.

Car

Mark V Supra

"in the drag world, in the States, we have probably 10 cars, like for example, Mark V Supra, B58, every single team that switches to our controller improves their times."

The Mark V Supra is the newer Toyota Supra. The host is saying their transmission controller helps it perform better and shift more consistently.

Term

can communication

"I don't care if it's a Mopar HP 70 or 90, or if it's a BMW gearbox, our controller is the same, we just change the can communication to talk to the car differently."

CAN communication is how different computer modules in a modern car exchange information. If you’re changing transmission control, you have to make sure the new controller sends and receives the right messages.

Term

Haltech World Cup finals

"Did I tell you we do rally cars? But look up, this new record happened at the Haltech World Cup finals in fall of last year."

The Haltech World Cup finals is a racing event where teams compete using performance electronics. They mention it because a record was set there.

Term

transmission mount

"there are kind of off the shelf [1905.3s] conversion kits available to make that part easy. You know, make up a transmission mount [1911.2s] and then probably a tail shaft as well."

A transmission mount is what holds the gearbox in place under the car. When you swap parts, you may need a custom mount so the transmission lines up properly and doesn’t shake.

Term

tail shaft

"make up a transmission mount [1911.2s] and then probably a tail shaft as well. So you've got the thing physically fitted,"

A tail shaft is part of the driveshaft that carries power from the transmission toward the rear differential or final drive. Swaps often need the right length so everything lines up.

Company

Turbulamic

"So this is where Turbulamic comes in [1940.7s] fixing this now broken communication path so you can actually run the transmission. [1945.6s] So you've mentioned that you need to remove the factory TCU."

Turbulamic is mentioned as the company providing a solution for transmission swaps. The idea is to fix the electronics so the gearbox can still operate after you change engines or computers.

Term

torque limiters

"So advantages is we're not worrying about torque limiters, you know, factory safeties. [1970.3s] The biggest one in my opinion, well a lot of people maybe not find that important,"

Torque limiters are built-in “don’t exceed this power” rules. They help keep the gearbox and drivetrain from being overloaded.

Term

ZF intellectual property

"we're not infringing on ZF intellectual property. [1978.5s] We're as far as they're concerned, we're the only company that ZF as a company is called with"

The speaker is talking about ZF’s proprietary software. Their point is that they don’t change or copy ZF’s code, unlike some other approaches.

Term

Ken Gateways

"Our competition is typically based on the Ken Gateways and a modified factory software. [1994.2s] So as far as ZF is concerned, that is a big no-no"

A gateway is a device that helps different car computers “talk” to each other. Here it’s described as a common approach competitors use when doing transmission/ECU swaps.

Term

Mechatronics unit

"The downside is you've got to pull the Mechatronics unit out of the gearbox, [2028.2s] which is super simple, couple torque screws and we physically open it"

The mechatronics unit is the transmission’s “brains and valves” in one package. It helps the car decide when to shift and physically directs fluid to make the gears change.

Term

transbreak

"We can do proper transbreak, we have full control of the gearbox. [2065.3s] We're not relying on factory software anyhow."

A transbreak is a racing mode that keeps the car from moving while the engine revs up for launch. When you release it, the car can launch quickly and consistently.

Term

adaptations

"We do some things in a similar fashion like adaptations, for example. [2073.8s] But other than that, we're 100% responsible for every function of the gearbox."

Adaptations are learned calibration values the transmission uses to compensate for wear and changing conditions. They help the controller match commanded clutch/valve behavior to what the transmission actually does over time.

Term

CAN modules

"We talk to shifters, we talk to the CAN modules, we talk to the ECUs. [2082.5s] A lot more development on our end compared to a simple CAN gateway, like a piggyback."

CAN modules are parts of the car that communicate over a shared network. They let the transmission talk to other computers like the engine ECU.

Term

CAN gateway

"A lot more development on our end compared to a simple CAN gateway, like a piggyback. [2087.6s] I call them piggyback because that's all they are."

A CAN gateway is a device that helps the car’s computers share information. In tuning, it can be used to tweak what one computer sends to another without taking over everything.

Term

piggyback

"I call them piggyback because that's all they are. [2089.2s] So from a sort of an end user perspective, is this a DIY installation"

Here, “piggyback” means a small add-on that works alongside the factory transmission computer. Instead of taking over completely, it usually just tweaks or intercepts certain signals.

Term

oil pan

"You drop the oil pan, you drop the mechatronics, you open the low enclosure, [2111.3s] you sever the low wire connections, you put the board solder in."

The oil pan is the reservoir at the bottom of the transmission that holds transmission fluid. Accessing it is often required for internal work like removing the mechatronics unit or servicing valve/solenoid components.

Term

potting it with the epoxy

"Then we have an option of either potting it with the epoxy [2130.8s] or we have the low covers that we put over the enclosure."

Potting means filling an electronics box with a special hard resin (epoxy). It helps protect the electronics from water and bumps so they don’t fail.

Term

Motec

"Just purely because we talk to everything from Motec to Link to Haltec to, you know,"

Motec is a brand of aftermarket car computer used for tuning. People use it to control and adjust how the engine runs.

Term

"And even if there's an obscure ECU made in Lithuania, as long as we get a can data, [2215.0s] you know, typically it's can standard and we just add that to our support list."

CAN data is how different computers in the car communicate with each other. Instead of each module working alone, they send messages over a shared network.

Term

TPS

"We typically at very minimum need three things from the engine. [2223.4s] RPM, map sensor and TPS."

TPS means the throttle position sensor. It tells the car how much you’re asking for with the gas pedal, so the ECU can estimate torque and help the transmission shift smoothly.

Term

map sensor

"We typically at very minimum need three things from the engine. [2223.4s] RPM, map sensor and TPS."

A MAP sensor measures how much air pressure is in the engine’s intake. That helps the car estimate how hard the engine is working so it can manage torque and shifting.

Term

RPM

"We typically at very minimum need three things from the engine. [2223.4s] RPM, map sensor and TPS."

RPM tells you how fast the engine is spinning. The transmission control uses it to time shifts and match engine output to what the gearbox needs.

Car

BMW M3

"If we're on a factory, you know, BMW M3 that's tuned on a factory DME that only [2286.8s] reports to certain number of torque and then the rest is just, you know,"

The BMW M3 is a performance BMW that many people tune. Here it’s mentioned as an example of a car where the factory engine computer (DME) only reports torque accurately up to certain limits.

Term

DME

"None of the data coming from a DME is accurate because they're all cheating, [2307.8s] you know, to stop the ECU from protecting the engine."

DME is BMW’s engine computer. It controls things like fuel and timing, and it can also show numbers like torque—but those numbers may be influenced by the car’s safety/protection strategies.

Term

throttle position

"So you're on a Haltech or a Link and you said you need throttle position, [2328.9s] manifold absolute pressure and engine RPM."

Throttle position tells the computer how open the throttle is. More open throttle usually means more air and fuel, so it’s used to estimate how much torque the engine is making.

Term

manifold absolute pressure

"So you're on a Haltech or a Link and you said you need throttle position, [2328.9s] manifold absolute pressure and engine RPM."

Manifold absolute pressure is a sensor reading of how much pressure the engine is pulling in through the intake. Higher pressure generally means the engine is under more load, which helps the ECU estimate torque.

Term

internal torque model

"So what's the process of the internal torque model that you're making? [2358.3s] Yeah, we have torque tables that we can adjust and make sure that we're reading correctly."

An internal torque model is the tuning software’s way of guessing how much torque the engine is making. If that estimate is wrong, a torque limiter can behave poorly.

Term

torque tables

"Yeah, we have torque tables that we can adjust and make sure that we're reading correctly. [2364.7s] But there's definitely ways of adjusting that whether we're, you know,"

Torque tables are calibration maps inside the ECU/software that define how much torque the system expects or targets at different operating conditions. Tuning them helps align the software’s torque model with what the engine is actually producing.

Term

cam communication

"So we want to make sure there's no errors, cam communication is good, shifters connected, and then the torque settings need to be adjusted"

Cam communication is the car computer getting correct timing information from the camshaft sensors. If that signal is wrong or missing, the car can throw error codes and run poorly.

Term

torque settings

"and then the torque settings need to be adjusted to make sure that, depending what we're talking to, that we have the accurate readings because like you said, that's absolutely crucial."

Torque settings are the tune’s “target” for how much pulling force the car should make. If they’re wrong, the car can feel off and the readings the tuner relies on may not match reality.

Term

OEM reflashes

"You can look at the OEM reflashes we had back in the day versus a standalone. Obviously standalone is going to give you more power, but it's going to be more time consuming to set up."

An OEM reflash means rewriting the car’s factory computer software. It can be easier than using a separate aftermarket controller because you’re starting from the original setup.

Term

clutch pressure

"Yeah, so basically we are always monitoring clutch pressure, shift times, whether there's any flares, and the software will adjust the clutch pressures..."

Clutch pressure is how hard the transmission squeezes its internal clutches using fluid pressure. Changing that pressure changes how quickly and smoothly the transmission shifts.

Term

flares

"Yeah, so basically we are always monitoring clutch pressure, shift times, whether there's any flares, and the software will adjust the clutch pressures..."

A flare is when the engine momentarily revs up during a shift before the transmission fully locks into the next gear. It can make shifts feel delayed or a bit jerky.

Term

shift quality

"But we always kind of monitor the shift and how it's happening in the shift quality. And that process never really stops..."

Shift quality is how “nice” the gear change feels—smooth, timely, and not jerky. The transmission keeps checking how the shift went and tweaks its settings to improve it.

Term

oil temperature

"There's too many variables starting from your battery voltage to oil temperature,"

Oil temperature matters because the transmission fluid changes thickness when it’s cold versus hot. The transmission adjusts its shifting to account for that so it behaves consistently.

Concept

adaptation process

"Obviously, you've just mentioned that the adaptation process is ongoing. [2636.6s] But in terms of your first shift, as you said, might be a little bit clunky."

The adaptation process is the car’s way of learning how the transmission responds. After setup or tuning, the first shifts may feel a little rough until the car figures out the right settings.

Concept

shift clunky

"But in terms of your first shift, as you said, might be a little bit clunky. [2640.3s] How long does it sort of take before it's essentially driving like it?"

“Clunky” first shifts typically refer to rough or delayed engagement during the initial moments after startup or after a tune/adjustment. In automatic transmissions, this often happens while the control system is still settling shift timing and pressure targets.

Car

Volkswagen Eos

"...es. Most of my customers, including the Mike from EOS and the guys from Drift HQ, when I went there in ..."

The Volkswagen Eos is a Volkswagen car that’s designed with an open-top style. In the podcast, they mention people connected to an Eos and drifting, which means it’s being used for performance driving. The discussion is about how that car fits into their builds or events.

Term

torque reduction for upshifts

"How about, I'm assuming here you've got the ability to do torque reduction for upshifts and you've also mentioned about throttle blips of downshift."

When an automatic transmission shifts up, the car can briefly reduce engine power. That makes the shift smoother and helps avoid a jolt.

Term

CanStream 2

"So we obviously, all our data is available on a CanStream 2 to your device from program, shift card, request, gear, temperatures, you know, spoke speeds, converter speed, output."

CanStream 2 is a tool that lets you read and stream data from the car’s communication network. It’s used to monitor what the transmission and engine are doing while tuning.

Term

converter speed

"from program, shift card, request, gear, temperatures, you know, spoke speeds, converter speed, output. Everything is available."

Converter speed refers to the rotational speed of the torque converter’s components in an automatic transmission. It’s a key signal for diagnosing shift quality and for controlling how smoothly the transmission couples engine power to the drivetrain.

Brand

Holley

"And with the aftermarket ones, I think the only one that is kind of limited currently is Holley. Holley historically never had a need for a blip."

Holley is a company that makes aftermarket performance parts for cars. Here, they’re being discussed in terms of how well their system can do a quick “throttle blip” for smoother shifting.

Term

analog 0 to 5

"It's a shift flag that's sent over CanBus, or we can send it through an analog 0 to 5 to request that."

Instead of sending a digital message, you can also send a simple voltage signal. The “0 to 5” is the range of that voltage used to trigger a request.

Term

drive modes

"Typically we have, so first of all, we have eight different drive modes on the ECU. ... Each of these modes can be set to either launch control or trans-brake."

Drive modes are selectable ECU configurations that change how the car responds (throttle mapping, shift behavior, and launch/traction strategies). Here, the speaker emphasizes that multiple modes can be assigned to either launch control or trans-brake, and even mapped differently (map 1 vs map 2).

Term

launch control

"Each of these modes can be set to either launch control or trans-brake. ... for launch control, we can send a call message to your ECU so you don't need to dedicate a button or switch for your launch control, for example."

Launch control is an ECU strategy that manages engine and drivetrain behavior to optimize acceleration from a standstill. The speaker describes a procedure where you select a gear and hold, and the system instantly enters launch control mode, with ECU messaging that can eliminate the need for a dedicated launch-control button.

Term

trans-brake

"So trans-brake, as I understand it, you're basically engaging first gear and reverse simultaneously. ... So yeah, we apply a second gear and reverse at the same time, which locks up the gearbox."

A trans-brake is a way to keep an automatic transmission from moving the car while you build power. Then, when you release it, the car launches hard and smoothly.

Term

lock up

"So explain how you get around that with 8HP. ... So first of all 8HP torque converter is, we control the lock up."

Lock-up is when the automatic’s torque converter stops “slipping” and starts transferring power more directly. It helps the car feel more connected and can reduce wasted energy.

Term

nitrous

"In Europe, they're being a little more dangerous so they'll do anti-leg or spray some nitrous. [3023.1s] There's a way of making that barrier kind of get overcome."

Nitrous is a system that adds extra gas to the engine to make more power for a short time. People sometimes use it to help the car feel stronger before the turbo really kicks in.

Term

anti-leg

"In Europe, they're being a little more dangerous so they'll do anti-leg or spray some nitrous. [3023.1s] There's a way of making that barrier kind of get overcome."

“Anti-leg” sounds like a trick people use to reduce a hesitation when the engine is trying to build boost. In this episode it’s mentioned as part of methods to help the car get past a low-RPM “stuck” feeling.

Car

BMW 8HP-70

"Okay, but it is still a consideration. [3042.6s] Yeah, we get a lot of BMW 8HP-70's diesels in the states and those seem to be the ones that cause problems with customers [3052.1s] that they cannot spool up the engine at low RPM."

Here, “BMW 8HP-70” means a BMW that uses the ZF 8-speed automatic called the 8HP-70. The point is that, on diesel versions, the car can feel weak at low engine speeds because it doesn’t build boost/RPM quickly enough.

Term

spooling up

"Yeah, we get a lot of BMW 8HP-70's diesels in the states and those seem to be the ones that cause problems with customers [3052.1s] that they cannot spool up the engine at low RPM."

“Spooling up” means the turbo is building boost by spinning faster. If the car doesn’t get the engine RPM up quickly enough, the turbo can’t make power yet, so it feels slow or unresponsive at low speeds.

Term

adapter

"First of all, make sure you have an adapter for your engine for the gearbox you look into use [3086.8s] because if you have like a Toyota engine and then you're like, [3091.0s] oh, I'm going to fit an Alfa Romeo gearbox because it's $300 on eBay."

An adapter is the part that lets an engine and a transmission physically fit together in a swap. The host’s warning is that the adapter has to be the right one for that exact engine and gearbox combination.

Term

rotating mass

"These gearboxes, not only they're smaller, so they're a little more responsive due to rotating mass, [3126.3s] but they're available and they're cheap."

Rotating mass is the “stuff inside the drivetrain” that has to spin. If there’s less of it, the car can speed up and slow down more quickly, so it feels more responsive.

Term

V8 boxes

"[3170.2s] I'm like, those are V8 boxes. [3172.1s] They're never designed to spin that fast."

“V8 boxes” means transmissions made for V8 engines. They’re built to handle bigger power and twisting forces, but they still have limits—so pushing them to extreme RPM can cause problems.

Term

foot-pounds of torque

"You know, don't put a demon gearbox on a 600 foot-pounds of torque, unless most popular ones are... Again, almost 1000 foot-pounds of torque, massive abuse."

Foot-pounds of torque is a unit of rotational twisting force. The hosts use it to set expectations for how much load a transmission can survive, especially under “massive abuse” like drifting. Their point is that torque level alone isn’t enough—you also need the right transmission internals for repeated shock loads.

Term

small frame gearboxes

"The next, the third limitation is if you're building a drift car, try to stay away from the small frame gearboxes. Not that they cannot take the torque."

“Small frame gearboxes” refers to a transmission/gearbox size class with less internal mass and typically less torque capacity. The hosts recommend avoiding them for drift cars because the planetaries and other internal components become the weak points under repeated high-load abuse. The key idea is matching gearbox size to the harsh duty cycle of drifting.

Term

planetaries

"Not that they cannot take the torque. The planetaries are small and it's usually a weak point."

Planetaries are the planetary gear sets inside an automatic transmission. In this segment, the hosts say the planetaries are small in certain “small frame” gearboxes and are usually the weak point when torque and abuse are extreme. That’s why they steer drift builds toward stronger transmission variants.

Term

drive shaft

"And he finally cracked the case, but we think that was due to a vibration from a drive shaft. They're incredibly strong."

A drive shaft transfers rotational power from the transmission to the differential/axles. The hosts attribute a cracked case to vibration from the drive shaft, highlighting how drivetrain imbalance can create damaging harmonics even when the transmission is “incredibly strong.”

Car

1966 C10

"we've got a project lined up that, in typical HPA fashion, probably isn't going to happen for another three to five years, but still, when we put a twin-turbo 1000 horse LS into a 1966 C10, which model should I be going for on that?"

A 1966 C10 is a Chevrolet C10 pickup from the 1960s, known in the tuning world as a popular platform for swaps and high-power builds. In this segment, it’s the base vehicle for a planned twin-turbo LS project, and the hosts discuss which ZF 8HP variant (70 vs 75) would be the right transmission choice for that kind of torque.

Term

LS

"when we put a twin-turbo 1000 horse LS into a 1966 C10, which model should I be going for on that?"

“LS” refers to the GM LS-family V8 engine platform, which is extremely popular for swaps and high-power builds due to its strong aftermarket support. In this segment, “twin-turbo 1000 horse LS” is used to describe a high-torque engine that demands a transmission built for abuse. The hosts are essentially matching transmission durability to the LS build’s output.

Term

twin-turbo

"but still, when we put a twin-turbo 1000 horse LS into a 1966 C10, which model should I be going for on that?"

Twin-turbo means using two turbochargers instead of one to force more air into the engine. This setup is commonly used to make very high power and torque, which is why it’s relevant to transmission selection in the segment. The hosts mention a “twin-turbo 1000 horse LS” to emphasize the extreme drivetrain loads.

Part

billet baskets

"Sonax makes clutch plates, there's billet baskets, there's billet input shaft. I also want you to have a 70 over 90, 95 that can take a lot more power..."

Billet baskets are aftermarket transmission components machined from billet aluminum/metal rather than cast. The hosts list them alongside other billet parts as upgrades for stronger internal support in high-torque builds. The goal is to reduce flex/weak points and improve durability under repeated abuse.

Part

clutch plates

"Sonax makes clutch plates, there's billet baskets, there's billet input shaft. I also want you to have a 70 over 90, 95 that can take a lot more power..."

Clutch plates are friction components inside an automatic transmission that engage to transfer torque between gear sets. The hosts mention Sonax clutch plates as part of a strategy to handle higher torque and abuse. Upgrading clutch materials can improve heat tolerance and durability under aggressive driving.

Part

billet input shaft

"Sonax makes clutch plates, there's billet baskets, there's billet input shaft. I also want you to have a 70 over 90, 95 that can take a lot more power..."

A billet input shaft is an upgraded transmission input shaft machined from billet material. The hosts include it as part of a package of stronger internal parts for high-torque applications. This kind of upgrade is meant to improve strength and resistance to twisting loads and failures.

Brand

Sonax

"Sonax makes clutch plates, there's billet baskets, there's billet input shaft. I also want you to have a 70 over 90, 95..."

Sonax is mentioned as a supplier of clutch plates for high-torque automatic transmission builds. In this context, it’s part of the aftermarket upgrade path the hosts recommend when pushing beyond the “sweet spot” torque levels. The key point is that transmission durability can be improved with targeted internal parts.

Term

Baja truck

"Again, I rarely see an application for 90, 95 unless you're building like a Baja truck that sees a lot of loads and shocks. Most people don't need it."

A Baja truck is a pickup or off-road truck configured for desert racing and rough terrain, where it experiences repeated impacts, loads, and shocks. The hosts use it as an example of a use case where a higher-capacity transmission variant (90/95) might make sense. The idea is that off-road shock loads can justify extra hardware strength.

Term

sweet spot

"But a 70 or 75 is, I always call it a sweet spot. And here in the States, Dutch charger challenger, they made million of them and kids are crashing them left and right,"

“Sweet spot” here means the most favorable range for a particular setup—likely balancing cost, drivability, and transmission behavior. The speaker frames it as a practical target (a 70 or 75) rather than a strict technical specification. It’s a tuning/selection concept used in performance discussions.

Car

Dodge Challenger

"And here in the States, Dutch charger challenger, they made million of them and kids are crashing them left and right,"

The Dodge Challenger is a popular American muscle car. The hosts bring it up because there are so many of them that wrecks create lots of used parts. That makes it easier to find components secondhand.

Car

Dodge Charger

"But a 70 or 75 is, I always call it a sweet spot. And here in the States, Dutch charger challenger, they made million of them and kids are crashing them left and right,"

The Dodge Charger is a popular American muscle car. The hosts mention it because lots of them exist and many get wrecked, so parts show up in junkyards and online. That affects how easy it is to find used components.

Term

shift cut

"In terms of upshifts under full load, do we require a shift cut or some kind of torque reduction from the engine? Or is there a point above which in terms of the engine's making X amount of torque at that point, if you want to keep the clutches alive, we do need some kind of torque reduction?"

A shift cut is when the car briefly makes a little less power during an automatic gear change. That gives the transmission an easier, gentler moment to swap gears. The goal is to reduce wear and keep the gearbox working well.

Term

ignition box

"We recently had a gentleman that had an older carburetor car but had an ignition box. We were able to achieve that through an ignition box."

An ignition box is an aftermarket gadget that controls how the spark timing works. On older cars that don’t have modern computers, it can still help the engine make less power at the right moment. In this case, it was used to help protect the transmission during shifts.

Term

downshift

"Same goes for blips. Obviously we'll speed up the downshift. It'll just be smoother and nicer on the downshift with a blip, right?"

A downshift is when the car goes into a lower gear. That usually makes the engine rev higher so the car can accelerate or slow down more effectively.

Term

dog engagement style racing gearbox

"In terms of the shift speed or shift time, how does that compare to a conventional manual gearbox, maybe a conventional traditional automatic gearbox and a dog engagement style racing gearbox?"

A dog-box is a race gearbox that locks gears together very directly. It can shift extremely fast, but it’s usually less smooth than a street gearbox.

Term

shift speed

"In terms of the shift speed or shift time, how does that compare to a conventional manual gearbox, maybe a conventional traditional automatic gearbox and a dog engagement style racing gearbox?"

Shift speed is how fast the car changes gears. Quicker isn’t always better if it makes the car lose traction during the change.

Term

load cell

"I don't know how that compares to a dog box with a load cell. You can get those under 100 milliseconds, but there's a lot, I mean, it depends on so many things."

A load cell is a sensor that measures force or load—here, typically driver input (like throttle/brake pressure) or torque demand. In shift control, it helps the transmission predict what the driver is asking for so it can time engagement more precisely.

Term

DCT

"Yeah, so obviously probably sequential is going to be faster. DCT is going to be slightly faster, but we don't like the headaches that sequentials do and DCTs do."

DCT means dual-clutch transmission. It uses two clutches so it can switch gears quickly, often with less delay than a normal automatic.

Concept

fine tuning the engagement

"Correct, we absolutely have a way of fine tuning the engagement. Even for example, for downshift we can make it more aggressive like drifters like it"

This means adjusting how the transmission actually “grabs” the next gear. The goal is to make it feel right and avoid breaking traction while still shifting quickly.

Term

drifters

"Even for example, for downshift we can make it more aggressive like drifters like it because it locks up the rear end and they can initiate the turn,"

Drifters are drivers who intentionally slide the car sideways while keeping control. They often want the drivetrain to behave in a way that helps the rear end break traction and start the slide.

Concept

workaround

"“We don't have a native control for those. We do have a workaround, but we don't have a native control.”"

Here, “workaround” means a temporary or indirect way to make the system work when the ideal direct control isn’t available. It’s basically a substitute solution until a better, more direct control method exists.

Concept

native control

"“We don't have a native control for those. We do have a workaround…”"

“Native control” means the control system can talk to the transmission in the intended, direct way. If it’s not native, the system may need extra tricks or compromises to get the same behavior.

Car

BMW X3M

"...have a native control. And then like your M3, M4, X3M uses the mid-frame 8 HP 76. Those are the latest ..."

The BMW X3 is a luxury SUV. The podcast mentions the X3M and a specific transmission type (“8 HP 76”), which is part of how the car sends power to the wheels. They’re likely discussing drivetrain details that affect performance.

Term

mid-frame

"“like your M3, M4, X3M uses the mid-frame 8 HP 76.”"

“Mid-frame” is describing where the transmission sits in the car’s structure. Different placements can mean different mounting and control details, which matters for fitting or controlling the gearbox.

Term

valve body

"“They completely redesigned the valve body and how it's controlled with the solenoids. …you have to replace the valve body to the second gen.”"

In an automatic transmission, the valve body is like a control unit that directs fluid to the parts that make the transmission shift. If the valve body design changes, the shifts can feel different and may require different control hardware.

Car

Toyota Tundra

"Currently, we're working on can communications for some Toyota platforms for their V6 and V8, like Toyota Tundra. [3676.3s] We have a lot of requests for customers wanting to swap these gearboxes into those vehicles."

They’re talking about the Toyota Tundra because it’s one of the trucks they want to support for transmission swaps. The big challenge is making sure the car’s computer still “recognizes” the transmission after the swap.

Term

CAN sniffer

"So we actually monitor with the OEM car, we put a can sniffer. [3722.2s] Lukas actually has a fancy can network hub of sorts that monitors all the communication."

A CAN sniffer is like an audio recorder for the car’s internal network. It lets you see what messages the factory modules are sending so you can copy that behavior with an aftermarket setup.

Car

BMW M5

"So for example, when you put a turbo-lamic controller in 2025 M5, it acts like a factory car. [3748.4s] We send the same communication from the shifter."

They’re using the BMW M5 as an example of a new, computer-heavy car. Their controller has to mimic the factory signals so the car doesn’t get confused and disable starting or other functions.

Car

Toyota Gr86

"... customers keep asking for it. We're working on a GR86. There's an adapter developed in Sweden by Damiwo..."

The Toyota GR 86 is a sports car designed to be fun to drive. People are asking for it in the context of a specific adapter or setup. The podcast is saying they’re working to make their solution work with the GR86.

Company

Damiworks

"There's an adapter developed in Sweden by Damiworks. [3781.0s] You guys are familiar with Damiworks. [3783.0s] So he's almost done with the F824 and the EGA adapter."

Damiworks is a company that makes a custom adapter part. That adapter helps fit a different gearbox into a car so the swap can work.

Term

turbo kit

"And we had the stock FA20 engine in that with a turbo kit on it. [3816.0s] Had a little Borgwana EFR turbo running on E85, MoTeC control."

A turbo kit is a set of parts that adds a turbo to the engine. The turbo forces more air in, which lets the engine make more power.

Term

FA20 engine

"And we had the stock FA20 engine in that with a turbo kit on it. [3816.0s] Had a little Borgwana EFR turbo running on E85, MoTeC control."

The FA20 is the engine that comes in the original Toyota 86. In this story, they kept the factory engine and added a turbo kit to make more power.

Term

E85

"Had a little Borgwana EFR turbo running on E85, MoTeC control. [3820.5s] And I mean that thing, we limited it to about 380 wheel horsepower."

E85 is a fuel blend with a lot of ethanol in it. It can help a turbo car run more power because it resists knock better than regular gas.

Term

Borgwana EFR turbo

"Had a little Borgwana EFR turbo running on E85, MoTeC control. [3820.5s] And I mean that thing, we limited it to about 380 wheel horsepower."

An EFR turbo is a specific type of turbocharger made by BorgWarner. The point here is that it spooled in a way that made the car feel smooth and predictable.

Term

fourth gear

"The problem with it of course was fourth gear. [3841.8s] And the only way I could actually keep fourth gear alive was to pull all of the boost out of it"

Fourth gear is one of the gears in the transmission. They’re saying that with their turbo setup, fourth gear was the weak point—so they had to change gears to keep things working.

Term

boost

"And the only way I could actually keep fourth gear alive was to pull all of the boost out of it [3846.1s] and fourth which you'd go from third to fourth and it felt like someone had pulled"

Boost is the turbo’s “extra push” that increases how much air the engine gets. In this story, they had to reduce that push in fourth gear to keep the car behaving properly.

Term

short shift

"and fourth which you'd go from third to fourth and it felt like someone had pulled [3850.5s] a couple of coils off it. [3852.9s] And then you'd sort of short shift it straight into fifth"

Short shifting means you shift sooner than usual. They’re doing it to avoid the car’s weak spot in fourth gear and get the power back where it works.

Term

CVT

"[3867.4s] The manual, not the greatest. [3870.2s] The CVT is just atrocious. [3873.0s] And they're slow with those."

CVT means the automatic transmission doesn’t use fixed gears. Instead, it smoothly changes ratios, but some people think it makes the car feel less connected or slower than a normal automatic.

Term

8 speed

"[3870.2s] The CVT is just atrocious. [3873.0s] And they're slow with those. [3874.7s] And I think you know with the 8 speed it would definitely feel a lot more peppy"

An “8 speed” means the car has an automatic transmission with eight different gear ratios. Having more gears can help the engine stay in the right range so the car feels more lively.

Term

supercharger

"[3874.7s] And I think you know with the 8 speed it would definitely feel a lot more peppy [3878.7s] especially if you put a supercharger or a turbo on it. [3881.5s] I've driven one on the, and I remember I was getting on the highway ramp."

A supercharger is a device that forces extra air into the engine. More air helps the engine make more power, especially when you accelerate.

Car

Honda Civic in 1996

"[3886.0s] So I'm going downhill and I'm like... [3889.4s] And I'm like what is this Honda Civic in 1996? [3892.8s] It's just such a great platform but it needs like 100 horsepower."

They’re saying the car feels like a 1996 Honda Civic—basically, it doesn’t feel very quick. It’s a comparison to show they think it needs more power.

Term

turbocharging

"[3918.0s] oh the next generation 86 is going to come out with a turbo or supercharger. [3922.6s] And having gone through turbocharging one and honestly the amount of work [3927.1s] that went into then keeping the temperatures under control,"

Turbocharging means adding a turbo to make the engine produce more power. It usually requires extra cooling/heat control so the engine can handle the added stress.

Term

third generation ZF

"So now the third generation ZF caught up with speeds. [4010.8s] They're simple, they're bulletproof."

They’re talking about a newer version of ZF’s eight-speed automatic. The idea is that the later version shifts faster than earlier ones, without losing the smoothness and reliability people want.

Term

Powerline

"I know here in the States they're coming out with a new eight speed for a rum truck. [4037.0s] That's, they call it Powerline."

“Powerline” sounds like the name for a new transmission ZF is rolling out. The speaker implies it’s built for trucks, where it needs to handle hard work reliably.

"So that opens up a lot of customers in the diesel market because you have all these crazy diesel guys with 4,000 foot pounds of torque."

“Diesel market” just means people who own diesel cars. Diesel engines often make a lot of twisting force, so they look for transmissions that can handle that stress.

Concept

next popular swap

"because you have all these crazy diesel guys with 4,000 foot pounds of torque. So that's gonna be a next popular swap. We already have a million emails from them."

A “swap” means replacing one big part of the car with a different one. The host is saying this kind of transmission change will become popular because it works well with high-torque diesel setups.

Term

shift times

"[4208.6s] You've talked about the shift times being slightly faster still with DCT but now almost comparable. [4214.0s] The other part of that puzzle was the massive torque converter..."

Shift times are how fast the transmission changes gears. Shorter shift times usually mean the car feels more immediate when you accelerate.

Car

X3M

"You don't really feel the torque converter, especially on a modern like a current M car or even like the SUV, [4232.9s] like an X3M or something like that."

The BMW X3M is the sporty, high-performance version of the X3 SUV. The host is saying that in a car like this, the automatic transmission can shift so smoothly you don’t feel it like a typical automatic.

Term

eco mode

"They're even in eco mode. ... I've tested these gearboxes and I would be in eco mode and floor it and switch it to sport."

Eco mode is a driving setting meant to help the car use less fuel. Here, the host is saying the transmission can still shift quickly and feel responsive even in that “economy” setting.

Term

overspeed the gearbox

"We typically, for whatever we have crazy customers, we have to turn off their eighth gear because they can overspeed the gearbox. ... If you have decent amount of power, it will speed."

Overspeeding the gearbox means the transmission is being forced to spin faster than it should. The host is saying they may turn off a high gear to prevent that when someone drives very hard.

Term

diff

"You just got to at some point try to stay on the road because it doesn't have a good diff."

“Diff” is short for differential, a part that helps the wheels turn at different speeds when you’re cornering. If the diff isn’t set up well, the car can feel unpredictable or harder to control.

Car

bone stock E36

"I have a bone stock E36 with the 8HP45 and I went from driving it 200 miles a year to driving it 5,000, 6,000 miles a year."

The BMW E36 is an older 3 Series (from the 1990s) that a lot of people modify. Here, it’s being used as an example of an E36 that’s been upgraded with an 8-speed automatic (8HP45).

Term

S58

"It's just X3M, that drivetrain, the new S58 with the 8HP, absolutely ridiculous."

S58 is BMW’s name for a specific high-performance turbo engine. The point here is that when that engine is matched with the 8-speed automatic (8HP), the car feels extremely quick and fun.

Topic

PRI show

"When I came back from PRI show, we came back to a couple hundred orders. ... It was funny because two years ago at PRI, one ZF guy comes in and I'm like, uh-oh, because I don't know what their stance is."

PRI show is a big trade show for racing and performance parts companies. People go there to meet customers and suppliers and to talk about new products. The speaker is using it as a timeline for when these discussions started.

Term

third gen gearboxes

"Like I mentioned, the support for the third gen gearboxes would be great. That's something we're working on, same with the truck transmissions."

“Third gen gearboxes” means a newer version of the gearbox design than earlier ones. Different generations can require different parts or programming to work correctly. They’re asking for better support for that newer gearbox version.

Term

truck transmissions

"Like I mentioned, the support for the third gen gearboxes would be great. That's something we're working on, same with the truck transmissions. That's the next plan."

Truck transmissions are gearboxes built for heavier vehicles. They often have different strength and cooling needs than passenger-car transmissions. They’re saying they want to expand support to those truck versions too.

Term

PCB installation

"We also have on the board, we're working with ZF to maybe simplify the process of the PCB installation. They might have a product that would eliminate the needs to install the boards."

A PCB is a small electronics board with circuits on it. Here, they’re talking about installing one as part of a transmission-related setup or upgrade. They want to make it easier so you don’t have to install the board yourself.

Concept

IP

"Yeah, you're not infringing on their IP. It was funny because two years ago at PRI, one ZF guy comes in and I'm like, uh-oh, because I don't know what their stance is."

IP means intellectual property—things a company legally owns, like designs or software. If you build a product that interacts with a manufacturer’s system, you have to make sure you’re not copying or violating their legal rights. They’re saying they’re not infringing on ZF’s IP.

Concept

junkyards

"As far as they're concerned, we're just saving, not only we're saving the gearboxes from junkyards, from wrecking yards, but we're also kind of elevating the status of the gearbox to this 2GZ of gearboxes."

A junkyard is where old cars are taken apart for usable parts. They’re saying they’re saving transmissions from those places.

Term

removable bell housing

"There's a version of a Austin Martin gearbox that has a removable bell housing. So that would mean if I could buy 200 gearboxes and then develop a bell housing for 2GZ, for KA, for LS."

A bell housing is the housing between an engine and a transmission that helps align and secure the transmission to the engine. A removable bell housing means that section can be taken off or swapped, which can make it easier to adapt a gearbox to different engine/transmission setups.

Term

contract

"Obviously, we're a relatively small company, so I don't fully know what it takes to sign a contract with ZF for a couple hundred gearboxes."

A contract here just means a formal deal with the supplier about buying parts. They’re saying they’re a small company, so they’re not sure how that process works.

Term

drift car

"We have a trailer. I have a drift car. We have a bunch of cool cars."

A drift car is a car used for drifting—where you steer into a corner and the back end slides sideways on purpose while you keep control.

Term

manual

"They just learned how to drive a manual because everything's automatic in the States. So they go do a little bit of sliding."

A manual is a car where you shift gears yourself using a clutch pedal. It takes practice, especially if you’re used to automatic cars.

Term

sliding

"So they go do a little bit of sliding. You know, we come back home next week."

Here “sliding” means the tires aren’t gripping normally, so the car moves sideways a bit. It’s like the controlled sideways motion you see in drifting.
