About this episode

Ron Ananian kicks off with a real shop story about a “simple” brake job derailed by modern electronic parking brakes. The car wouldn’t enter service mode without the right scan tool function and up-to-date software, forcing Ron to chase subscriptions, Wi‑Fi updates, and tool compatibility—turning a routine repair into an IT problem. He argues this software gatekeeping is a major reason costs rise and DIYers get stuck. The show then pivots to listener Q&A: manual transmission fluid choices for a camper-equipped GM, troubleshooting a 1994 Ranger’s headlight/high-beam cutouts, and DIY brake bleeding plus spark plug/timing belt advice for an ’86 Dodge 600 convertible.

Technical Too Afraid to Ask
Part

electronic parking brake

"Danny looks at me and he says, you know what, this is an electronic parking brake. Okay, and he says, and I knew what that meant, and I didn't think I was going to get this answer."

This is the newer kind of parking brake that’s controlled electronically, not by a simple cable. When you work on the car, you may need to follow special steps so the system doesn’t get confused.

Term

scan tool

"So we grab the scan tool we always grab, and we've got a lot of options... And I'm thinking to myself, wait, this is a modern scan tool... But it won't put this car in service mode."

A scan tool is the device a mechanic plugs into the car to talk to its computer. It can pull up information and sometimes run special repair commands.

Term

software is not current update required

"...we had the choice of Hey, you can try this, but it said your software is not current update required."

Modern scan tools often require up-to-date software to support newer vehicle functions and module commands. If the tool’s software isn’t current, it may not be able to access features like EPB service mode even if the hardware is capable.

Term

updates

"And we're downloading updates and we're waiting for the progress bar to kind of move along..."

Updates are new versions of the software the shop uses. They can be necessary so the tool understands the car correctly and can run the right repair steps.

Term

caliper

"There was a. Time when the biggest problem doing breaks was a rusty bolt, maybe a stuck caliper, something like that."

The caliper is the part that squeezes the brake pads against the rotor. If it gets stuck, the brakes can drag or wear out faster.

Term

rusty bolt

"Time when the biggest problem doing breaks was a rusty bolt, maybe a stuck caliper..."

A rusty bolt is a common older-school brake service problem: seized fasteners can make pad/rotor or caliper removal difficult. It’s the kind of issue that can often be solved with physical tools and proper penetrating/technique.

Concept

download the software

"Of course, I've got to tell you as a shop owner, when you're doing one for the first time and you have to download the software that morning, you don't want the guinea pig to be the car that has to go in two hours."

Sometimes the mechanic has to install the right software before the repair can proceed. Doing that for the first time can take extra time and cause delays.

Term

transmission making oil

"Then I had trouble with the transmission making oil. So I bought a rebuild transmission, and then when they pulled it out..."

“Making oil” in this context likely means the transmission was leaking or producing oil-related mess—commonly from worn seals, gaskets, or internal wear. Oil leaks can be misdiagnosed as internal transmission failure, so identifying the leak source matters before rebuilding.

Brand

Royal Purple

"[769.0s] I had troubles with the two of them, and I bought another one from another company. And my question is [775.1s] royal purple? Can I say the name? [777.5s] Sure? [778.5s] I used that for two hundred miles on the other transmission and it ran goood. But with the squeal, then"

Royal Purple is a company that makes specialty oils for cars. People use it in transmissions and gearboxes to try to improve shifting and reduce noise.

Brand

Red Line

"[784.9s] I hear different things. Vabbling is better, ABS oil is better, [788.4s] red line is better. I'm not sure what's the proper [793.3s] oil to put in? And liquid Molly makes. Liquid Molly"

Red Line makes performance oils for cars. In this conversation, it’s one of the oil brands being considered to improve how the transmission shifts.

Brand

Liquid Molly

"[793.3s] oil to put in? And liquid Molly makes. Liquid Molly [798.9s] makes an MOS two additive for gears, Okay, that the product to put in. [805.2s] So what I remember about these trucks, Frank, was you know the five speed was available two ways."

Liqui Moly is a company that makes aftermarket oils and additives. Here, they’re talking about using a Liqui Moly gear additive to help the transmission work better.

Term

GM synchromesh

"[824.7s] No, no creeper gear right, So five speed with no creeper took GM synchromesh right right, which is you know, that's the that's their GM manual transfluid eighty eight ninety zero three thirty three if I recall the part number correctly. [840.4s] It's been a while since I looked it up, but I like that fluid. I've literally taken vehicles that are [848.2s] you know, seventy five ninety waight gear oil, and their hard to shift, and they're stiff to shift."

GM Synchromesh is a special oil for manual transmissions. It’s meant to help the gears match speed inside the gearbox so shifting is smoother.

Term

manual transfluid

"[824.7s] No, no creeper gear right, So five speed with no creeper took GM synchromesh right right, which is you know, that's the that's their GM manual transfluid eighty eight ninety zero three thirty three if I recall the part number correctly. [840.4s] It's been a while since I looked it up, but I like that fluid."

Manual transmissions use a special fluid, not the same oil as the engine. Using the right kind can make shifting smoother and reduce grinding or stiffness.

Concept

trial and error

"[878.5s] You know, when I did the [878.5s] hot rod, because we're all trial and error to some degree, right, the five speed in the hot rod is supposed to have automatic transfluid in it. Yeah, I know that took [889.4s] me a while to get used to too. But you know,"

They’re saying that finding the best oil sometimes takes experimenting. Different trucks and driving conditions can respond differently, so you may need to try the right fluid to see what works.

Concept

hot rod

"[878.5s] You know, when I did the [878.5s] hot rod, because we're all trial and error to some degree, right, the five speed in the hot rod is supposed to have automatic transfluid in it. Yeah, I know that took [889.4s] me a while to get used to too. But you know, [892.0s] supposed to have automatic transfluent in it. But guess what's [894.4s] in it? GM synchromesh And it works great. And it's"

A hot rod is a car that’s been modified for performance or personal preference. They’re using their hot rod story to show that sometimes the usual rules about fluids don’t always apply.

Term

additive

"I have no problem with the Royal Purple stuff, and I have I have no problem with the additive. Royal Purple makes some great product."

Oil additives are extra chemicals mixed into oil (or added separately) to improve properties like detergency, anti-wear protection, friction reduction, or seal conditioning. Whether an additive is appropriate depends on the oil’s existing formulation and the vehicle’s requirements.

Term

pull the trans

"If if you've got ready access to Royal Purple, that you know, if you had to pull the trans in six months, you could go get more Royal Purple from wherever. Then you know, Royal Purple is the fluid."

They mean taking the transmission out of the car to fix or service it. Since that’s a big job, you want to make sure you can get the right fluids afterward.

Term

high beams

"If I put on my high beams for any period of time, it seems that my my lights, my head lights will go off. They'll blink off and on, off and on."

High beams are the brightest headlights setting. If they make the lights flicker or go out, something in the electrical system is likely failing when more power is demanded.

Term

circuit drawing

"with a built in clamp on it that I could measure current and look to see do I have what am I pulling? What's the circuit drawing? There's a circuit"

A circuit drawing is like a map of the truck’s wiring. It shows how power gets from the battery to the headlights, so you can test the right part instead of guessing.

Term

fuse look burnt

"Does the fuse look burnt? And that's something simple you can do with no tools, right, ok, just just look at the spade terminals."

If a fuse is blown, you can often see it looks burnt or damaged. That’s a quick clue that the circuit isn’t getting power.

Term

spade terminals

"just just look at the spade terminals. Do they look beat Do they look beat up? [1294.4s] Do they look ugly?"

Those are the metal contact points that the fuse plugs into. If they’re dirty, corroded, or loose, power can fail intermittently.

Concept

headlight circuit

"I don't think it's going to be a power feed into the headlight switch, because if it was a power or a feed problem. You'd be telling me the parking lights are going out and the rest of the lights are going out. [1325.2s] If it's only losing headlights, it's something just on that circuit by itself."

Your headlights run on their own wiring circuit. If only the headlights stop working (but other lights still work), the problem is probably in the headlight wiring or parts tied to that circuit.

Concept

wiring diagram

"But of course I'm going to also tell you find a wiring diagram, find a fuse panel. Maybe the owner's Manu'll have that information."

A wiring diagram is like a map of the car’s electrical system. It shows what connects to what, so you can follow the path to the headlights instead of guessing.

Concept

leave the truck running

"And the fact that you can if you can duplicate it if you leave the truck running. [1422.2s] truck running in the driveway, idling with the high beams on, after twenty minutes, did the headlights go out?"

Running the truck with the lights on helps test problems that only show up after things warm up. If the headlights go out after a while, that’s a big clue about what’s failing.

Term

cruise control

"And that's that's you're talking about the cruise control. Right, that's I'm talking about the cruise. But I would also want to look at a wiring diagram."

Cruise control is the system that keeps your car at a set speed. If it stops working, it can be caused by something in the control switches, wiring, or power supply.

Term

common splice

"Sometimes you find a common splice between two different circuits, and all of a sudden, you fix that splice in the headlights work, and the cruise control works"

A common splice is a shared connection where wires for different functions meet. If that connection is bad, more than one thing can stop working.

Brand

Champion

"I'd like a champion in that. I'd put a champion in that. Yeah, champion plugs back back in the day. That was probably factory."

Champion is a company that makes spark plugs. The idea here is to use a plug brand/type that matches what the car originally used or what’s known to work well.

Concept

front wheel drive

"...because it's. A front wheel drive, small square body."

Front-wheel drive means the front wheels do the work of moving the car. It’s a common setup on many older compact cars.

Term

suction gun

"So what's what you're going to [1857.7s] do is get yourself a suction gun, just some sort of you know, and and Advance Auto Parts will have that."

A suction gun is a tool that sucks fluid out. The idea is to remove the old brake fluid from the reservoir so you can put in new fluid.

Term

brake fluid

"You want to extract [1865.9s] all the brake fluid out of the master, okay, and pour in fresh fluid."

Brake fluid is what makes your brake pedal push the brakes. If it gets old or dirty, the brakes can feel worse, so replacing it helps.

Term

brake pedal

"So so you're you're stroking that brake pedal eight to ten times all right. I mean, if you want to, if you want to put somebody in the car and you can watch the fluid come out."

You press the brake pedal to make the brake system move fluid. Pressing it repeatedly helps push out old fluid and air so the brakes work properly.

Term

bleeding

"So you know, doing this with somebody just to stroke the pedal usually is easier on you... After every bleed... How's the pedal feels the same? Good? Move on? Doesn't feel good? You've got air stop and rebleed it."

Bleeding is the process of removing air from a hydraulic brake system. If air remains, the pedal can feel soft or spongy, so the procedure includes re-bleeding when the pedal doesn’t feel right.

Term

air

"How's the pedal feels the same? Good? Move on? Doesn't feel good? You've got air stop and rebleed it."

Air in the brake lines makes the pedal feel soft because air compresses. If the pedal doesn’t feel right, you need to bleed the brakes again.
