lifetime fluids

"...that's what we're talking about this morning. Lifetime fluids, the biggest cost shifting trick in the automotive history."

oxygen sensor

'Parts cannon' is a way of saying that someone is just guessing which parts to replace on a car instead of figuring out the real problem. It's like throwing parts at the car to see what works.

Motor oil changes are when you take out the old oil from your car's engine and put in new oil. This is important to keep the engine running smoothly and to prevent damage.

Term

fluid sensitive

"I use what the factory calls for on transmissions because a lot of vehicles now are fluid sensitive. That means you've got to put the fluid in that the factory is calling for and especially..."

Term

automatic transmission

"...150,000 kilometers and the transmission's done. The automatic transmission's done."

An automatic transmission is a system in a car that changes gears by itself, so you don't have to do it manually. This makes driving easier, especially in stop-and-go traffic.
