Holy crap dude. You have the most understandable schematic illustration on the manual gearbox transmission. Now I get it. All the other videos I've watched have failed to explain transmissions in general, and this is finally understandable. I still don't get Overdrive, haha.
why are you praising the explanation if u still dont get it? 'If you cant explain it to a 4 yo child then you probably dont understand it yourself' , A;bert Einstein. PS : I didnt get it either so Ill be looking somewhere else.
I thought automatics became popular in the US in the early 21st century. I had no idea they've been around for 40 years already. Kinda mindblowing considering that most cars produced for the European market are still manual. That's a good thing, of course, just an interesting contrast.
Sir, I have a question regarding driving an automatic transmission car on a 30-kilometer range uphill route. What is the best driving method to use? Should I use the OD (Overdrive) OFF function or gear 2, 1 or L gear? And to assist with engine braking, on downhill, should I use gear 2, 1, or L for the entire 30 kilometers to prevent damage to the transmission? Your answer and explanation would be greatly appreciated
Very good explanation, thank you. 0:31 Almost, if I wanted to be very annoying I could say this isn't a 1992 Pontiac Firebird, but a 1987 - 1990 bodystyle Pontiac Firebird. Same generation as the '92, though. ;)
Overdrive is just the highest gear in the transmission it allows you too go at higher speeds with les RPMs so it be useful on the highway. The cars that had an overdrive button all that was doing when you pressed the button was allowing the the transmission to shift to 4th gear. Most cars now just do it automatically by detecting how fast you are going as long as you have the shifter in D you’ll get overdrive. If you have a manual same thing 5th gear be overdrive
@@hannankhan2507 no problem it’s basically just the highest gear on the transmission that’s it. It’s the gear that matches the engine speed so it be 1 to 1 that’s overdrive. Whatever speeds the engines doing that’s what the output shafts doing to the wheels.
I have a question for you gear heads out there- So, I saved a 1988 Buick Lesabre Hearse from a scrap yard this week. The big girl runs well, is in great shape, and is genuinely fun to drive. I've gotten many smiles from her at work. I didn't want to see a piece of history get destroyed, and it was the first thing I ever bought for myself. I finally got off my lazy ass and became a productive member of society. Anyway, what I wanted to know was if it is safe to keep her in overdrive? It's an automatic transmission, but she doesn't automatically switch to it, I have to manually shift her into that gear. Is that bad for the engine? I don't know much about the mechanics of cars, let alone old ones, and I genuinely want to take care of her. I probably didn't think it through too well when I bought her, but I am proud to know her fate won't be her rusting away.
Overdrive will only work once the vehicle hits the highest gear so if you got a 4 speed 4th gear is overdrive and you’ll probably never hit overdrive unless you do highway driving
