Isnt overdrive usually 5th Gear? When cars first came into mass production they only had four gears. It was a hugh break though when they invented a car with 5 gears. The 5th gear was called an over drive gear.

 

yeah i believe overdrive is 5th gear in a manual and 4th gear in an automatic...everytime someone asks me what it is and I tell them they don't believe me cause they think thats too simple of an answer

 

overdrive is when a gear puts out more revs than it takes in. meaning that the ratio is under 1:1 so it "overdrives" the speed of the engine. and i kno wthat top gear in a 5-speed honda is an overdrive, and i think it is in an auto as well. its good for gas mileage.

 

Yeah its the best for mileage.

 

i had a sport mode button in my jaguar, but all that did was shift higher and run richer fuel

 

You didn't know what an overdrive was and you want to build cars? That's weak sauce.

 

everyone has to start somewhere.

 

That's how we all learn, by asking questions. And now he knows all about overdrive.

 

You're weak sauce. I'll bet, rather I'll guarantee that I know more about anything to do with cars than you.
