Just a small question:

What is it and when do you use it?

I don't know much about cars so i just wanted to find out.

Type "overdrive" into the search bar above and you'll get more information than you care for.

But I have O/D off when I'm traveling under 50/60 and then turn it on when I get above that. Or if I'm traveling at a constant 40 or above.

 

i leave overdrive on all the time unless i am racing. what overdrive does is when you are on the highway, if you have it on, it makes your engine run at a lower rpm but you still have a fast speed therefore making you waste less gas. it works best on the highway and you can test it yourself, when you get on the highway today, after you get around 60 or 70, hit the overdrive button. you will notice your rpm go alot lower but you still be going that same speed. whats also good about overdrive is that it puts your car in a higher gear (thats why the rpm is so low) so if you want to pass someone, just mash the pedal and your car will downshift like a beast (meaning, since you was in a higher gear = low rpms, its gonna down shift = making your rpms sky rocket) so you can really get some speed on the highway with overdrive on.

 

"overdrive": all that button does is either lets you into 4th gear or not. THAT's it. the term over drive means when the driver ratio of the gear is less than 1:1. That means you can have more than 1 over drive gear technically. In fact, most 5 speed manuals have more than 1 over drive gear, 4th and 5th gear.

It will not allow you to go faster, it will not make you corner better, it will not even shift better.. it just allows you to go into 4th gear if it's "on".

Why do you want it on? better gas mileage and longer tranny life.

Why would you want it off? I donno... but maybe so you can hold 3rd gear a little longer?

When I'm cruising on the highway with overdrive on and want to pass someone, I just mash on the gas instead of turning overdrive off. I tried turning overdrive off and then mash the gas; I didn't feel any difference. The rpms did jump up when I turned overdrive off, but that's about it. Now, I just leave overdrive on all the time. When I want the power to pass someone, I just simply mash on the gas. Simple huh? Automatics...
