Overdrive Button

Recommended Posts

I'm not a car geek, mostly into aesthetic car stuff...When should overdrive be used and when should it be turned off?

Living in Florida.....I never turn OD off. If living where very hilly or mountainous....where I might need to keep RPM up to better climb hills at less than full throttle, would probably turn it off for climbing. Especially if engine is struggling at low RPM and doesn't seem to want to down shift on it's own.

 

May turn OD off to come down a long steep mountain also. If I needed some additional engine braking.

Only turn it off if you're towing a heavy load and it's constantly downshifting to maintain speed or you're descending a long hill or mountain and want to use engine braking to save the friction brakes from heating up.

 

The last time I turned it off was in the mountains spring of last year.

I turn it off to downshift in corners & when I put it in launch mode at a stoplight.

I thought the "L" was launch mode...

 

OP: I turn OD off all the time because I like the way it shifts better than when it's on.

This may be a stupid ? but does the "L" stand for launch or something else?

it definitely does not stand for launch. it is for "Low" as in low gearing

c_bova is correct. It's Low. It provides higher RPM and more engine braking.

Just an additional note RE: "L": if you put it L from a stop and just give it a little bit of gas, you'll never get out of first gear until you open up the throttle. If you give it full throttle and hold it, it will run up near redline and then shift while in L up the gears until it gets to 5th (I believe).

 

Mike, are you smoking those 22s in your "launch mode"? It most certainly will smoke the 18s.

He's smoking something if he thinks OD off gives him a better launch. It doesn't.

You beat me to it. But hey, if it makes him feel better....

I never knew guys thanks for the heads up...actually its not for the initial launch but so the tranny doesnt shift into higher gears during acceleration ;)

While the ODbutton is off and you are decending a hill just touch the breaks and hold the pedal, not enough to engage them, and the trans will downshift. If the speed isnt slowed the trans will downshift another gear. Very handy way to slow in hilly areas without using your breaks.

Depending on the grade of 'descend', you don't even have to touch the 'breaks', it will downshift on its own...calm down akirby...

I took a really deep breath and decided to let it slide. I'm getting soft in my old age.
