Re: Can overdrive be utilized in any way during a race?
There's a lot of variables for your question. AT or MT?
IMO... I wouldn't go into overdrive unless I was highway racing @ higher speeds... Even then, I'd still want to downshift.

Re: Can overdrive be utilized in any way during a race?
the O/D button on your auto trans does not turn Overdrive on, it turns it off, overdrive is just your 4th gear.
its not a bad idea to turn it off, but it probably wouldn't be shifting into 4th anyway.

Re: Can overdrive be utilized in any way during a race?
if your throttle is wide open it wont shift into overdrive. it only shifts into overdrive when its just cruising at part throttle. as soon as you punch the gas it downshifts into 3rd

Re: Can overdrive be utilized in any way during a race?
OD doesnt matter if you have it on or off. It gives you no sort of extra HP. Its just your fourth gear. If you dont have it on it wont shift to 4th. And if you drive with it off Youll juss lose gas milage(sp?)

Re: Can overdrive be utilized in any way during a race?
I heard that the AT DSM trannys shift at a lower RPM when the OD is activated. HAving never owned a AT DSM though I cant verify this. EIther way, with the gear ratio being taller I cant see any need for that gear when racing unless you are at high speed. IF you arent at redline in third, you dont need 4th
 OF course on the T25 though you tend to be out of steam around 6500 based on my personal experience, but you get the idea.

Re: Can overdrive be utilized in any way during a race?
Yes. You can stay in OD if there is enough torque. My turbo diesel (450 ft-lbs) for example will pull 13,000 gross up a nice hill in OD. But if the motor is lugging turn it off/downshift.
