I have a 1993 Formula with a Stock 700R4 in it i was wondering what speedo gear i would need to up the rear end gears to 3.73's? it currently has 2.73's?
i do not know the drive gear in the tranny im guessing its stock? what ever the stock drive gear is? any help is appreciated!

I do believe you can get your PCM retuned for the new gears if im not mistaking

Agreed, although the tune could benefit you more than just matching your speedo. I noticed better all around engine performance, better MPG's, and it picked up some horsepower too. I got mine tuned at lt1pcmtuning.com
