Sweet!!!!
I got it figured out now. I have a 15-tooth drive speedometer gear and so to go from 2.73's to 3.42's and having 245-50-16's, I need a 41-tooth driven gear in the tranny P/N 25513048, correct?
So all I need to buy and install is P/N 25513048 right?

Go to the hanlon motorsports T5 speedo page and type in your tires size and gear ratio. Then there will be no guess work in choosing the correct gears for a T5. Not sure about an auto trans though.

Wait are you guys saying that If i go from 2.73's to 3.42' the part number to make my speedo accurate is:
15T PN8642620
Or is it:
41T PN 25513048
Or what? I have a 700R4.
Im putting in gears soon and this is somthing i forgot about. does my computer care about the right speedo gear thing?
