Swapping in a higher ratio transaxle
Howdy. We're dealing with my '89, 440T4/4T60, with 2.97 gearing according to original specs.
Since I don't have enough money to do the 6 speed manual project, I want to get a good, kinda lower mileage 440T4 to swap in. Does it matter which one I get? I imagine it has to be like 1988-1990, the newer the better if there have been any updates.
Are the axle splines different at all? And, most importantly, can I get one with a higher axle ratio? If I do, will my odometer/speedometer be messed up, or can it be reprogrammed in the memcal? Or can the drive gear be changed? Thanks.
I know that it'* going to give out in time though due to the supercharger and all, but it'll buy me some time. The last one lasted 172k miles
