can anyone tell me who can reprogram TCM for 3.07 gears
I'm pretty sure you don't need to re-program for a gear swap. Speed sensors aren't in the transmission.
yes you do, if not it will go into limp mode. resetting it with hp tuner will not help if the TCM is not set up for 3.07 gears.
Depends on if its the 5 spd or the 8 spd. The 8 spd uses the wheel sensors so no recal is needed. This info came from a master calibration tech named Johan Mangs.
my car is an 2012 Charger Sxt plus 8 speed, i have change the gears to 3.07 the car goes in limp mode when you drive.the dealership says the TCM is setup for 3.06 only and needs to b recal, my charger was one the first 8 speed.
.06 to .07 shouldn't be an issue. I'm thinking there's something else wrong here.
you can put the stock gears back in and everything is good
