Truck is tuned and running amazing, however now I?d like to Unlock a TCM for the truck so we can tune the transmission. My truck currently has a TCM that isn?t supported by HPtuners to be unlocked, I will buy a TCM with a supported service number. My question is, does anyone know which service number TCM I would need to make this work? I know it?s possible but everyone that has done it is keeping secrets lol my truck is a 2023 Silverado, 5.3 with 10 speed 4wd and column shifter. If anyone has any ideas I?m open ears.
