Hi,
Before I jump right in and send the e90 to get it unlocked. Is there a way with GM techline to keep using the 2WD 8 speed VIN but flash a calibration file for a 4wd 10 speed truck ? I have a 2wd truck here that swapped the powertrain for a 4wd but still running on the original pcm.
More so a gm techline connect question but I figured I could ask here before.
Thanks
