i just did a swap in my 05 silverado from a buiilt 4l65 with 4wd and went to a 4l80 and its only 2wd now. i have hptuners but havent done to much with it and now i need to somehow add the extra vss that the 4l65 didnt have. i have the sensor all wired in but where do i make the changes in the programming for it to recognize the new sensor??
