Big B 04 12-08-2007, 12:31 PM he has it on level 3, as of now the truck is completely stock. He just wanted to try the hypertech sinse he pulls a 5th wheel trailer.thanks sp33d 12-08-2007, 02:02 PM Moved to the correct forum. RideRed1 12-10-2007, 10:26 PM Is it slipping between 1st and second or just defueling hard? Is it limping the trans? epb091786 12-10-2007, 11:41 PM If its slipping it would code. The TCM is much smarter than you think. I am sure what you are feeling is the converter being unlocked and their being a bit more power being put through it which makes it feel looser. Bentley | ||
