I have a 03 duramax with the alison tarns. I put an edge on it about 2 years ago and now it is not going into reverse sometimes and when it does go into drive it is like it is starting off in a higher gear. It is showing some bad codes when we plug it into a computer none of the chevy people can figure it out or even want to try has anyone ever had something happen like this????
P.S it is kind of like there is a short some where in the comp.
