I was driving my dads truck 2001 gmc 2500 hd duramax with the allison and he has the edge programmer in it. I cranked it up to level four and got on the gas hard, and now the engine light is on and it wont shift out of third gear. It has done this before and all we did was shut the truck off and and let it sit for a bit and it reset itself. However this time it is not resetting itself. What do i do?
