Looking to find someone that can program the transmission for the truck or someone that can tell me what to buy to do it.
Truck goes 40 mph while dash says 80 and hits limiter.
Truck has had transmission swapped but can't find anyone to program it. Need a gm tech 2 capable device or a programmer to tell computer what transmission and tire size are apparently really common problem. Tried to find support on website to ask question now I'm here on this forum hoping I can just pay someone to fix it rather than need to buy a programmer.
