I started tuning my truck recently and now it likes to slide into 2nd gear! At WOT it is fine but any 1-2 shift in part throttle it slides into gear. I have a Transgo HD2 shift kit and a TB stall. I dint know if it is something that I tuned or what? I swapped out computers for a spare one I had laying around that was never worked on before and it does the same thing! Any help is appreciated!
