Last year I had Trent change my tcm tune to start out in 2 gear when the tow/haul is activated. I want to put it back to were it works normal. I don't know how to do that or what he has done to the tune so could I just find a stock 5 speed tcm tune and load it in the truck to be back to normal? I don't know if he did any change to the tune when we built the trans. What would be my best way of doing this?
