I'm new to HP Tuner and was hoping for help with an issue i'm having. I have a 2014 ram 1500 with an 8 speed and every time i write my tune to the ecm and tcm my transmission locks in third gear and will not shift to any other gear other than neutral and reverse still work properly? any help would be great, the issue is fixed by writing in the stock tune but i would love to be able to actually change things in the tuning files haha
