I was driving back from VA today and left out of the gas station and everything was fine no noises or anything but my 1-2 shift was extremely rough and almost like it was in tow/haul... So i drove on and stopped again shut the truck off and went again and it was ok... Not too sure if its something serious that i need to get looked at it just felt like enough of that harsh shifting could break something. Also when it goes to o/d it shutters in and out of gear or converter lockup... I need help please..

 

no one knows....
