Hey Scotty, I just bought this truck last month, and a few weeks ago I was driving down the road and saw that my O/D light was blinking. I tried turning the O/D off but nothing would happen. After pulling over and restarting the car, it drove just fine for about 3 miles, then it would pop up again. When I stop at a stop light and let go of the gas pedal usually it'll push me forward, but either it stays still or if Im up a small slope, it'll pull me back. And when I go to step on the gas pedal to move forward, I have to get the rpms high to actually move. After doing some research on google to see if anyone else had this problem, no one gave me a direct answer, they just gave me possibilities. One of them being the Transmission valve body, I ordered it and replaced it a few days ago and after trying it out, it worked better than before! But after driving a few miles down the road the O/D light came up blinking again. Can you please help me out?
