Changed engines, transmission started shifting hard and when you stopped at stop sign it won't down shiftvautamatically. You can shift it manually. After truck get to normal temperature you can shut it off and restart it and shifts perfect as long as truck don't sit for 5 or 6 hour and you have to go through process again. Have checked engine grounds, had shifting selenoid changed, changed ignition switch, changed computer
