Tranny not shifting
From a stop, it will shift from 1st to 2nd just fine and then will redline the truck in 2nd and the rpms will vary. Some times you can get it to shift by getting on and off the throttle, does the same thing when trying to go from 3rd to overdrive but even harder to try to get it to shift. The overdrive off light will start to flash. After the truck has this problem and you shut it off and come back to it, reverse is gone, nothing there till you put it into drive and then come back to reverse and its fine. Take off from where you are and the tranny acts perfect, no issues. Somedays you can go the whole day and never have a problem. So this problem comes and goes. Below are the codes I got from the computer. Let me know if theres any other info I can get/tell you to help get an idea of whats wrong.
