My first and stock transmission kept kicking out of overdrive on its own, then didn't have overdrive. Changed fluid and filter out 3 times and it would work okay for a day or two then quit working. After a while it wouldn't go into gear or anything. I had two codes on light, TCC solenoid, and shift solenoid. Changed both of them worked fine for 4 days then transmission went completely out. Bought a used transmission, has a warranty and after changing transmission those same two codes popped up. After changing the transmission it only had third and second gear. I would have to manually shift from second to drive for me to have second and third. After changing both solenoids in drive i have first but wont shift out. I have first and second if manually shifted. Now i hear a whining noise sometimes coming from transmission and it wont shift into gear right away. I have to rev the truck up then it will violently shift into reverse. Don't know if the ECM is causing this because my truck will stall and has doing it for a while now. I have to wiggle the middle plug in order to start it back. Can my ECM be the culprit?
