Ok to day i change my tcu because i have to shift to drive and than reverse to get the car to go back and i drive it for a a little bit and than it will get stuck in 3rd i can put it to 2 and it will go to 2nd gear and shift 3rd but no O/D. But if i turn it off it will go back fine and the CEL is on what you think. Don't say nutting about 5 speed because i don't have all the parts right now and i really need my car for work right now.
