Hello

I had some problems with tranny: sometimes it drive in LIMP mode (no 1st and 4th gears), and on diagnostics I had 743, 748 and 753 fault codes. I bought following parts:

- Overdrive solenoid assembly
- Pressure sensor transducer
- Governor solenoid
- Output speed sensor
- Filter

And I replaced it, also changed fluid. But I had again same fault codes and again Jeep sometimes goes in LIMP mode.

What to do people? Is there maybe something like computer restart needed? I think it isnt in LIMP mode when I put transmission in N and then start the engine. But I only THINK, not sure...

Clean the connection on your computer. I had the same problems and after doing all this i ended up changing the trans and problem was still there...Come down to it the connections on the computer were really dirty so i cleaned them up and reset the car and everything is good now....
