2006 Commander 3.7 V6 W5A580 MB NAG1
My jeep has 180000 miles and is on limp mode. 2 shops have diagnosed the vehicle for codes only. Neither has opened anything up. Both tell me the same info:
1. TCC Solenoid Circuit Error
2. 2-3 Shift Solenoid Stuck On
3. Transmission Temp Sensor Code
4. Input Sensor 2 Code
Neither gave me the actual code numbers.
One wants to replace the torque converter and "maybe" will find other issues.
The other wants to replace the TC, the TCC Shift Solenoid, the Valve Body plate, and "machine" the valve body. And then..."maybe" other issues.
I have decided to tackle this project myself. I can get the parts for $560 including a floor jack, user manual, transmission fluid kit, and fluid. If I pull the pan and find shavings, I can get a used complete transmission for $775 with 1 year warranty.
Here are my questions. How can either shop be 100% sure that the TC is bad? Is there a chance that only the TCC Solenoid is bad? It would be a lot easier to replace only that, wouldn't need to drop entire transmission.
Also, regardless of what repair I do...solenoid only, solenoid and valve body plate, solenoid, plate, and TC...assuming the problem is fixed...will the codes reset and get out of limp mode or will I need to take it somewhere for that?
