Default WJ 4.0 2003 ECM/PCM and transmission problem

Hello all,

I bought WJ 4.0 2003 year and have some strane problems. Previous owner is replaced ECM/PCM may be with wrong part number ECM
Symptoms:
Check Gauges light
Oil presure not working
Fuel level stay at Full
O/D and transsmision overheating lightst when start the engine.


Transmission is revised yesterday, new ATF, changed some parts.

In Saturday I will take pictures of ECM.

Does anyone have some problems like me with wrong part number ECM?
