I have the Chrysler manual and it shows me the same picture but its not located there the only that is there is the PCM.

Let me know your VIN # XXXXX I will check what transmission you have.
It is possible that your vehicle does not have a TCM.
Please reply back to this thread.

Thanks,
Your Jeep has a 4.0L engine and a 42RE automatic transmission.
42RE automatic transmissions do not use a TCM, that is why you can't find it .
Let me know if you need more information.

I received a p0740 diagnostic code what would i do to fix this cause i was told that it was the tcm?
P0740 indicates that there is a problem with the Torque Convertor Clutch.
More than likely you have a mechanical issue. You should have it checked by a transmission specialist .
Below is the code description and possible causes:

This code wills set if the Torque Convertor Clutch (TCC) cannot achieve

the desired drop in engine RPM when the TCC solenoid is near the maximum duty cycle.Two trips of three consecutive bad tests are required to set the code.

POSSIBLE CAUSES:

CHECK FOR MISFIRE CODES

INTERMITTENT TCC SOLENOID

CHECK THE TRANS FLUID LEVEL AND CONDITION

INPUT SHAFT SEALS

INTERNAL PROBLEM OR TCC SOLENOID

OIL PUMP/SHAFT/SEALS

TORQUE CONVERTER

VALVE BODY
