Have a 3.2 and the trans goes into limp home mode. Problem is intermittent. Any ideas would be great.
Codes:
P0750
P0700
P0700

 

You may have already got an answer to your question, but from the chrysler transmission shop manual, the P0700 trouble code only says "The Transmission Control Module has an internal problem and must be replaced"
The P0750 is LR Solenoid Circuit, which lists these possible causes:

related relay dtc's present
Intermittent wiring & connectors conditions
L/r solenoid control circuit open
L/r solenoid control circuit short to ground
L/r solenoid control circuit short to voltage
transmission relay output circuit open
L/r solenoid inoperative
TCM (L/r solenoid circuit)

I'd check the wiring/connectors for loose connections/frayed wires, and hope it's that and not a bad solenoid/internal tranny issue

 

that information about the p700 code and internal tranny computer and has to be replaced is wrong ignore that part of what was posted.
