2011年9月6日 · My 04 Jeep Liberty Limited 3.7L 140k miles with the 42RLE transmission suddenly tripped the code P0750 and P0700 and went into limp mode (stays in second gear). I changed the trans filter in hopes the shift solenoid was simply dirty. It didn't work.

2011年10月21日 · Has anyone actually fixed this issue? CEL popped up today, Jeep lost power (limp mode) and AZ pulled the code: P0750 Shift Solenoid A Malfunction. Using the search function only pulled up three related threads: 1. This one I'm using as OP never really got an answer and someone replied saying a flash update solved his similar issue.

2017年6月15日 · P0520 Engine Oil Pressure Circuit, this is one that seemed to be on since I bought it, oil level has always been fine, so I just figured bad connection. the generic P0700 transmission code, P0868 Line pressure low, P0740 TCC out of range, P0750 LR solenoid circuit.

2020年2月25日 · Ok so bought a jeep and it has the p0750 code for l/r solenoid. Long story short just replaced the solenoid pack and filter and new fluid. Reset all codes and it still didn't fix it. In limp mode 2nd gear and reverse only. Just checked the wiring for that solenoid from tcm to the connector on transmission and it seems fine.

2015年11月29日 · The FSM has a lengthy series of diagnostics that isolates the fault to the circuit or valve or PCM as P0750 indicates a circuit problem, not necessarily a bad LR solenoid. The shop needs a DTC and transmission simulator to run all the tests, but I dunno which a competent tech would need to run.

2008年2月15日 · p0750 is not an available dtc used on the nag set up. the 4.7L package with a 545rfe trans has a dtc set for p0750 which is LR (low reverse) solenoid ckt. The transmission enters a limp in mode which only allows certain gears to function to protect internals. certain diag trouble codes will enter ctrl module into this mode.

2015年10月22日 · My wife drives the Jeep. She told me that the CEL came on and it's stuck in third gear. I pulled Codes P0700 P0750. She doesn't know if she heard a loud clunk when the CEL came on. When taking off, it's slow because it's stuck in 3rd. She holds the shifter to the left and the shifter light on the dash moves to "D"rive and it rides a little better.

2015年10月23日 · My Jeep has check engine light on OBDI Code P0750 - Transmission Solenoid Malfunction. When I start driving within half a mile it shifts to 4 and stays there, even if I manually try to change the shift it won't work. Acceleration is slow. I went to local repair shop ( top rated in Angie's list in Area) They kept for a and came back with option ;
