P1757 on RAM: How to Diagnose & Fix
Governor Pressure Above 3 PSI In Gear At 0 MPH

P1757 on RAM by model: symptoms, diagnosis and fix
The electronically-controlled 42RE/46RE automatics regulate shift points with a PWM governor pressure solenoid plus a governor pressure sensor/transducer in the valve body. These parts get contaminated by transmission varnish and wear out. When the sensor feedback no longer matches the commanded pressure, the PCM sets a code and drops the transmission into 'limp' mode — no overdrive, 2nd/3rd-gear start, harsh or no shifts. Extremely common on high-mileage 2nd-gen Rams.
Common Symptoms
- Transmission stuck in limp mode (2nd/3rd gear only)
- No overdrive / no lockup
- Wrong-gear starts
- Harsh or delayed shifts
- Speedometer-related shift errors
How to Fix
Drop the pan and replace the governor pressure solenoid (Mopar 4617210) and the governor pressure sensor/transducer (56028196AD, supersession of 56041403AA); available together as an aftermarket kit (e.g. Hercoo/TransGo). Fresh ATF+4 and a filter at the same time. DIY parts ~$40-$120; shop job $150-$500. Confirms and clears P0748/P1757/P0868 limp-mode codes.

Frequently asked questions
What does P1757 mean on a RAM?
P1757 stands for "Governor Pressure Above 3 PSI In Gear At 0 MPH." Manufacturer-specific (Chrysler, Dodge, Jeep and Ram with RE-series automatic transmissions such as the 42RE, 44RE, 46RE and 47RE). The governor pressure control system regulates the pressure that controls first, second and third gear shifts, and the controller compares requested pressure to the pressure reported by the governor pressure sensor. This code sets when pressure stays above roughly 3 PSI while the vehicle is in gear and stopped, meaning the governor circuit is not bleeding down as it should. Drivers typically report harsh or delayed shifts, starting off in second gear, or the transmission dropping into limp mode. On RAM it is documented across 1 model: 1500.
What are the most common causes of P1757?
The most common causes of P1757 are: Failed governor pressure sensor (a very common failure on RE-series transmissions), Faulty or sticking governor pressure solenoid, Contaminated, burnt, or low transmission fluid, Clogged transmission filter restricting the governor circuit, Damaged wiring or corroded pins at the transmission case connector, Internal valve body wear or a failed transmission control module. The specific cause varies by vehicle.
How much does it cost to fix P1757 on a RAM?
Published repair estimates on RAM range from $150 to $500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
