P1757 on RAM
Governor Pressure Above 3 PSI In Gear At 0 MPH
P1757 on RAM vehicles indicates governor pressure above 3 psi in gear at 0 mph. Au7o has documented this code across 1 RAM model — most commonly on 1500. 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. Typical repair costs on RAM range from $150 to $500, depending on the specific model and root cause.
Common Causes of P1757
- •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

- 42RE/46RE Governor Pressure Solenoid and Sensor Failure — Limp Mode / Wrong-Gear Start1994-2001
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.

What does P1757 mean on 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 specifically, this code is documented across 1 model.
What causes P1757 on RAM vehicles?▼
Common causes on RAM: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P1757 on a RAM?▼
Repair costs on RAM range from $150 to $500, depending on the specific model and root cause.
