P1757 on Dodge by model: symptoms, diagnosis and fix
The electronically-modulated 42RE (behind the V6) and 46RE (behind the V8) automatic transmissions, used 1996-1999, rely on a governor pressure solenoid and a governor pressure sensor mounted on the valve body to control shift timing. Heat and mileage fatigue the sensor and cause the solenoid to stick, producing erratic, harsh, or delayed shifts. A failed sensor commonly forces the transmission into limp mode (locked in a single gear). This is a well-known, relatively inexpensive failure that is often misdiagnosed as a worn-out transmission.
Common Symptoms
- Harsh or delayed 1-2 / 2-3 shifts
- No overdrive (4th gear) engagement
- Erratic shift points
- Transmission stuck in one gear (limp mode)
- High RPM flare before a hard 'slam' shift
How to Fix
Replace the governor pressure solenoid and governor pressure sensor as a set (inside the pan on the valve body) and change fluid and filter. This only fixes shift-quality complaints on an otherwise-healthy unit; if fluid is burnt or the transmission is already slipping mechanically, a rebuild is required.

Frequently asked questions
What does P1757 mean on a Dodge?
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 Dodge it is documented across 1 model: Dakota.
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 Dodge?
Published repair estimates on Dodge range from $150 to $2,500 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.
