Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
RAM 1500 · 1994–2001
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.
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.

Dodge Dakota · 1996–1999
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 often misdiagnosed as a worn-out transmission - Mopar reportedly priced the parts high early on because so many were failing.
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?
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.
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?
Repair costs for P1757 range from $150 to $2,500, depending on the vehicle and root cause.
