P0751 on Dodge by model: symptoms, diagnosis and fix
The 46RE (V8 gas) and 47RE (diesel) 4-speed automatic transmissions in Ram 1500 trucks are prone to premature failure, particularly the overdrive unit, governor pressure solenoid, and torque converter lockup. These transmissions are based on the venerable A727/A518 Torqueflite design but the electronic overdrive components are the weak link. Transmission slipping, harsh shifts, and stuck-in-gear conditions are common, especially in towing applications. Overheating is the primary cause of failure.
Common Symptoms
- Transmission slipping in overdrive
- Harsh or delayed shifts
- Stuck in 2nd gear (limp mode)
- Transmission overheating under towing
- Torque converter shudder at highway speed

The 47RE (1994-2003) and 48RE (2003-2007) 4-speed automatic transmissions are the weak link in Cummins-powered Ram 2500 trucks. The factory transmissions were not designed to handle the massive torque output of the Cummins diesel, especially when tuned or used for heavy towing. Overdrive clutch pack failure, torque converter lockup issues, and governor pressure solenoid failures are the most common problems. Overheating is the primary killer, particularly during towing in hot weather or hilly terrain.
Common Symptoms
- Transmission slipping under heavy load or towing
- Harsh or flared shifts between gears
- Transmission stuck in limp mode (2nd gear only)
- Transmission overheating during towing
- Delayed engagement from Park to Drive
How to Fix
Confirm the failure with a road test and scan data, then check line pressure, governor pressure operation, fluid condition/burnt odor, and transmission temperature; also inspect the cooler, cooler lines, and verify torque converter clutch lockup function. Minor issues may be repaired with a governor pressure solenoid/transducer, bands adjusted to spec, and a new heavy-duty torque converter, but most towing- or heat-damaged units need a full rebuild with upgraded overdrive clutches, billet or reinforced input components, shift kit/valve body upgrades, and a larger auxiliary transmission cooler. Use ATF+4 only and service the filter and bands after repair; typical costs run about $400-$900 for solenoid/valve body repairs, $900-$1,500 for converter and cooler upgrades, or $3,500-$6,500+ for a properly built heavy-duty rebuild/replace transmission.

The 42LE (1993-1997) and 42RLE (1998-2004) 4-speed automatic transmissions in the Intrepid are prone to premature failure, including solenoid pack issues, torque converter lockup failure, and internal clutch pack wear. The transmission often develops harsh shifting, slipping, and eventually limp mode. The solenoid pack is the most common failure point and is accessible through the oil pan without removing the transmission. Late model 42RLE units are somewhat improved but still problematic.
Common Symptoms
- Harsh or delayed shifting
- Transmission slipping under acceleration
- Stuck in 2nd gear limp mode
- Check engine light with transmission codes
- Shudder during torque converter lockup
How to Fix
Scan the TCM/PCM for transmission-specific codes (common ones point to the solenoid pack, input/output speed sensors, or torque converter clutch performance), then verify fluid condition and line pressure before condemning the unit. If the transmission has harsh shifts, limp mode, or lockup shudder with no major metal debris in the pan, replace the solenoid pack/filter, service the transmission with the correct ATF+4 fluid, and inspect the valve body and wiring; this repair typically runs about $400-$900. If slipping persists, the fluid is burnt, or clutch material/metal is found in the pan, the transmission usually needs a full rebuild or quality remanufactured replacement with updated internal components and torque converter, typically costing $2,000-$3,500 installed.

The 41TE (1st gen) and 42RLE (2nd gen) automatic transmissions in the Stratus suffer from solenoid pack failures that cause harsh shifting, delayed engagement, and limp mode. The solenoid pack contains the shift solenoids, torque converter clutch solenoid, and pressure control solenoid. Electrical connector corrosion is a common contributing factor. The solenoid pack is accessible through the oil pan without removing the transmission, making it a relatively affordable repair compared to a full transmission rebuild.
Common Symptoms
- Harsh or erratic shifting between gears
- Delayed engagement when shifting to Drive or Reverse
- Transmission stuck in limp mode (2nd gear)
- Check engine light with P0700 series codes
- Intermittent shifting issues that worsen when cold

The A518 (renamed 46RH, then 46RE) 4-speed automatic transmission in Ram Vans suffers from overdrive clutch pack failure, particularly under heavy loads or when used for towing. The Van's aerodynamic profile and heavy weight put more stress on the overdrive unit than truck applications. Symptoms include loss of overdrive, harsh 3-4 shift, and transmission overheating. The 46RE (electronic) version also suffers governor pressure solenoid failures causing erratic shifting. Overheating is accelerated in vans due to poor airflow to the transmission cooler.
Common Symptoms
- Loss of overdrive gear
- Harsh or banging 3-4 shift
- Transmission overheating on highway
- Erratic shifting patterns (46RE electronic)
- Transmission stuck in lower gears

The 3-speed A413 (TorqueFlite) and 4-speed A604 (Ultradrive) automatic transmissions in the Shadow are both prone to failure, but the A604 is significantly worse. The A604 was Chrysler's first electronically controlled automatic transmission and suffered from numerous reliability issues including solenoid failures, premature clutch pack wear, and TCM (Transmission Control Module) problems. The A413 is more robust but still develops torque converter and front pump issues at higher mileage. The A604 earned a terrible reputation and was one of the least reliable transmissions of its era.
Common Symptoms
- Harsh or banging shifts
- Transmission slipping under acceleration
- No 2nd or 3rd gear (solenoid failure)
- Limp mode with only one gear available
- Delayed engagement from Park to Drive

Frequently asked questions
What does P0751 mean on a Dodge?
P0751 stands for "Shift Solenoid A Performance/Stuck Off." This code means the transmission control module commanded Shift Solenoid A (sometimes called Shift Solenoid 1) but the transmission did not respond properly, with the solenoid acting as though it is stuck 'off.' Shift solenoids are electrically operated valves that direct hydraulic fluid pressure to engage gears, so when one underperforms the transmission may shift harshly, slip, or fail to change gears at the right time. The computer sets this code when the measured gear ratio or shift behavior does not match the commanded state. It generally indicates a hydraulic or performance issue with the solenoid or the fluid circuit it controls inside the automatic transmission. On Dodge it is documented across 8 models: Ram 1500, Ram 2500, Intrepid, Stratus, Ram Van, Shadow, Charger, Dakota.
What are the most common causes of P0751?
The most common causes of P0751 are: Stuck or failed Shift Solenoid A, Low, dirty, or degraded transmission fluid, Clogged solenoid screen or valve body passages, Sticking or worn valve body components, Wiring or connector problem at the solenoid, Internal transmission mechanical wear, Faulty transmission control module. The specific cause varies by vehicle.
How much does it cost to fix P0751 on a Dodge?
Published repair estimates on Dodge range from $150 to $5,000 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.
