P0750 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 42LE (A606) automatic transmission solenoid pack develops electrical failures causing harsh shifts, stuck in gear, or limp mode (locked in 2nd gear). The solenoid pack is an all-in-one unit that must be replaced as an assembly.
Common Symptoms
- Harsh shifting
- Stuck in 2nd gear (limp mode)
- Delayed engagement
- Check engine light with trans codes
How to Fix
Replace the solenoid pack assembly and transmission filter. Flush the transmission fluid. Updated solenoid packs from Mopar address the earlier design weaknesses.

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

Common Symptoms
- Slipping gears
- Harsh shifts
- Transmission stuck in limp mode
- P0750/P0755/P0760/P0765 codes
- Speed limited to 40 mph in limp mode
How to Fix
Install new design 42RLE 10-pin connector (dealer wiring repair). Replace solenoid pack. Verify park pawl recall completed. Use ONLY Mopar ATF+4 (68218058AC).

Frequently asked questions
What does P0750 mean on a Dodge?
P0750 stands for "Shift Solenoid A Malfunction." This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. On Dodge it is documented across 9 models: Ram 1500, Ram 2500, Intrepid, Stratus, Charger, Ram Van, Shadow, Nitro, Dakota.
What are the most common causes of P0750?
The most common causes of P0750 are: Failed or stuck shift solenoid A, Open, shorted, or chafed solenoid wiring, Corroded or loose transmission connector, Low, dirty, or degraded transmission fluid, Clogged solenoid or valve body passages, Internal valve body or hydraulic fault, Faulty transmission control module (TCM). The specific cause varies by vehicle.
How much does it cost to fix P0750 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.
