P0751 on Dodge by model: symptoms, diagnosis and fix
The 42LE (A606) 4-speed automatic transmission used in the Intrepid from 1993 to 2004 is 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. Later 42LE 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 automatic transaxle in the Stratus (and the related 40TE used on some 2003-2006 models) suffers 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 bolts to the outside of the transaxle case and can be replaced 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
How to Fix
Read the stored transmission codes first, then check fluid level and condition, the transmission control relay feed, TCM power and grounds, and the solenoid pack connector for corrosion, since a wiring or power fault can force limp mode with a good pack. If a solenoid circuit or pressure-switch code points to the pack, replace the solenoid/pressure switch assembly as a unit (it is held to the transaxle case by three bolts), then perform the TCM Quick Learn procedure with a scan tool. Internal clutch damage from prolonged driving in limp mode can push the bill toward a rebuild.

The Mercedes-derived W5A580/NAG1 5-speed automatic in V8 Chargers suffers from water intrusion past the transmission oil fill tube/dipstick seal. Water contamination causes TCC to stick/slip, erratic shifting, and eventual internal damage. Separately, 2006-2009 police-package Chargers with a column shifter were recalled (08V583, 20,283 Charger and Magnum vehicles) because the gearshift cable can disengage from its steering-column bracket.
Common Symptoms
- Shudder during light acceleration in 3rd-5th gear
- Torque converter clutch sticking or slipping
- Erratic upshifts and downshifts
- Milky/foamy transmission fluid
How to Fix
Replace dipstick seal to prevent water intrusion. Flush transmission fluid with Mopar ATF+4 (MS-9602), the fluid Chrysler specifies for the NAG1 in these cars. Replace valve body if internal damage present.

Frequently asked questions
What does P0751 mean on a Dodge?
On Dodge, P0751: On the Chrysler PCM in older Dodge rear-wheel-drive trucks with the 46RE/47RE (documented for the 2nd-gen 24-valve Cummins Ram, and reported by owners on 1998 Dakota and 1999 Durango 46RE trucks), P0751 is defined as 'OD OFF SWITCH PRESSED (LO) MORE THAN 5 MINUTES'. It sets if the overdrive switch is held low for 5 minutes or more. Causes are an intermittent or defective O/D off switch, its sense circuit shorted to ground, or the PCM. On these trucks it is not a shift-solenoid performance code.

How much does it cost to fix P0751 on a Dodge?
Published repair estimates on Dodge range from $200 to $4,000 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.
