P0751 on Jeep by model: symptoms, diagnosis and fix
The Commander frequently displays "Transmission Over Temp" warnings even when fluid level and condition are normal. The transmission control module (TCM) and powertrain control module (PCM) are prone to failure, causing the vehicle to stall, shift erratically, or enter limp mode. Separately, NHTSA Campaign 08V203000 (Chrysler H19) is a PCM software reflash for engine stalling on 2006 Commanders with the 4.7L V8 built before January 11, 2006 - it is not a transmission or TCM recall. 216 powertrain complaints were filed for the 2006 model year alone.
Common Symptoms
- Transmission Over Temp warning on dash
- Vehicle enters limp mode (3rd gear only)
- Erratic or harsh shifting
- Vehicle stalls while driving
- Transmission slips under load
- Check engine light with transmission codes
How to Fix
Start with a transmission fluid and filter change using ATF+4 (Mopar 68218057AB). Install an auxiliary transmission cooler ($100-200, Hayden 679 or Derale 13502) for sustained relief. Replace the TCM if faulty ($300-500 for module plus programming). Check transmission cooler lines for leaks. If overheating persists, the torque converter may be failing and need replacement ($800-1,500).
Owner tips & cautions
- TipIf the transmission enters limp mode, pull over safely and let it cool for 15-20 minutes before driving again

Frequently asked questions
What does P0751 mean on a Jeep?
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 Jeep it is documented across 1 model: Commander.
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 Jeep?
Published repair estimates on Jeep range from $200 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.
