P0751 on Chrysler
Shift Solenoid A Performance/Stuck Off
P0751 on Chrysler vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 4 Chrysler models — most commonly on 300, 300M, LHS. 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. Typical repair costs on Chrysler range from $5 to $8,000, depending on the specific model and root cause.
Common Causes of P0751
- •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
P0751 on Chrysler by Model
Chrysler 300(1 issue)
- Shifter Clip Failure - Vehicle Stuck in Park2005-2010
A small plastic clip in the shifter mechanism breaks, causing the vehicle to become stuck in Park. Known design flaw in the first-generation LX platform vehicles. The clip is inexpensive but causes a completely disabled vehicle when it fails. Emergency brake override button near shifter can bypass the issue temporarily.
Chrysler 300M(1 issue)
- 42LE Automatic Transmission Failure1999-2004
The 42LE 4-speed automatic transmission in the 300M is prone to premature failure, including solenoid pack issues, torque converter clutch failure, and internal clutch pack wear. The high torque output of the 3.5L V6 stresses the transmission beyond its design limits. Harsh shifting, slipping, and limp mode are common symptoms. The transmission is shared with the Intrepid, Concorde, and LHS, and the failure patterns are identical across all platforms. The solenoid pack and connector are the most common failure points.
Chrysler LHS(1 issue)
- 42LE Automatic Transmission Failure1994-2001
The 42LE 4-speed automatic transmission in the LHS shares the same failure patterns as the Intrepid, Concorde, and 300M. Solenoid pack failures, torque converter clutch issues, and internal clutch pack wear lead to harsh shifting, slipping, and limp mode. The LHS's heavy curb weight and 3.5L V6 torque output stress the transmission. The solenoid pack and transmission connector are the most common failure points and can be serviced without removing the transmission.
Chrysler Pacifica(1 issue)
- Hybrid Transmission Wiring Harness Short (PHEV)2017-2023
Internal transmission wiring connectors in PHEV models can short circuit, causing unexpected engine shutdown while driving. The low-voltage wiring harness within the transmission develops shorts, causing the gas engine to shut down and the vehicle to go into limp mode or lose motive power entirely. Recall 03A / NHTSA 23V010 issued.

What does P0751 mean on Chrysler?▼
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 Chrysler specifically, this code is documented across 4 models.
What causes P0751 on Chrysler vehicles?▼
Common causes on Chrysler: 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. Specific causes vary by model and year — see the per-model sections below.
