P0751 on Chevrolet
Shift Solenoid A Performance/Stuck Off
P0751 on Chevrolet vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 8 Chevrolet models — most commonly on Blazer, C/K 1500, Camaro. 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 Chevrolet range from $150 to $4,000, 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 Chevrolet by Model
Chevrolet Blazer(1 issue)
- 9-Speed Automatic Transmission Shudder2019-2024
The 2019+ Blazer with the 9-speed automatic transmission (9T50/9T65) develops a shudder during acceleration from a stop, particularly between 1st and 2nd gear. GM bulletin PIP5608J addresses TCC shudder/surge issues. The root cause involves excess lubrication on internal parts contaminating the transmission fluid. Some owners require torque converter or full transmission replacement.
Chevrolet C/K 1500(1 issue)
- 4L60E Automatic Transmission Failure1993-1998
The 4L60E transmission is known for 3-4 clutch pack burnup, sun shell failure, and worn input drum. These trucks were often used for towing which accelerated wear. The transmission develops slipping in 3rd and 4th gears.
Chevrolet Camaro(1 issue)
- 10-Speed Transmission Wheel Lock-Up (10L80)2020-2022
Vehicles equipped with the 10-speed automatic transmission may experience momentary wheel lock-up when shifting from 8th to 5th gear. A transmission control valve is susceptible to premature wear, leading to pressure loss and potential wheel lock-up.
Chevrolet Impala(1 issue)
- 4T65-E Transmission Failure and Hard Shifts2000-2013
The 4T65-E automatic transmission used in the 2000-2013 Impala is one of the most failure-prone GM transmissions. Common failures include the 1-2 accumulator piston cracking (causing harsh 1-2 shift), pressure control solenoid failure (erratic shifts and slipping), and the forward clutch hub cracking (complete loss of forward gears). The 3.8L supercharged models are especially hard on the 4T65-E due to higher torque output. Many 4T65-E transmissions fail between 80,000-120,000 miles.
Chevrolet Lumina(1 issue)
- 4T60E Automatic Transmission Failure1995-2001
The 4T60E transmission in the Lumina develops shifting problems, particularly the second clutch reaction plates that were improperly stamped in some production runs. The transmission can lose 1st or 4th gear, develop harsh shifts, or strip planetary gears causing complete loss of drive. GM issued a campaign for certain 1995 models with defective clutch plates.
Chevrolet Malibu(1 issue)
- 6T40 Transmission Shudder and Harsh Shifts2013-2016
The 2013-2016 Malibu with the 2.5L Ecotec engine uses the GM 6T40 6-speed automatic transmission that develops a pronounced shudder during light acceleration in the 25-45 mph range. The torque converter clutch wears prematurely, causing slippage and vibration that feels like driving on rumble strips. Harsh 1-2 and 2-3 shifts are also common. The 6T40 is sensitive to fluid condition and the issue worsens rapidly if the fluid is not changed on schedule.
Chevrolet Sonic(1 issue)
- 6-Speed Automatic Transmission Turbine Shaft Fracture2012-2015
Chevrolet recalled 21,567 Sonics from 2012-2014 for a tendency of the turbine shaft to fracture inside the 6-speed automatic transmission. The turbine shaft transfers energy from the engine to the wheels, and when it fractures, the transmission fails completely. The problem typically appears past 70,000 miles and usually requires complete transmission replacement. The 2012-2015 models are most commonly affected.
Chevrolet Trax(1 issue)
- 6-Speed Automatic Rough Shifting and Delayed Engagement2015-2022
The 6T40 automatic transmission exhibits rough or harsh shifts, delayed engagement from Park or Reverse, and occasional lurching. The valve body is the primary culprit, with wear on the pressure regulator bore causing erratic shift quality. Cold weather operation tends to make the issue more pronounced.

What does P0751 mean on Chevrolet?▼
P0751 stands for "Shift Solenoid A Performance/Stuck Off."

On Chevrolet specifically, this code is documented across 8 models.
What causes P0751 on Chevrolet vehicles?▼
Common causes on Chevrolet: 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.
