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 2 Chevrolet models — most commonly on Sonic, Trax. 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 $200 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 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." 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.'

On Chevrolet specifically, this code is documented across 2 models.
