P0751 on Volvo
Shift Solenoid A Performance/Stuck Off
P0751 on Volvo vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 1 Volvo model — most commonly on XC90. 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 Volvo range from $300 to $6,000, 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 Volvo by Model
Volvo XC90(1 issue)
- GM 4T65E Transmission Failure2003-2005
The 2003-2005 XC90 with the T6 engine uses a GM 4T65E transmission that is prone to failure. The transmission was designed for lower-torque applications and struggles with the T6's power. Overheating and internal component failure are common.

What does P0751 mean on Volvo?▼
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 Volvo specifically, this code is documented across 1 model.
What causes P0751 on Volvo vehicles?▼
