P0751 on Toyota
Shift Solenoid A Performance/Stuck Off
P0751 on Toyota vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 6 Toyota models — most commonly on Camry, GR Corolla, GR86. 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 Toyota range from $100 to $2,800, 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 Toyota by Model
Toyota Camry(1 issue)
- 8-Speed Transmission Hesitation/Jerking2018-2023
The 8-speed automatic transmission can exhibit hesitation, jerky shifts, or a delayed response when accelerating from a stop. Some owners report the transmission feels confused about which gear to select at low speeds.
Toyota GR Corolla(1 issue)
- iMT Rev-Match System Interference and Shift Feel2023-2025
The intelligent Manual Transmission (iMT) rev-match system can interfere with smooth shifting, causing unexpected RPM blips and a disconnected shift feel. The system sometimes over-revs or under-revs during downshifts, and the clutch pedal feel is reported as vague.
Toyota GR86(1 issue)
- Manual Transmission Throw-Out Bearing Noise2022-2025
GR86 models with the 6-speed manual develop throw-out bearing noise, typically a chirping or squealing sound when the clutch pedal is depressed or released. The bearing wears prematurely, especially in stop-and-go traffic. Not an immediate failure risk but worsens over time.
Toyota Grand Highlander(1 issue)
- 8-Speed Automatic Harsh Shifting and Torque Converter Shudder2024-2026
The 8-speed automatic transmission in the turbocharged Grand Highlander exhibits harsh 1-2 and 2-3 shifts during light throttle driving, along with torque converter shudder at highway speeds between 40-60 mph. The issue is more pronounced when the transmission is cold.
Toyota Tacoma(1 issue)
- Manual Transmission Grinding/Notchy Shifts2016-2023
The 6-speed manual transmission can exhibit grinding when shifting, particularly into 2nd or 3rd gear, and generally notchy shift feel. This is often related to the synchros or the clutch system hydraulics.
Toyota Tercel(1 issue)
- Automatic Transmission Failure (A132L)1990-1999
The A132L 3-speed automatic transmission in the Tercel is prone to premature failure, typically presenting as harsh shifting, slipping, or complete loss of forward gears. The transmission was designed for economy driving and struggles with sustained highway use or towing. Internal clutch pack wear and valve body issues are the most common failure modes. Many owners convert to manual transmission or source used replacements rather than rebuild.

What does P0751 mean on Toyota?▼
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 Toyota specifically, this code is documented across 6 models.
What causes P0751 on Toyota vehicles?▼
Common causes on Toyota: 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.
