P0751 on Honda
Shift Solenoid A Performance/Stuck Off
P0751 on Honda vehicles indicates shift solenoid a performance/stuck off. Au7o has documented this code across 3 Honda models — most commonly on Odyssey, Pilot, Prelude. 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 Honda range from $1,500 to $3,500, 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 Honda by Model
Honda Odyssey(1 issue)
- Automatic Transmission Complete Failure (2nd Gen)1999-2004
Complete transmission failure due to faulty bearings and defective 3rd clutch components in 4-speed (1999-2001) and 5-speed (2002-2004) automatic transmissions. The 2002-2004 transmission can suddenly downshift from 5th to 2nd gear causing dangerous drivability issues. Honda recalled 1.1 million vehicles in 2004 and settled class-action lawsuit in 2006.
Honda Pilot(1 issue)
- ZF 9-Speed Transmission Rough Shifting and Hesitation2016-2019
The ZF 9HP transmission produces rough and delayed shifting, loud noises during shifting, sudden harsh accelerations/decelerations, jerking/hesitating at all speeds, and loss of power. Problems stem from improper software calibration and electrical connection defects. Honda issued multiple TSBs but many issues persist until 2019 models.
Honda Prelude(1 issue)
- 5th Generation Automatic Transmission Failure1997-2001
The 4-speed automatic transmission (MAXA/M6HA) in the 1997-2001 Prelude is prone to premature failure, a problem shared with many late-1990s Honda automatic transmissions. The 3rd and 4th gear clutch packs wear prematurely, and the torque converter can develop shudder. High-mileage automatics often slip, flare between shifts, or fail to engage gears. Honda automatics of this era were undersized for the power output of the H22A engine.

What does P0751 mean on Honda?▼
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 Honda specifically, this code is documented across 3 models.
What causes P0751 on Honda vehicles?▼
Common causes on Honda: 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.
