P0751 — Shift Solenoid "A" Performance / Stuck Off
Drive with caution — fix soon.
What P0751 means
P0751 means the transmission control module has detected that shift solenoid "A" is stuck off or not performing as expected. This solenoid helps control the flow of transmission fluid that engages specific gears. When it sticks, the transmission may not shift correctly, leading to hard shifts or being stuck in one gear.
Common symptoms
- Check Engine light is on
- Transmission shifts harshly or with a noticeable jolt
- Transmission feels stuck in one gear
- Delayed or missing gear changes
- Reduced fuel economy
Common causes
- Faulty or stuck shift solenoid "A"
- Low or dirty transmission fluid
- Wiring or connector problems in the solenoid circuit
- Clogged transmission valve body or passages
- Faulty transmission control module
Typical repair cost
$150 – $500
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0751 code?
For short trips, usually yes, but you shouldn't rely on it. The transmission may shift hard or stay stuck in one gear, which can wear down internal parts. Get it checked soon and avoid towing or long highway drives.
How much does it cost to fix a P0751?
Repairs typically range from about $150 to $500. A simple fluid service or wiring fix is on the lower end, while replacing the shift solenoid or valve body work costs more.
Is a P0751 code serious?
It's a moderate concern. It won't usually leave you stranded right away, but ignoring it can lead to more expensive transmission damage, so it's best to address it promptly.
What does shift solenoid "A" actually do?
It controls the flow of transmission fluid that engages certain gears. When it sticks off, your transmission can't shift properly, which is why you may feel it stuck in gear or shifting roughly.
