P0751

Shift Solenoid A Performance/Stuck Off

Q: Is it safe to drive with P0751?

You can usually drive it to a shop, but with the solenoid stuck off the transmission may not shift correctly or may enter limp mode, so avoid long trips.

Q: Can I just clear P0751?

It will clear, but comes back within a few drive cycles unless the solenoid, wiring, or fluid problem is repaired.

Transmission / shift control Generic OBD-II Medium

What it means

P0751 means shift solenoid "A" is either performing outside its expected range or stuck in the off position, so the transmission can't route hydraulic pressure to make a specific gear change. You may feel poor, delayed, or missing shifts, and the transmission can drop into limp mode to protect itself.

Medium

Can I keep driving? Usually drivable but you may lose a gear or drop into limp mode with harsh shifting — fine to reach a shop, but don't put off the repair.

How to diagnose & fix

Work through it in order

Scan for codes and read freeze-frame data to confirm the fault.
Check transmission fluid level and condition — top up or service if low, dirty, or burnt.
Inspect the shift solenoid A wiring and connector for damage or corrosion.
Test the solenoid's resistance and function against specification.
If the solenoid and circuit check out, inspect the valve body; replace the TCM only as a last resort. Clear and re-test.
