P0972
Shift Solenoid A Control Circuit Range/Performance
Transmission controls
Generic OBD-II
Medium
What it means
P0972 means the transmission control module sees the shift solenoid 'A' control circuit responding outside its expected range — the solenoid isn't performing as commanded. It typically causes harsh or missed shifts and can put the transmission into limp mode, but it does not stop the engine from starting.
Medium
Can I keep driving? You can usually drive, but expect harsh or missed shifts and possible limp mode — repair it before it strains the transmission.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh shifting or failure to shift into a gear
- Transmission slipping or not engaging properly
- Transmission stuck in limp mode
Common causes
Most likely first
- Failed shift solenoid 'A'Likely
- Damaged wiring or high resistance in the solenoid circuitCommon
- Loose or corroded electrical connectorCommon
- Faulty transmission control module (TCM) — less commonLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the shift solenoid 'A' connector and harness for damage or corrosion.
- Check the solenoid circuit for correct resistance and a good ground/feed.
- Test the shift solenoid electrically and mechanically; replace it if out of spec.
- If the circuit and solenoid check out, have the TCM evaluated. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0972?+
For short distances usually, but shifting may be rough or the transmission may limp. Extended driving in this state can accelerate wear, so fix it soon.
Can I just clear P0972?+
Clearing removes the light temporarily, but the code returns until the solenoid circuit performance problem is repaired.
