Shift Solenoid A Control Circuit Range/Performance
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.
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.
Real-world scan data
Figures reflect only diagnostic scans recorded through our own apps and tools. Cars are typically scanned because a symptom or warning light prompted it, so these counts describe our scan records — not the incidence of faults in any model, and not the quality, reliability, or safety of any vehicle.

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.
