Shift Solenoid A Control Circuit Range/Performance
The P0972 code means the vehicle's onboard diagnostic system has detected: Shift Solenoid A Control Circuit Range/Performance. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- hard
- Estimated cost
- $150 - $800 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

What Are the Symptoms of P0972?
- Check Engine Light illuminated
- Harsh or delayed 1-2 shift
- Transmission slipping in low gears
- Vehicle may enter limp mode
What Causes P0972? (Most Likely First)
- Shift solenoid A sticking or partially blocked Very High
- Contaminated or degraded transmission fluid High
- Electrical resistance out of spec in solenoid A circuit Moderate
- Valve body wear affecting solenoid A operation Low
Can I Still Drive with P0972?
Short distances only. P0972 is rated moderate severity. Keep trips short and get it diagnosed soon rather than waiting for symptoms to worsen.
Frequently Asked Questions
What does shift solenoid A control?
Shift solenoid A typically controls the 1-2 shift or works with other solenoids to manage gear selection. The exact function varies by transmission model.
Can a fluid change fix P0972?
If the solenoid is sticking due to contaminated fluid, a fluid and filter change may resolve the issue. This is a recommended first step before replacing the solenoid.
Where is shift solenoid A located?
Shift solenoids are typically in the valve body inside the transmission. Accessing them requires removing the transmission pan and sometimes the valve body.
