P0973 Shift Solenoid A Control Circuit Low
TCM detects voltage on shift solenoid A control circuit below threshold, indicating short to ground or driver fault.
Is it safe to drive with P0973?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
Common causes
- Most likelyShort to ground
- Less likelyConnector pins corroded - high contact resistance
- Less likelyHarness chafing through insulation
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
