P2769 Torque Converter Clutch Solenoid Circuit Low
The TCM reads a voltage below threshold on the torque converter clutch (TCC) solenoid control circuit. The TCC may not engage, increasing fuel consumption and converter heat.
Is it safe to drive with P2769?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
Common causes
- Most likelyControl wire shorted to ground
- PossibleInternal solenoid short
- Less likelyConnector pins corroded - high contact resistance
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
