P2769
Torque Converter Clutch Circuit Low
Transmission controls
Generic OBD-II
Medium
What it means
P2769 means the torque converter clutch (TCC) circuit is reading low — often a short to ground or an open. The TCC locks the converter to link the engine and transmission for cruising efficiency, so this fault can prevent lockup, cause shudder, and lower fuel economy. It affects the transmission, not engine starting.
Medium
Can I keep driving? Usually yes, but you may notice a shudder, lost lockup, or slightly higher rpm on the highway. Get it serviced to protect fuel economy and the converter.
Common symptoms

How to diagnose & fix
Work through it in order
- Scan for related codes (P0740, P0741, P0743, P2770) and read freeze-frame.
- Check transmission fluid level and condition.
- Inspect the TCC solenoid wiring and connector for shorts, opens, or corrosion.
- Measure the solenoid's resistance against spec.
- Replace the TCC solenoid if faulty; verify the module last.
