P2760
Torque Converter Clutch Pressure Control Solenoid Control Circuit Intermittent
The TCC pressure control solenoid shows intermittent electrical or hydraulic faults. Wiring faults of this kind typically come from chafing, water ingress at connector seals, or pin push-back — a wiggle test on the harness while the code is active often confirms the location.
