How is the torque converter clutch solenoid controlled?
The fluid pressure that applies and releases the torque converter lockup clutch is controlled by the torque converter clutch solenoid. The opening and closing of the TCC solenoid valve is controlled by the transmission control module (TCM) or powertrain control module (PCM), depending on the vehicle.
What are the symptoms of a torque converter clutch failure?
The symptoms are different a torque converter clutch solenoid that fails in the open position… The symptoms of a torque converter clutch solenoid that fails while in the open position are quite different from a solenoid that fails in the closed position, as described above.
