Torque Converter Clutch Solenoid: Description and Operation

PURPOSE
The purpose of the Transmission Converter Clutch (TCC) feature is to eliminate the power loss of the torque converter when the vehicle is in a cruise mode.

OPERATION
The TCC System uses a solenoid operated valve to couple the engine flywheel to the output shaft of the transmission through the torque converter. This reduces the slippage losses in the converter, which increases fuel economy.
