Torque Converter Clutch PWM Solenoid Valve

TCC PWM Solenoid:

This electrical device is used to control fluid acting on the Torque Converter Clutch (TCC) valve which then controls TCC apply and release. This solenoid is attached to the control valve body within the transmission. The TCC Pulse Width Modulated (PWM) solenoid is used to provide smooth engagement of the torque converter clutch by operating on a negative duty cycle percent of "ON" time.
