The torque converter clutch functions similarly to the non-electronic type except instead of a single internal TCC solenoid, 2 solenoids are used. A standard TCC solenoid is used in conjunction with a Pulse Width Modulated (PWM) solenoid that regulates hydraulic pressure to make locking and unlocking of the TCC smoother.
