Torque Converter Clutch Released

2345 fluid seats the ball check valve against the reverse passage and enters the 2345 or reverse fluid circuit.

2345 or reverse fluid is directed through the TCC PWM solenoid valve filter to the TCC PWM solenoid valve. However, depending on the shift pattern, the TCM keeps the pulse width modulated (PWM) solenoid de-energised blocking filtered 2345 or reverse fluid from entering the TCC signal fluid circuit, thereby keeping the torque converter clutch released.
