Torque Converter Clutch Solenoid: Description and Operation
Solenoid Valves SLS, TCM FA 57 (531)
Solenoid valves TCM, SLS (531)
Location
Solenoid valves, TCM (531)
Main use
To regulate the oil pressure to the various clutches/brakes in the transmission.
Type
Electromagnetic, PWM governed.
Activation
The solenoid is governed from pin 26 (B) on TCM using a 300Hz PWM voltage. Grounding takes place on pin 36 (B) on TCM. The current varies
between 0-1000 mA. The solenoid is open when current is not applied. 0A = high oil pressure 1000mA = low oil pressure.
