Torque Converter Clutch Solenoid: Description and Operation
Solenoid Valves SLT, TCM FA 57 (531)
Solenoid Valves SLT, TCM FA 57 (531)
Main use
To regulate the transmission system pressure.
Type
Electromagnetic, PWM governed.
Activation
The solenoid is governed from pin 35 (B) on TCM using a 300 Hz voltage. Grounding takes place on pin 15 (B) on TCM. The current varies between 0
- 1000 mA. The solenoid is open when current is not applied. 0 A = high oil pressure 1000 mA = low oil pressure.
