Shift Solenoid: Description and Operation
Solenoid Valves SLT, TCM FA 57 (531)
Solenoid valves TCM, SLT (531)
Location
Shift solenoid, S1-S5 (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 300Hz 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. 0A = high oil pressure 1000mA = low oil pressure.
