Electronic Pressure Control (EPC) Solenoid
WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, 2003 Ford Excursion, and 2003 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
The Electronic Pressure Control (EPC) pressure output from the variable force solenoid is NOT adjustable. Any modification to the electronic pressure control solenoid will affect the transmission warranty.
- The EPC solenoid is a variable-force solenoid.
- The variable-force type solenoid is an electrohydraulic actuator combining a solenoid and a regulating valve.
- It supplies electronic pressure control that regulates transmission line pressure and line modulator pressure.
- This is done by producing resisting forces to the main regulator and the line modulator circuits. These two pressures control clutch application pressures.
