Shift Solenoid (On/Off) Valves
WARNING: This page is about a different car, the 2006 Mercury Milan and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The shift solenoid (on/off) valves switch the different oil passages in the valve body to direct the pressure to the individual clutches and bands.
The shift solenoid valves are needed for direct actuation of the individual clutches and bands.
