Shift Solenoid Pressure Control A (SSPCA), Shift Solenoid Pressure Control B (SSPCB), Shift Solenoid Pressure Control C (SSPCC), Shift Solenoid Pressure Control D (SSPCD) and Shift Solenoid Pressure Control E (SSPCE)
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
The intermediate (Shift Solenoid Pressure Control C (SSPCC)), low/reverse (Shift Solenoid Pressure Control E (SSPCE)) and Overdrive (O/D) (Shift Solenoid Pressure Control B (SSPCB)) clutches are each controlled by a directly proportional Variable Force Solenoid (VFS). The coast (Shift Solenoid Pressure Control A (SSPCA)) and the direct clutch (Shift Solenoid Pressure Control D (SSPCD)) are each controlled by an inversely proportional VFS. All shift pressure solenoids are electronically controlled by the PCM which varies the current from 0 to 1 amp (direct proportional) or 1 to 0 amp (indirectly proportional).
