Shift Solenoid Pressure Control Solenoids
WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. 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 Shift Solenoid Pressure Control B (SSPCB) clutches are each controlled by a directly proportional 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).
