Shift Solenoid Pressure Control Solenoids
WARNING: This page is about a different car, the 2012 Ford F550 Super Duty and 2012 Ford F450 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).
