Solenoid Valve Body Assembly

WARNING: This page is about a different car, the 2002 Ford Escape, 2001 Mazda Tribute, and 2001 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Shift solenoids SSA and SSB may also be known as SS1 and SS2. The 3-2 timing/coast clutch solenoid may also be known as shift solenoid SS3 or SSC.

The solenoid valve body assembly contains Electronic Pressure Control (EPC) solenoid, Shift Solenoid "A" (SSA), Shift Solenoid "B" (SSB), 3-2 Timing/Coast Clutch solenoid (3-2T/CCS) and Torque Converter Clutch (TCC) solenoid. The shift solenoids are used for electronic shift scheduling. See Fig 1 .
When shift solenoid is always off, failure could be due to the PCM and/or vehicle wiring malfunction, and/or solenoid stuck in on position electrically, hydraulically or mechanically. For shift symptoms, see Fig 2 and Fig 3 .
When shift solenoid is always on, failure could be due to the PCM and/or vehicle wiring malfunction, and/or solenoid stuck in off position electrically, hydraulically or mechanically. For shift symptoms, see Fig 4 and Fig 5 .
