Solenoid Valve Body Assembly

WARNING: This page is about a different variant/trim than selected.

NOTE: Shift solenoids SSA, SSB and SSC may also be known as SS1, SS2 and SS3.

The solenoid valve body assembly contains Electronic Pressure Control (EPC) solenoid, Shift Solenoid "A" (SSA), Shift Solenoid "B" (SSB), Shift Solenoid "C" (SSC) and Torque Converter Clutch (TCC) solenoid. The shift solenoids are used for electronic shift scheduling. See SHIFT SOLENOID OPERATION table.
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 1 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 2 and Fig 4 .
