Shift Solenoids - (SSA, SSB, SSC, SSD)

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

Four On/Off shift solenoids allow the powertrain control module to control shift scheduling.

The solenoids are 3-way, normally open style.
The shift solenoids SSA, SSB, SSC and SSD provide gear selection of 1st through 5th and reverse gears by directing PC pressures to the appropriate elements.

Coast braking and manual gears are also controlled by the shift solenoids.
