Solenoid and Pressure Switch Assembly

The Solenoid and Pressure Switch assembly, located on the transmission, is used to control the shifting of the transmission. Power for the assembly is provided on circuit T16 from the transmission control relay. The Transmission Control Module (TCM) provides the ground path for the various solenoids and pressure switches depending on operating conditions. This assembly is also case grounded to the transmission.

The following circuits are controlled by the TCM for the Solenoid and Pressure Switch Assembly
- T20 - Low/Reverse solenoid
- T19 - 2/4 solenoid
- T60 - Overdrive solenoid
- T59 - Governor Pressure Solenoid
- T50 - Low/Reverse pressure switch
- T47 - 2/4 pressure switch
- T9 - Overdrive pressure switch
