The transmission solenoid/TRS assembly is internal to the transmission and mounted on the valve body assembly. The assembly consists of five solenoids that control hydraulic pressure to five of the friction elements (transmission clutches), and the torque converter clutch. The pressure control solenoid is located on the side of the solenoid/TRS assembly. The solenoid/TRS assembly also contains the Transmission Range Sensor (TRS) and five pressure switches that feed information to the TCM.
