The main control assembly consists of the valve body and the solenoid body. Both the valve body and the solenoid body contain hydraulic switching valves. The solenoid body contains the shift solenoids, which control the hydraulic valves. The solenoid body can be serviced as an assembly with the solenoids, or the solenoids can be serviced individually. The solenoid body is controlled by the PCM. The PCM has software stored in it specific to the solenoid body, currently referred to as the solenoid body strategy. A new solenoid body strategy must be downloaded to the PCM each time a new solenoid body is installed.
The pump assembly contains the Main Pressure Regulator Valve assembly and the TCC Regulator Valve assembly.
