The main control assembly consists of a valve body and a solenoid body. Both the valve body and the solenoid body contain hydraulic shift valves. The solenoid body contains the shift solenoids that control the hydraulic valves. The solenoid body can be serviced with the main control 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 in the transmission, called the solenoid body strategy. A new solenoid body strategy must be downloaded into the PCM anytime a new solenoid body is installed.
