Main Control Valve Body Mechanical Operation
The main control consists of a valve body assembly with solenoids that are controlled by a PCM for gas engine applications and a TCM for diesel engine applications. The PCM or TCM operates the electrical components to provide refined engagement feel, shift feel, and shift scheduling.
