LESSON 3: POWERTRAIN
Transmission Control Module (TCM) and Main Control Valve Body
Transmission Control Module (TCM) and Main Control Valve Body
The Main Control assembly (7A100) referred to as the mechatronic unit is made up of the following components,
the TCM processor, seven control solenoids, and a typical main control assembly. The main control component
houses valves and springs within the two halves (upper and lower). The mechatronic unit is attached to the case
of the transmission and is accessible through the pan/filter assembly.
CAUTION: When removing the TCM/main control valve body assembly, it is important to first
remove the connection adaptor. This is accomplished by releasing the white locking mechanism and
pulling out on the adaptor. Failure to remove the adaptor before removing the TCM/main control
valve body assembly will result in damage to the adaptor or TCM/main control valve body assembly.
