Main Control Assembly
The hydraulic system of this transmission includes the fluid pump, a main control assembly and fluid passages in the transmission case and center support to apply the clutches.
The main control assembly has an upper valve body assembly, a separator plate and a lower valve body assembly. The lower valve body assembly has 7 solenoids to control the valves in the main control.
The TSS, OSS, TR and TFT sensors are all part of the main control assembly leadframe.
