Valve Body: Description and Operation

- The main control valve body houses the hydraulic valves and shift solenoid valves. These valves direct fluid flow, restrict fluid flow, and change fluid pressure. The main control valve body receives signals from the solenoid valve body and changes electrical signals into hydraulic actions. The actions control the operation of the hydraulic clutches and the 2-4 band; and supply lubrication to the transaxle.
- The main control valve body consists of four sections:
- the upper control valve body
- main control valve body
- premain control valve body
- lower control valve body
