Main Valve Body
The main valve body contains the start clutch shift valve, the shift inhibitor valve, and the lubrication valve.
- Start Clutch Shift Valve
When a control system malfunction occurs, the start clutch shift valve receives shift inhibitor pressure (SI) and covers the port of lubrication pressure by-pass circuit.
- Shift Inhibitor Valve
The shift inhibitor valve switches the fluid passage to switch the start clutch control from electronic control to hydraulic control when the electronic control system is faulty.
- Lubrication Valve
The lubrication valve stabilizes the lubrication pressure to the internal circuit.
