Main Valve Body
The main valve body contains the start clutch shift valve, the shift inhibitor valve, the lubrication regulator valve, and the cooler relief valve.
- Start Clutch Shift Valve
When a control system malfunction occurs, the start clutch shift valve receives shift inhibitor pressure (SI) and covers the lubrication pressure bypass circuit port.
- 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 Regulator Valve
The lubrication regulator valve stabilizes the lubrication pressure to the internal circuit.
- Cooler Relief Valve
The cooler relief valve stabilizes the CVTF cooler pressure and recirculation pressure to the CVTF cooler and to the internal circuit.
