Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Hydraulic Control: Notes
The hydraulic control system is controlled by the CVTF pump, the valves, and the solenoid valves. The CVTF pump is driven by the input shaft. The CVTF pump and the input shaft are linked by the CVTF pump drive chain and the sprockets. Fluid from the CVTF pump flows through the pressure high (PH) regulator valve to maintain specified pressure to the drive pulley, the driven pulley, and the manual valve.
The lower valve body assembly includes the main valve body, the secondary valve body, the CVT driven pulley pressure control solenoid valve, the CVT clutch pressure control solenoid valve, and the CVT drive pulley pressure control solenoid valve.
The manual valve body is bolted on the intermediate housing, and houses the manual valve which switches hydraulic pressure to meet with the shift lever position.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
