Hydraulic Flow: Notes

As the engine turns, the CVTF pump starts to operate. Transmission fluid (CVTF) is drawn through the CVTF strainer (filter) and discharged into the hydraulic circuit. Then, CVTF flowing from the CVTF pump flows to the pressure high (PH) regulator valve and becomes the pressure high (PH) pressure. PH pressure flows to the pulley control valves and then to the pulleys.

The PCM actuates the solenoid valves to control hydraulic pressure shifting pulley ratio and engaging the start clutch.
