Hydraulic Control: Notes

The hydraulic control system is controlled by the ATF pump, the valves, and the solenoids. The ATF pump is driven by the input shaft. The ATF pump and the input shaft are linked by the ATF pump drive chain and the sprockets. Fluid from the ATF 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 valve, the CVT start clutch pressure control valve, and the CVT drive pulley pressure control 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.
