Hydraulic Control

The lower valve body assembly includes the main valve body, the secondary valve body, the CVT driven pulley pressure control valve, the CVT drive pulley pressure control valve, the CVT start clutch pressure control valve, and the inhibitor solenoid valve. These valve bodies are positioned on the lower portion of the transmission housing. The manual valve body is bolted on the intermediate housing.

The main valve body contains the start clutch shift valve, the shift inhibitor valve, and the lubrication valve. The secondary valve body contains the pressure high (PH) regulator valve, the pressure high control (PHC) shift valve B, the start clutch back-up valve, the clutch reducing valve, and the start clutch accumulator. The CVT driven pulley pressure control valve contains the pulley control valve A and the driven pulley control valve with the solenoid. The CVT drive pulley pressure control valve contains the pulley control valve B and the drive pulley control valve with the solenoid. The CVT start clutch pressure control valve consists of the start clutch pressure control valve and the solenoid. These solenoids are controlled by the TCM. The manual valve body contains the manual valve and the reverse inhibitor valve.

The ATF pump is located on the transmission housing, and it is linked with the input shaft by the sprockets and the sprocket chain. The pulleys, forward clutch, and start clutch receive fluid from their respective feed pipes, and the reverse brake receives fluid from internal hydraulic circuit.
