Operation Of Components In The Transmission Hydraulic Control    
Component     Operation (Function)    
Upshift solenoid (1)     This solenoid controls the movement of rotary actuator (5) during upshifts.    
Pressure control valve (2)     This valve controls oil flow, the rate of pressure increase and the rate of pressure decrease, and oil pressure in the clutches.    
Downshift solenoid (3)     This solenoid controls the movement of rotary actuator (5) during downshifts.    
Selector and pressure control valve (4)     This valve controls system pressure and the amount and direction of pilot pressure oil that is sent to pressure control valve (2).    
Rotary actuator (5)     This actuator controls movement of the rotary selector spool in selector and pressure control valve (4).    
Transmission lubrication relief valve (6)     This relief valve controls the pressure of the lubrication oil to the transmission.    
Manifold (7)     This manifold sends pump oil to rotary actuator (5).    
Manifold (9)     This manifold sends oil to the clutches.
