| 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. |
| Downshift solenoid (2) | This solenoid controls the movement of rotary actuator (5) during downshifts. |
| Lockup solenoid (3) | This solenoid sends signal oil in order to activate the torque converter lockup clutch. This solenoid determines the pressure setting of the dual stage relief valve. |
| Rotary actuator (4) | This actuator controls movement of the rotary selector spool in selector and pressure control valve (8). |
| Pressure control valve (6) | This valve controls oil flow, the rate of pressure increase and of pressure decrease, and oil pressure in the clutches. |
| Manifold (7) | This manifold sends pump oil to rotary actuator (4). |
| Selector and pressure control valve (8) | This valve controls system pressure and the amount and direction of pilot pressure oil that is sent to pressure control valve (6). |
| Manifold (10) | This manifold sends oil to the clutches. |
| Transmission lubrication relief valve (11) | This relief valve controls the pressure of the transmission lubrication oil. |
