Secondary Regulator Valve

This valve controls the hydraulic pressure to the torque converter and the hydraulic pressure to be used for lubrication to each transmission parts.

The hydraulic pressure sent from the primary regulator valve is applied to (1) and (2), trying to lower the valve.

On the other hand, the throttle pressure through the primary regulator valve is applied to (3), trying to raise the valve together with the spring force.

In this way, as the valve moves up and down, the line pressure is released through (4) for pressure control. Hydraulic pressure is supplied to each part of the transmission from (5) for lubrication purpose.
