Accumulator Switch Valve: Operation
- The accumulator switch valve is pushed upward by spring force. While in the forward drive range, line pressure (1) from the manual valve is applied to the top end of the accumulator switch valve and pushes the valve downward. In this condition, high clutch operation pressure (23) is applied to the high clutch accumulator via the valve.

- While in R position the valve is pushed upward by the spring force because line pressure (1) is drained. In this condition, low and reverse brake operation pressures (20) are applied to the high clutch accumulator via the valve.
