"L" Range

The line pressure which acted on the manual valve passes through the forward clutch accumulator and causes the forward clutch to engage. At this time, the accumulator temporarily Repressurizes the line pressure to engage the forward clutch according to the throttle opening so as to reduce the shock caused when the forward clutch is engaged.

Furthermore, with the shift solenoid valve No. 1 turned ON and the shift solenoid valve No. 2 OFF, the 3 - 4 shift valve moves to the left because its right side is subject to the line pressure. In this way, the line pressure which acted on the 3 - 4 shift valve, passes through the valve and the coast clutch modulator valve, to cause the coast clutch to engage.

Also, as the 1 - 2 shift valve moves to the right with the line pressure applied to its left side, the hydraulic pressure regulated in the low coast modulator valve passes through the 1 - 2 shift valve and causes the 1st and Reverse brake to engage.
