• In N position, spring force and line pressure (7) are applied to the right side of the piston, pushing it to the left side.
• When R position is selected from N position, line pressure (6), which engages the reverse clutch, is applied to the N-R accumulator.
• As a result, line pressure (6) overcomes the combination of line pressure (7) and spring force, and the piston moves to the right side.
• This movement of the piston moderates a rapid increase in line pressure (6).
