Reverse Brake Sequence Valve
- The reverse brake sequence valve reduces the shock when the selector lever is shifted to R position, and it is controlled by the line pressure which acts on the direct clutch outer piston. The line pressure acts on both circuits A and B at the same time when the selector lever is at R position. The outer piston operates after the inner piston, since circuit B will not open until hydraulic pressure A on this valve or the line pressure on the inner piston overcomes the valve spring tension.
- When the selector lever is in third gear at D range, only the outer piston can operate since circuit B is closed by the manual valve.
