Pilot Pressure

Line pressure passes through the manual valve to shift valves A and B. Line pressure which has passed through shift valve A is applied to the 2-4 brake servo engagement side and shift valve B. Line pressure which has passed through shift valve B is applied to the low clutch and the servo release timing valve operational side. Line pressure which has passed through the manual valve to shift valve B is applied to the high clutch and the servo release timing valve. Line pressure which has passed through the servo release timing valve is applied to the 2-4 brake servo release side and releases the 2-4 brake. Therefore, the low clutch and the high clutch operate.
