Pilot Pressure

Line pressure passes through the manual valve to shift valves A and B. Line pressure which has been sent through the manual valve to the shift valve A stops there. Line pressure which has passed through shift valve B is sent to the high clutch and shift valve A. Line pressure which has passed through shift valve A is sent to the 2-4 brake servo engagement side. Therefore, the 2-4 brake and the high clutch operate.
