Reverse

Line Pressure

Line pressure which is not applied to the shift valves A and B operates the low and reverse brake and the reverse clutch directly. Therefore, pilot pressure and shift solenoid valves A and B are not related to gear change. Line pressure is applied to the pressure regulator valve as well, and line pressure is kept higher than the valve of driving forward.
