The sun gear RPM is greater than the carries RPM indicating that the output rotation has been reduced compared to input rotation. In 1st gear operation, the front carrier is locked and the front sun gear rotates counterclockwise. However, in 2nd gear operation, the front sun gear is locked and the front carrier rotates clockwise. Therefore , the front internal gear rotates faster than in 1st gear, and output rotation in 2nd gear becomes faster than the rotation in 1st gear.

2nd Gear

Pilot Pressure

Since shift solenoid valve is OFF, pilot pressure is blocked and the shift valve A does not operate. Since the shift solenoid valve B is ON, the shift valve B operates. Line pressure passes through the manual valve to shift valves A and B, and operates the 2-4 brake servo engagement side and the low clutch in succession.
