Second Gear

During second gear operation, solenoid No. 1 and No. 2 are on. Solenoid No. 1 has the same effect that it had in first gear with the 2-3 shift valve being held up by the spring at its base. Pressure from the manual valve flows through the 2-3 shift valve and holds the 3-4 shift valve up.

With solenoid No. 2 on, line pressure from the top of the 1-2 shift valve bleeds through the solenoid. Spring tension at the base of the 1-2 shift valve pushes it upward. Line pressure which was blocked, now is directed to the second brake (132), causing second gean The 3-4 shift valve maintains its position with line pressure from the 2-3 shift valve holding it up.
