Hydraulic Circuit When Moving Selector Lever From "N" to "D"
(Shift Phase)
1. Selector valve
5. 3-4 holding pressure shift valve
6. 3-4 Command valve
7. 3-4 shift pressure shift valve
8. 3-4 overlap control valve
10. Ball valve
13. Ball valve
14. 1-2/4-5 Command valve
19. Shift pressure control valve
27. B2 shift valve
The selector valve (1) opens the shift pressure (p-S) feed connection from the ball valve (10) with the shift valve B2 (27).
With the shift valve B2 (27) in the upper position, shift pressure (p-S_ travels behind the piston B2 (B2a) and simulta-
neously to the opposing face of the piston B2 (B2b). The brake B2 begins to close.
