Hydraulic Circuit During Shift Phase

14. 1-2/4-5 command valve
15. 1-2/4-5 holding pressure shift valve
16. 1-2/4-5 shift valve
18. 1-2/4-5 pressure overlap control valve
The shift valve pressure (p-SV) is directed onto the end face of the 1-2/4-5 command valve (14) via the 1-2/4-5 shift
solenoid valve. The command valve (14) moves up and the shift pressure (p-S) coming from the 1-2/4-5 shift pressure
shift valve (16) is routed via the command valve (14) to clutch C1. Overlap pressure is simultaneously applied to brake
(B1) from the pressure overlap control valve (18). The B1 pressure acting on the end face of shift pressure shift valve (16)
is replaced by operating pressure (p-A). The increasing shift pressure (p-S) on clutch C1 acts on the annular surface of
the pressure overlap control valve (18) and reduces the overlap pressure controlled by the pressure overlap control valve
(18). It will shift at a corresponding pressure on the holding pressure shift valve (15).
