Shift Phase
Via the 1-2 and 4-5 shift solenoid (1), the shift valve pressure (p-SV) is directed onto the end face of the command
valve (5). The command valve (5) is moved and the shift pressure (p-S) coming from the shift pressure shift valve
(3) is directed via the command valve (5) onto driving clutch K1 (6). Simultaneously the multi-disc holding clutch B1
(7) is subjected to overlap pressure by the overlap valve (2).
The multi-disc holding clutch B1 (7) pressure acting on the end face of the shift pressure shift valve (3) is replaced
by the working pressure (p-A). The rising shift pressure (p-S) at driving clutch K1 (6) acts on the annular face of the
overlap regulating valve (2) and reduces the overlap pressure regulated by the overlap regulating valve (2). When
a corresponding pressure level is reached at the holding pressure shift valve (4), this valve switches over.
Second Gear Engaged
After the gearchange is complete, the pressure on the end face of the command valve (5) is reduced via the 1-2
and 4-5 shift solenoid valve (1), and the command valve (5) is pushed back to its basic position. Via the holding
pressure shift valve (4) the working pressure (p-A) now passes via the command valve (5) to driving clutch K1 (6).
