Abstract

In a control arrangement for an automated gear shift transmission, particularly a dual clutch transmission with a partial transmission having two gears which must not be simultaneously engaged, simultaneous engagement of the two gears of the partial transmission is prevented by a gear actuation system which has a first and a second gear slide wherein a second gear shift control pressure of the second gear slide counteracts the first gear shift control pressure of the first gear slide so that the first gear slide is blocked by the second gear shift control pressure.
