A gear shift device for vehicles with a mechanical, manually operable gearbox ( 9 ) for the vehicle ( 2 ). A gear level ( 1 ) is linked to the hydraulic master ( 55, 55', 56, 56' ) to respective slave cylinders ( 8, 18 ) for engagement or disengagement of gears during a manual mode of operation for the gear shift device. The gear level ( 1 ) is arranged to be brought from a position, wherein a gear is engaged, via a neutral or free position. By means of the gear level ( 1 ), the gear shift device can be brought into an automatic mode of operation (A). An electronic control device ( 44 ) is arranged to receive signals concerning a chosen mode of operation and driving parameter values. When an automatic mode of operation is chosen, the connection between the master cylinders ( 5, 15 ) and the slave cylinders ( 8, 18 ) is broken, and a connection is established between the control device ( 44 ) and the slave cylinders ( 8, 18 ) for automatic control of the slave cylinders. |
