Abstract
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.
