An actuating device for automation of a manual transmission of a vehicle has a housing in which a first main piston and a second main piston are slidably supported. A control lever, fixedly connected to the actuator shaft of the manual transmission, is provided to select a gate of the manual transmission. The control lever is positioned between the first and second main pistons. A first valve hydraulically controls and actuates the first main piston by a hydraulic medium. A second valve hydraulically controls and actuates the second main piston by the hydraulic medium.
