Abstract

A gearbox actuator unit (14) is configured to be arranged on a gearbox (10) and includes a housing (22), a control device (24), and an actuator (28, 30). The housing (22) is configured to attach to a gearbox housing (12) and to seal the gearbox housing (12). The control device (24) is electrically connected to the actuator (28, 30) and activates the actuator (28, 30). A pinon of the actuator (28, 30) is configured to actuate a rack of a shift fork (18, 20) of the gearbox (10) and can be connected to the shift fork (18, 20) of the gearbox (10). The control device (24) and the actuator (28, 30) are arranged within the housing (22), with the pinion extending through an opening of the housing. A gearbox (10) with a housing (12) having an opening (44) receives the actuator unit (14), which closes and seals the opening (44).
