Abstract
An electric gearshift mechanism for a change-speed gearbox of a motor vehicle with selector gates has an electric motor and a gear shifting member. The gear shifting member can be moved in two substantially mutually transverse shifting movements. The gear shifting member includes a threaded spindle having an axis of rotation drivably connected to the motor carrying a nut having a finger for preselecting selector gates. A linear guide conducts the nut along the axis and a clutch rotatably connects the nut and the spindle.
