The device is provided with an electronic control device (DCE) designed to automatically place the gearbox (1), or in other words the selector shaft (10), in the position corresponding to the gear selected by the driver or automatically determined as a function of the speed of the vehicle. The electronic control device (DCE) comprises, in particular, means for down-shifting gently despite the absence of a synchronizer in the gearbox.
