The reverse gear ratio is defined by a first reverse gear wheel mounted freely rotatable on the first secondary shaft and connectable in rotation with the latter by one of the selector devices. A parking gear wheel is rigidly mounted on the first secondary shaft The parking gear wheel is mounted adjacent to a roller bearing which rotatably supports the first secondary shaft within the casing and which is axially interposed between the parking gear wheel and the first reverse gear wheel.
