Abstract

A gearbox for a motor vehicle is provided that includes, but is not limited to two coaxial input shafts carrying gearwheels, and three layshafts selectively drivable by the input shafts. Each gearwheel of the input shafts meshes with at least one gearwheel of the two layshafts. The three layshafts carry three pinions meshing with a same output gearwheel, and the third layshaft further carries a reverse gearwheel meshing with a gearwheel of the first layshaft.
