Abstract
A transmission has a pair of parallel shafts, a first shaft being connected through a torque converter with a vehicle engine and a second shaft carrying an output gear which is adapted to engage with a differential unit for the front wheel drive axle. The first shaft is provided with a first gear system thereon which includes one or more planetary gearsets, and the second shaft is provided with a second gear system thereon which includes a planetary gearset. A sun gear constituting the planetary gearset of the second gear system is integrally provided on the second shaft so that it can rotate together with the second shaft. A brake and a one-way clutch for controlling the action of this planetary gearset are provided between the second shaft and the case in such a manner that the brake can restrict the rotation of the second shaft, and that the one-way clutch can prohibit the rotation of the second shaft in one direction. The output gear is carried rotatably on the second shaft.
