A kinematic arrangement of a multiple-speed automatic transmission for an automotive vehicle includes three simple planetary gear units, hydraulically actuated clutches and brakes applied and released selectively, and an overrunning clutch that produces a one-way drive connection between the sun gear of the first gear unit and a nonrotating member, such as the transmission casing. Each planetary gear unit includes a sun gear, a ring gear surrounding the sun gear, a carrier, and a set of planet pinions in continuous meshing engagement with the sun gear and ring gear and rotatably supported on the carrier.

Ensemble cinématique d'une transmission automatique à vitesses multiples pour un véhicule automobile comprenant trois groupes d'engrenage planétaire simples, des embrayages et des freins hydrauliques engagés et relâchés sélectivement et une roue libre qui produit une connexion d'entraînement à sens unique entre le manchon à planétaire du premier groupe d'engrenage et un élément non rotatif, comme la boîte de transmission. Chaque groupe d'engrenage planétaire comprend un manchon à planétaire, une couronne entourant le manchon, un transporteur et une série de pignons satellites qui s'engrènent en continu avec le manchon et la couronne et qui sont supportés de manière à tourner sur le transporteur.
