ABSTRACT:
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.
