Abstract
A five-speed automatic transmission for a vehicle includes a transmission housing, an input member, an output member, a plurality of planetary gearsets for changing a ratio of torque between the input member and the output member, a plurality of clutch assemblies to selectively couple the input member to predetermined gears of the planetary gearsets, a plurality of brake assemblies to selectively couple predetermined gears of the planetary gearsets to the transmission housing, and a structure for allowing the output member and a planetary carrier for one of the planetary gearsets and an annulus gear of two other of the planetary gearsets to rotate simultaneously.
