Patent ID: 7052431

Claim:
An automatic transmission which has at least six selectable forward speeds, the automatic transmission comprising: a reduction planetary gearset which reduces speed of rotation input from an engine; a plurality of planetary gearsets disposed behind the reduction planetary gearset, the plurality of planetary gearsets comprising a ring gear as an input member which inputs reduced rotation from the reduction planetary gearset, individual planetary gearsets respectively comprising a single set of pinion gears; a plurality of clutches which are disposed radially beyond the plurality of planetary gearsets; and a plurality of brakes which are disposed radially beyond the plurality of clutches, the forward speeds of the transmission being selectable through a combination of engagement and disengagement of the plurality of clutches and the plurality of brakes, each brake overlapping with a corresponding clutch in the axial direction, wherein the plurality of planetary gearsets further comprises an output member which is disposed outside an outer circumference of the plurality of clutches and inside an inner circumference of the plurality of brakes.
