An automatic transmission which has at least six selectable forward speeds, the automatic transmission being comprised of a reduction planetary gearset which reduces speed of rotation input from an engine, a plurality of planetary gearsets disposed behind the reduction planetary gearset, 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 plurality of planetary gearsets are comprised of a ring gear as an input member which inputs reduced rotation from the reduction planetary gearset, and individual planetary gearsets are respectively comprised of a single set of pinion gears. The forward speeds of the transmission are selectable through a combination of engagement and disengagement of the plurality of clutches and the plurality of brakes. Each brake overlaps with a corresponding clutch in the axial direction.
