Abstract
An automatic transmission which can establish properly separated gear ratios of forward ten gears or eleven gears and reverse two gears, which is simple and compact and can comfortably change gears. A fourth sun gear of a speed-changing dual planetary gear is connected to a speed-reducing common ring gear of a speed-reducing dual planetary gear through a first clutch, a speed-changing common carrier is connected to an input shaft through a second clutch and is selectively fixed by a second brake. A third sun gear of the speed-changing dual planetary gear is connected to the speed-reducing common ring gear of the speed-reducing dual planetary gear through a third clutch, connected to the speed-changing common carrier through a fourth clutch, and selectively to a first sun gear through a fifth clutch, and is selectively fixed through a first brake. A speed-changing common ring gear is directly connected to an output shaft.
