Abstract
An automatic transmission includes a planetary gear system which are coaxially mounted on an intermediate shaft having a first end supported by an input shaft and a second end supported by an output shaft. For example, the planetary gear system includes three planetary gear sets which are all mounted on the intermediate shaft, and an engaging device group includes a combination of first and second clutches and a first brake which are all placed around the input shaft, and a combination of second and third brakes which are placed around the planetary gear sets. The three planetary gear sets are tightly arranged, leaving little or no intervening spaces, between both ends of the intermediate shaft. No clutches and brakes are interposed among the planetary gear sets. Therefore, it is possible to decrease the length of the intermediate shaft, and to reduce gear noises by improving the flexural rigidity of the intermediate shaft.
