Abstract
An automatic transmission includes first and second planetary gear sets, and a third planetary gear set which is closer to an output end of the transmission, and which is smaller in diameter than the first and second gear sets. One brake is disposed around the first and second planetary gear sets, and another brake has a pack of brake plates surrounding the smaller third planetary gear set. A transmission case is therefore made gradually smaller toward the output end. This planetary gear system makes it possible to arrange the brakes very compactly, and the tapered transmission case improves the rigidity of the automatic transmission.
