摘要:
A transmission can be provided which achieves multiple speeds while maintaining good balance of gear ratio steps between gears by having a first clutch which selectively connects a first intermediate output member and a fourth rotating element RE4 together, a second clutch which selectively connects an input shaft and a second rotating element RE2 together, a third clutch which selectively connects the first intermediate output member and a first rotating element RE1 together, a fourth clutch which selectively connects the input shaft and the first rotating element RE1 together, a fifth clutch which selectively connects a second intermediate output member and the first rotating element RE1 together, a first brake which selectively holds the first rotating element RE1 to a transmission case, and a second brake which selectively holds the second rotating element RE2 to the transmission case.
