摘要： A vehicular automatic transmission for establishing a plurality of forward gear stages, comprising: a transmission case; an input shaft; a transmission mechanism connected to the input shaft and including a plurality of transmission elements; an output shaft connected to the transmission mechanism; first and second clutches connecting any two of the input shaft and the transmission elements individually in a driving manner; and first and second hydraulic servos for applying the first and second clutches when fed with an oil pressure. The transmission case encloses the transmission mechanism, the clutches and the hydraulic servos, and includes side walls individually at both its axial end portions. First and second bearings are arranged in the hydraulic servos between first and second pistons, as belonging to the hydraulic servos, and the first and second clutches, respectively, for allowing the relative rotations between the first and second pistons and the first and second clutches, respectively, and for transmitting the thrust forces from the first and second pistons to the first and second clutches, respectively.
