Abstract
A vehicular automatic transmission for establishing a plurality of forward gear stages, includes: 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 at opposite ends of the transmission mechanism and drivably connecting the input shaft with at least one of the transmission elements; and first and second hydraulic servos for applying the first and second clutches responsive to feed of an oil pressure. The transmission case encloses the transmission mechanism, the clutches and the hydraulic servos, and includes axial end walls forming cylinders for the hydraulic servos. First and second bearings are arranged between the pistons of the hydraulic servos and the first and second clutches, respectively, for allowing the relative rotation between the pistons and the clutches and for transmitting the thrust forces from the pistons to the respective clutches.
