<p>The automatic transmission casing includes a first case portion (12) in which a torque converter is housed, a second case portion (13) in which a transmission gear mechanism is housed being arranged in a series with the first case portion, and a third case portion (D) in which a differential mechanism is housed being disposed extending in a transverse direction against the first and second case portions. The automatic transmission casing is further provided with a partition or wall member (14) being disposed between the first and second case portions and with an reinforcement rib (112) connecting the third case portion to the first or second case portion. Switching or shifting of power transmission pathways of the transmission gear mechanism is effected by operation of hydraulic actuators, and a plurality of accumulators to be used for prevention against a transmission shock are connected to the actuators and arranged separately in the partition member and the reinforcement rib.</p> |
