ABSTRACT:
An automatic transmission including: a torque converter; a torque converter housing; an oil pump; an overdrive gear mechanism; an overdrive case; an underdrive gear mechanism; a transmission case for the underdrive gear mechanism; an oil pan under the underdrive gear mechanism; and a hydraulic control device controlling a hydraulic pressure to be delivered to the overdrive and underdrive gear mechanisms. In this automatic transmission, the overdrive case is formed with a first passage connected to an inlet port of the oil pump, a second passage connected to a discharge port of the oil pump, a third passage connected to an inlet port of the torque converter, and a fourth passage connected to an outlet port of the torque converter, with the second, third and fourth passages being connected to the hydraulic control device.
