ABSTRACT:
An automatic transmission with overdrive, 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; and an oil pan. In this automatic transmission, the overdrive gear mechanism is positioned between the torque converter and the underdrive gear mechanism. An exhaust passage is positioned in a lower portion of the overdrive case in side-by-side relationship to an intake passage adapted to introduce oil from the oil pan to the oil pump. As a result, oil is circulated from the oil pump to the hydraulic control device, then to the underdrive gear mechanism and the overdrive gear mechanism and then to the oil pan back to the oil pump.
