Automobile powertrain structure including automatic transmission for transverse engine

摘要

An automotive powertrain has an engine placed within an engine compartment and oriented so that its crankshaft is directed transversely. The powertrain also has an automatic transmission placed in the engine compartment behind the engine, and a torque converter operationally coupled to the crankshaft and input shaft of the transmission. Input and are output shafts of the transmission are arranged coaxially with each other and are directed parallel to the crankshaft of the engine. A hydraulic control valve body, through which controlled hydraulic pressure is applied to the transmission so as to shift the transmission, is placed in a space defined below a horizontal plane including a top end of the transmission and behind a vertical plane including an axis of rotation of the crankshaft.
