ABSTRACT:
An automatic transmission for a motor vehicle includes a layshaft gearset (38, 40), a planetary gearset (96), two concentrically arranged planetary gear units (44, 54), certain elements of which are continually interconnected, friction clutches (76, 78), brake band (46), friction brakes (92, 106), and overrunning coupling (80). The input shaft of the transmission is adapted to drive elements of the planetary gear units through the layshaft gearset and planetary gearset. A single gear wheel (57) is formed with the ring gear (48) of the first gear unit and the sun gear (56) of the second gear unit. Carriers (50, 60) of the gear units are connected to an output shaft (64), which drives output gearing (66, 68) and a differential mechanism (70).
