ABSTRACT:
A method for operating an automatic traction drive transmission for use in motor vehicles having a first gear unit for operation in an infinitely variable mode and a second gear unit for operation in a continuously variable mode includes connecting the first gear unit to the transmission output, disconnecting the second gear unit from the first gear unit, and changing the speed ratio of the variator to produce low forward and low reverse ranges, or connecting the second gear unit to the first gear unit, disconnecting the first gear unit from the transmission output, and changing the speed ratio of the variator to produce high mode low and high forward ranges.
