Abstract
A motor vehicle transmission having a continuously variable transmission ratio. The transmission includes an input-side torque converter that is optionally connectable on the output side through a first transmission stage with a predetermined gear ratio, or through a second, continuously variable transmission stage, to the output shaft of the transmission so that it transmits torque. The transmission ratio of the continuously variable transmission stage is adjustable in such a way that the rotational speed of the transmission output shaft remains constant when the transmission of torque is shifted from the first transmission stage to the second transmission stage.
