Transmission for a drive train of a vehicle

A transmission for a power train of a vehicle includes an input shaft, two output shafts, and a differential arranged between the two output shafts. The differential includes two planetary gear sets, which include multiple gear set elements. A first output torque is at least indirectly transmittable onto the first output shaft by the first planetary gear set.
