1. A motor vehicle transmission for an electric vehicle, comprising:
a drive input shaft configured for connection to a drive machine;
a drive output shaft; and
a first planetary gearset, a second planetary gearset, and a third planetary gearset, each of which comprises a first element, a second element, and a third element in a form, respectively, of a sun gear, a planetary web, and a ring gear;
wherein at least functionally a first shifting element, a second shifting element, and a third shifting element are provided, and wherein the first element of the first planetary gearset is connected rotationally fixed to the drive input shaft and the second element of the third planetary gearset is connected rotationally fixed to the drive output shaft;
wherein:
the third element of the first planetary gearset is immobilized,
the third element of the third planetary gearset is immobilized,
the second element of the first planetary gearset and the first element of the second planetary gearset are connected rotationally fixed to one another,
the second element of the second planetary gearset and the first element of the third planetary gearset are connected rotationally fixed to one another,
the third element of the second planetary gearset can be immobilized by means of the first shifting element and connected rotationally fixed to the drive output shaft by means of the second shifting element, and
two of the elements of the second planetary gearset can be brought into connection with one another by means of the third shifting element.
