Abstract

A transmission (G) for a motor vehicle includes an electric machine (EM1), a first input shaft (GW1), a second input shaft (GW2), an output shaft (GWA), three planetary gear sets (P1, P2, P3), and at least six shift elements (A, B, C, D, E, F). Different gears are implementable by selectively actuating the at least six shift elements (A, B, C, D, E, F), and different operating modes are implementable by selectively actuating the at least six shift elements (A, B, C, D, E, F) in interaction with the electric machine (EM1). A drive train for a motor vehicle with the transmission (G) and a method for operating the transmission (G) are also provided.
