A transmission arrangement (16) for a motor vehicle drive train (10) includes a first input shaft (24) connected or connectable to an internal combustion engine (12), a second input shaft (26) arranged coaxially to the first input shaft (24), an output shaft connected to the first input shaft (24) via a first plurality of engageable first gear-step gear sets (38, 42, 44) and connected to the second input shaft (26) via a second plurality of engageable second gear-step gear sets (36, 52), a first electric machine (56) connected to the second input shaft (26), a second electric machine (60) connected to the first input shaft (24), and a first clutch (K1) via which the first input shaft (24) and the second input shaft (26) are connectable to each other. The second gear-step gear sets include two alternately engageable gear-step gear sets (36, 52), via each of which an electric motor-driven operation is establishable by the first electric machine (56). The transmission arrangement (16) is configured such that an internal combustion engine-driven operation is establishable via one (36) of the two alternately engageable gear-step gear sets (36, 52) when the first clutch (K1) is engaged.
