A transmission assembly for a motor vehicle includes a transmission housing, a spur gearing in the housing having an input gear and an output gear, which are connected to one another, a differential gearing in the housing, wherein the differential gearing has a differential cage connected to the output gear for conjoint rotation, and numerous compensating gears rotatably supported in the cage, a sump that defines a fluid level in the transmission housing when the installed transmission assembly is stationary, and a shielding shell in the transmission housing, which surrounds the output gear and the differential cage, at least below the fluid level, to shield them against the sump, wherein the shell has a first channel, wherein fluid in the shell can be conveyed from the shell along the first channel to at least one area in the transmission assembly.
