Abstract

A transmission (G) for a motor vehicle includes a housing (GG), a gear set (RS) arranged within the housing (GG), an electric machine (EM), and a power electronics module (LE). The power electronics module (LE) includes a carrier element (S), a DC voltage terminal (DC), an inverter (INV), and an AC voltage terminal (AC). The housing (GG) includes, on an outer wall (GGA), a region (GGE) for accommodating the power electronics module (LE), which is closable with the carrier element (S) of the power electronics module (LE). The region (GGE) of the housing (GG) and an inner side (SI) of the carrier element (S) form a dry space (TR) for accommodating the inverter (INV), which is attached to the carrier element (S). The region (GGE) of the housing (GG) at least partially separates the gear set (RS) from the dry space (TR).
