Abstract

A motor vehicle transmission (1) includes a transmission housing (2) with torque converter (4) accommodated in the transmission housing (2) and a first oil guide device (9) positioned at an axial side of the torque converter (4). A housing wall (11) of the transmission housing (2) encloses the torque converter (4) radially outwardly at least in sections and has an inner surface (17) with an inner diameter configured such that a gap (13) defined by the inner surface (17) of the housing wall (11) and an outer surface (39) of the torque converter (4) is configured to convey oil from a first area (15) of the motor vehicle transmission (1) into a second area (16) of the motor vehicle transmission (1) during a rotary movement of the torque converter (4). The second area (16) is arranged above the first area (15) in an installed position of the motor vehicle transmission (1).
