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

Motor vehicle transmission with a torque converter

An automatic transmission (1) includes a transmission housing, a hydrodynamic torque converter (5), a first brake, a second brake, an intermediate plate (6) fixedly connected to the transmission housing and with ducts for supplying the hydrodynamic torque converter (5) and the two brakes (A, B) with oil. An oil guide shell (7) is arranged between the hydrodynamic torque converter (5) and the intermediate plate (6). Oil coming from the two brakes sinks via oil ducts (39.1, 39.2, 39.3) in the transmission housing and the intermediate plate (6) via the inflow opening (40) in the oil guide shell (7). The hydrodynamic torque converter (5), via rotation, conveys the oil to the elevated oil ejection opening in the oil guide shell (7), from where the oil sinks into the tank (8) via a gap (52) delimited by the oil guide shell (7) and the intermediate plate (6).

Automatic transmission for a motor vehicle

A lubricant guide shell () for includes a first, radially extending section (), which is provided for being situated axially opposite an end face () of a torque converter () in an installed state of the lubricant guide shell (). The first section () transitions radially outwardly into a second, axially extending section (), which, in the installed state of the lubricant guide shell (), is configured for axially at least partially and radially outwardly encompassing the torque converter starting from the first section (). The first section () as well as the second section () are configured to be completely circumferential.
