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).

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.

A drive train unit (HY, G) for a motor vehicle includes a first shaft (TW), a second shaft (PW), and a third shaft (AN). The first shaft (TW) is rotatably mounted at an inner diameter of the second shaft (PW) with a first bearing (L). The second shaft (PW) is rotatably mounted at an inner diameter of the third shaft (AN) with a second bearing (L, L). A lube oil feed to the first bearing (L) and the second bearing (L, L) takes place through a bore hole (B) arranged in the first shaft (TW). An oil baffle chamber (S) is formed at an inner surface of the second shaft (PW) and includes a first outflow (S) and a second outflow (S). A drive train for a motor vehicle may include such a drive train unit (HY, G).
