Abstract
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).
