Abstract

An automatic transmission of a motor vehicle driven by an internal combustion engine with a transmission oil circuit, a main oil pump, mechanically driven by a combustion engine, and an auxiliary oil pump (1) that can be electrically driven and is located inside an oil sump (4). It is proposed that the auxiliary oil pump (1) is arranged transversely with respect to the travel direction (x) of the motor vehicle.
