  • the drive unit may be a hybrid drive with an internal combustion engine and an electric motor.
  • a transmission of a powertrain is associated with a main hydraulic pump to provide hydraulic pressure to the transmission. Furthermore, such a transmission is associated with an auxiliary hydraulic pump which, when the hydraulic pressure provided by the main hydraulic pump is insufficient, supports the main hydraulic pump to provide the required hydraulic pressure.
