FIELD: motor vehicle industry.

SUBSTANCE: invention relates to the vehicles. Method for operating a vehicle driveline comprises activating an electrically driven transmission pump in response to a request to stop an engine and adjusting a position of a hydraulically operated screw driven clutch gap filling device via fluid provided via the electrically driven transmission pump. Method also includes reducing the clutch gap by adjusting the position of the hydraulically operated screw driven clutch gap filling device, which is located inside the clutch, depending on the result of estimating the length of time between gear changes in the transmission.

EFFECT: reduced consumption of transmission fluid.
