Abstract

The present invention relates to a lubrication system (8) for a gearbox (3) which is arranged in a motor vehicle (1). The lubrication system comprises a first lubrication circuit (9) with a mechanical pump (12) delivering lubricant to the gearbox (3) and a second lubrication circuit (9) with an electric pump delivering lubricant to the gearbox (3). The mechanical pump (12) is driven by a component in a powertrain of the vehicle via a mechanical transmission (13). The mechanical transmission (13) comprises a coupling member (15) movably arranged between a connected state in which it transfers a driving force from said component (14) to the mechanical pump (12) and a disconnected state in which it breaks the transfer of driving force from the component (14) to the mechanical pump (12). A control unit (26) is configured to move the coupling member (15) to the disconnected state when the electric pump (21) has capacity to deliver a required lubricant flow to the gearbox (3).
