A torque sensor (19) is provided, which detects the input torque to the gearbox. The intermediate shaft brake and the clutch are controlled by a control unit (12), which is programmed in predetermined instances, when the gearbox is in the neutral position, the clutch is engaged and the intermediate shaft brake is released, to measure and store the torque loss from the gearbox and then to set the brake to a predetermined level and to register and store the torque increase during the setting until constant torque is attained. This is registered and stored in the control unit together with the time for the torque increase.
