Abstract
A method reduces the noise in the drive train of a motor vehicle having an automatic transmission or a manual transmission with a controllable oil pressure supply and/or automatic starting clutch. An engine sided drive unit is connected to the transmission input shaft by way of a spline connection, wherein noises in the drive train are caused by a clearance fit in the spline connection between the engine sided drive unit and the transmission input shaft. The transmission control is adapted for reducing the noise when in neutral.
