A method of suppressing gear rattle

A method of suppressing gear noise in a dual clutch transmission (10) for a motor vehicle with the input shafts (12, 14) and two output shafts (16, 18) between which fixed gears and synchronous clutches (28) shiftable Loszahnrader are provided, and with at least two of the two output shafts (16, 18) via the switchable synchromesh clutches (28) acting, wet-running multi-plate clutches (32, 34), which alternately control a flow of force through the gear drives, wherein the disk clutches (32, 34) are passed through to their cooling and wear minimization with oil , characterized in that in the normal case, the two multi-plate clutches (32, 34) are supplied to a degree with oil, in which no drag torque in the open or opened in two multi-disk clutches (32, 34) occurs, and that (under defined operating conditions of the transmission 10) each non-activated, the flow rate of oil at least to the, open Lamel lenkupplung (32, 34) is increased such that at the open disk clutch (32, 34) a defined drag torque occurs.
