Abstract
A method of controlling a dual clutch transmission (DCT) for a vehicle includes steps to reduce objectionable noise present during particular driving conditions and when the vehicle is operated using certain driving habits. A DCT engages at least two gear ratios at a time; one gear ratio for the current desired gear and a second gear ratio for the next likely gear. The method detects when conditions are favorable for the objectionable noise and takes action to remove the cause of the objectionable noise.
