Abstract
A vehicle transmission system includes an automated clutch operator. An electronic controller determines when the transmission is in a neutral condition and controls the automated clutch operator to move the clutch into a non-engaged condition. The electronic controller also determines when the vehicle engine is operating at an idle speed and causes the automated clutch operator to move the clutch into a non-engaged condition only when the engine is idling and the transmission is in a neutral condition, which eliminates neutral idle gear rattle.
