Abstract
The present invention provides a means to learn and accommodate the amount of air that needs to be purged from a clutch circuit after being off for a predetermined time. The scheme helps to maintain proper control timing as necessary for good shift quality and clutch durability and further helps to minimize unnecessary delays in clutch application. Once the air has been purged, then normal control timing can be resumed.
