Abstract:
When an engine is restarted after a predetermined period of being stopped oil is supplied to a clutch pack for a 2-3 and/or 3-4 shift while a transmission is engaged in the first speed for the first time since starting. The amount of oil drained during the predetermined period of being stopped is complemented in advance such that shift quality of a first 2-3 and/or 3-4 shift is enhanced.
