ABSTRACT:
A twin clutch type speed change control system changes over the gear position by switching between a pair of clutches, to reduce the collision sound generated between a free gear and a slide member at the time of changeover of the gear position. In the twin clutch type speed change control system designed to perform gear position changeovers between odd-ordinal gear positions and even-ordinal gear positions through a process in which an engaged clutch is disengaged whereas a disengaged clutch is engaged, the formerly disengaged clutch is supplied with a minute oil pressure P1toward the clutch engaging side and is thereby preliminarily moved by a minute amount toward the clutch engaging side, at the time of changeover of the gear position.
