The control method comprises the steps of; receiving a gear-shift command; filling with oil, always supplying the maximum possible oil flow rate, a second clutch associated with the following gear after receiving the gear-shift command; completely closing the second clutch at the maximum possible speed as soon as the oil filling ends; and completely opening a first clutch associated with the current gear A at the maximum possible speed as soon as the oil filling in the second clutch ends.
