PROBLEM TO BE SOLVED: To improve shift change speed performance in manual shift change in a twin clutch type transmission or the like in which a plurality of rotation power transmission systems are provided in parallel between an input shaft and an output shaft. SOLUTION: By moving a shift lever 8a to pre-shift positions PrU Pp and PrDNp, a transmission mechanism belong to the rotation power transmitting system on the clutch released side can be changed to a corresponding gear shift state without actually executing shift change. In giving an instruction for a shift change actually, sleeve driving time inside the transmission mechanism is not necessary. At timing when the shift lever 8a is moved to an up-shift position UPp or a down-shift position DNp, therefore, clutch-to-clutch operation can be executed speedily, and gear change can be completed in an early stage. Shift change speed performance in manual shift change can thus be improved. COPYRIGHT: (C)2004,JPO |
