PROBLEM TO BE SOLVED: To reduce generation of a gear tooth hitting sound of a large level by prohibiting a preselect means from performing preselect when judged that a present operation condition is an operation condition of generating a gear tooth hitting sound of a large level when the preselect is performed. SOLUTION: A present gear stage GN, throttle opening TA and output rotating speed NT of a transmission are read in (S501). Next, whether or not it is a third speed stage is judged. As a result, in the case of NO, preselect is performed. On the other hand, in the case of YES (S503), whether or not a present operation condition is put in an area to perform preselect is judged (S509). As a result, in the case of YES, a second sleeve actuator is actuated (S510) so that a second sleeve 52 connects a second speed clutch gear G2 and a second hub to each other. In the case of NO (S509), a first sleeve 51 is actuated (S511) so as to be in an intermediate position, and is returned (S512). |
