Abstract
A vehicle transmission includes first and second main shafts that enable switching of power transmission from an engine; a counter shaft connected to a drive wheel; and gear trains with a plurality of shift stages provided between each of the first and second main shafts and the counter shaft. The vehicle transmission also includes shifters which switch between engagement with and disengagement from a gear constituting part of each of the gear trains so as to switch the established states of the gear trains, and to prevent, during running at the most frequently used shift stage, the occurrence of gear rattle produced by a gear train other than the gear train with such a shift stage. With this configuration, in the running state of using a particular gear train with the highest frequency of the established states among the gear trains, the gear trains, excluding the particular gear train, are in the non-established state.
