Abstract:
An embodiment provides a method shifting a multispeed transmission. The multispeed transmission includes multiple gear paths having alternating speed ratios and a plurality of shift members. Each shift member is selectively moveable to engage a speed ratio of the transmission. The method includes directing a shift finger to contact a first shift member, moving the first shift member generally in a first generally orthogonal direction to engage a first gear, and moving the shift finger in a second generally orthogonal direction to an intermediate configuration. The shift finger will not contact a selector rail when moved in the first direction when the shift finger is in the intermediate configuration. The method also includes moving the shift finger generally in the second generally orthogonal direction to a second engaged configuration. The shift finger will contact a second shift member when moved in the first direction when the shift finger is in the second engaged configuration.
