1. A method, comprising:
responsive to determination of a skip shift condition, controlling a rotational position of a first barrel cam of a shift assembly of a transmission around a rotational axis in a first direction via a first motor to disengage one gear wherein the skip shift condition is a condition in which a controller commands the shift assembly to adjust the transmission from a current gear engagement to a different gear engagement in a non-sequential order; and
controlling a rotational position of a second barrel cam of the shift assembly around the rotational axis in a second direction that is opposite the first direction via a second motor to engage another gear that is not consecutive with the one gear, independent of the rotational position of the first barrel cam;
wherein the steps of controlling the rotational position of the first barrel cam and the second barrel cam occur at an overlapping time; and
wherein the first barrel cam includes a first cam track and the second barrel cam includes a second cam track.
