ABSTRACT:
A control assembly for a vehicle transmission comprising a control member pivotable about a first axis between at least two discrete positions for selecting different drive speeds of the transmission and about a second axis between two outer positions and an intermediate position for selecting forward, reverse and neutral drive conditions respectively. The assembly includes a movable barrier operable when the control member is a first of the discrete positions (to select the lowest drive speed) to permit pivotting about the second axis between the outer positions (to allow a change between the forward and reverse drive conditions) via the intermediate position and operable when the control member is in a second of the discrete positions (to select a higher drive speed) to prevent pivotting about the second axis between the outer positions (to prevent a change between the forward and reverse drive conditions) but allow pivotting about the second axis between either outer position and the intermediate position (to allow a change to the neutral drive condition) depending on the pivotal position of the control member about the second axis.
