  • Patent number: 5566582
    Abstract: A selector mechanism for a vehicle transmission comprising an automatic transmission coupled to a range-change transmission having first and second ranges includes a ratio selector lever movable along three paths defined by an H-shaped gaze. The first path is defined by a first limb of the gate for shift selection in the automatic transmission with the first range of the range-change transmission selected. The second path is defined by a second limb of the gate substantially parallel with the first limb for shift selection in the automatic transmission with the second range of the range-change transmission selected and the third, transverse, path is defined by a limb of the gate transverse to the first and second limbs. Movement of the selector lever along the transverse path effects a change from one range to the other in the range-change transmission.
