ABSTRACT:
A shifter for a vehicle transmission comprises a cable aligned along an axis generally parallel to the steering column of the vehicle by a support bracket, an actuator lever pivotally secured to the support bracket for pivotal movement about a first pivot axis, a control lever whose first end is secured for pivotal movement coaxial with and corresponding to pivotal movement of the actuator so that a second end of the control lever traverses an arcuate path about the first axis, and a coupling for securing an end of the cable to the second end of the control along the longitudinal axis of the cable. The first pivot axis is aligned at an obtuse angle with respect to the second axis so that displacement of the control lever along the arcuate path is in a plane substantially coincident to the longitudinal axis of the cable. In the preferred embodiment, angular alignment between the first pivot axis and the second pivot axis is predetermined to contribute to alignment of the actuator lever toward a substantially radial position with respect to the longitudinal axis of the cable so as to simulate conventional shifter operation. Such simulated alignment of the actuator lever is also provided by a bend formed in the shift lever so that the distal end of the shift lever is positioned substantially radially with respect to the longitudinal axis of the cable.
