  • Patent number: 7000497
    Abstract: An adjustable gearshift assembly (10, 130) for connecting by a bracket (16) to a transmission of a motor vehicle, providing a shifter knob (12, 132) movable to a selected position relative to an elongate member (14, 144). The shifter knob (12, 132) defines an elongate inner recess (26, 146) slidably received on the elongate member (14, 144). A holder connects to the shifter knob (12, 132) to fix the shifter knob (12, 132) in a selected position. The holder selectively releases to allow the shifter knob (12, 132) to be moved to a selected second position. The holder of the first embodiment includes a ball (92) which communicates through a port (90) between one of a plurality of seats in the elongate member (14) and a slot (80) in the actuator (70). The second embodiment provides a spring plunger (158) that maintains the position of the shifter knob (132) relative to the elongate member (144). A method of selectively positioning a gearshift is disclosed.
