Scott T. Ibbotson July 9, 2015 at 8:31 am Shifter control knob Freeautomechanic July 10, 2015 at 2:14 pm Push down on the ring on top of the shift boot. It should slide down. Next there is a clip at the bottom of the shift knob. It was under that ring you pulled down. Pull that clip off. The shift knob should then pull off. Comments are closed.
