If you’re ever in a hurry to get somewhere, and don’t have time to change the shift knob on your automatic car, there are a few ways to do it without having to go through the hassle of changing the entire car. One way is to use a vacuum cleaner with the hose attachment. Put the vacuum cleaner tube over the shift knob and turn it around so that the suction is on top of the knob. Turn off the vacuum cleaner and remove the shift knob from its position.
