The shift indicator in most cars sits at the bottom of the instrument cluster, but sometimes may be found in the center console between the car seats. The sfift indicator is often called a  "Prindle" adding a vowel to the letters PRNDL. PRNDL stands for Park, Reverse, Neutral, Drive and Low. Some cars though may use numbers for the gears like the one above, PRD321. Mechanical ones like the one to the left don't fail often, but the electronic ones often do.
