Shifter knob for auto
 

Does anyone know if the after market shifter knobs will work for the auto transmission? I have seen some on this site that I like but hate to order before I know they will work. http://www.andysautosport.com/chevro...t_motorsports/

I know I need one with a button so I can change gears but not sure if there is anything else I need to know.

Thanks
