Important: The service shifter knob may feel slightly looser than the production part. This is a normal characteristic. Do NOT replace the entire shift control assembly for this condition.

1. Carefully remove emblem from original equipment shift control knob. Save this emblem for re-use if retaining original equipment shift control knob or for re-use on the new service shift control knob, if applicable
