Punch/Hammer <- major PITA.
Air chisel with a punch attachment. <- takes 2 seconds with this.
Several people are going to tell you to leave it connected. <- unweildy
I rigged something a long time ago with a HUGE pair of vise grips, a 14mm deep-welled socket, and a nail that was cut-in-half.
Get yourself an air chisel, and save yourself the greif. Honda recommends against re-using that pin even though there's a clip that holds it in place, and it's like $7. Something about the shifter getting sloppy with too much play. They call it a roll pin.
