Uhh, dude! If you grind off the bump that holds the pin in whatcha gonna do to retain the pin when you put it back together??
You don't need to, or ever want to grind that bump off. That bump that holds the pin in is on the extension housing. Worse comes to worse you take the extension housing off. But really there's no need to remove the pin at all. If fact I guarantee if you do you'll have one heck of a time getting it back together with the trans. in the car, if you can even get it back together at all. All you have to do is unscrew the band adjuster screw all the way out of the servo apply arm and using a long thin flat blade screwdriver push up against the band and the connecting strut will fall out allowing the servo apply arm to drop down out of your way. When you fix the servo you push up against the band again with the long screwdriver and slip the strut back in place.
