I have a 2005 Pontiac GP Base. Usually when cold it makes an odd noise at idle park or drive that sounds like the video below at 30 and 38 or so. You can hear the sound in the background slightly and is very noticeable when I shift from park to reverse and drive to reverse (at 30-40 seconds). Also is that much movement normal for the engine?
