Now with the time I have spent with it I think I am narrowing it down to third gear might be the only gear that rattles. Meaning if it rattles in 3rd it will rattle a little in 4th and some in 5th. Yet if none in 3rd I do not have the problem, this theory is not 100% proven yet, and I need to spend some more time recording when it happens.
