Don't get me started on rattles an squeaks
Have had all kinds on the FL Elite while most are now cured a few remain here's a few over the years I've found.... Centre air vents, rear seat belts, arm rest, steering column, drivers air vent/housing, transmission handle/sports mode button, glovebox, creaking rubber when windy passenger drivers door area, cd multi-changer metal plate something there rattles and it's not the plastic 4-stack holder, ummm that's about it
... Saying that I'm ultra fussy about rattles so I'm told anyway 
How did you stop the transmission handle?
Didn't get round to sorting that out and tbh, Anyway it seems to have got better over time.
This stuff came in handy for most rattles...
