Topped it up, and my rev bounces have stabilized at idle...give it a try if you've had similar issues!
I have had a bad idle bounce since 1k miles that magically the dealer was never able to replicate. I'm sure the fluid level has been checked before, but I might as well take a look when I get home tonight. I'm willing to try just about anything.
