I had mine done 11 days ago and they *attempted* a trans/diff fluid change.

I'd be interested if they changed the policy, but I doubt it. In retrospect I sure wish they had not touched mine. Can't imagine the fluid really needs changing for at least a year or 15-25k miles based on my experience with other high performance and race cars, so I sure wouldn't sweat it if they don't want to change it. Just my 2 cents.
