Gotcha,

I realize Mercedes, like BMW states 80-100k mile service intervals as well, but some of the guys on the BMW boards like to change their fluid every 30k miles for maximum trans longevity.

What concerns me a little more is that I've read (and recently saw one example here) that the SLK/XFire has a known issue with a trans seal going bad and fluid leaking out. Just wanted to see if there was any way to check the level or top off the fluid.

I'll leave it alone in that case.

Thanks!
