transmission oil change interval--100k mi?
also, apparently advisors are not beginning to reco changing them as preventive maintenance since the downside is so high vs. the simple costs of changing them. particularly i hear the 7 sp could be much more demanding on the transmission/oil.

Did the job myself. Not that difficult on the 5 speed don't know about the 7 speed. But I did use the MB transmission fluid and filter. I do not substitute for mb parts.

My car now has 58k mi, i should have the ATF changed soon.
BMW had the life time ATF for their 98-02 cars, but all post 02 models now have a 100k ATF change interval. I'm not sure why BMW changed their requirement, but I think many people have complained about this lifetime fluid as a nonsense or just a marketing thing.
