I replaced the fluid in my 2001 @ 108K miles. I drove it to 126K miles before trading it in on my current X5. Never had a single problem with the transmission. My opinion is there's no such thing as a lifetime fluid and therefore feel replacing it at 100K miles is more than reasonable.

I've read the opposing points of view but, aside from being theoretical in nature, I have not seen any statistics to show a correlation with replacing the transmission fluid in a high mileage X5 and failure of the transmission. My indy mechanic, who has been working on german vehicles for decades, has not observed any correlation either.

Now you have a million and one opinions
