Hi!
I'm new to the forum and a new X5 owner. I want to change the transmission fluid in my 2001 4.4l with 70k miles and want to know what the recommended fluid is. I can sum up my feelings on BMW's 'lifetime' fluid with a series of four-letter words.
I've seen that Bavarian Autosport sells an Esso brand fluid for $18/liter, which seems way excessive. Does Redline make something that is acceptable?

And what kind of fluid does the transfer case use?
