Anyhow, even today, the BMW dealers balk about changing tranny fluid, but I would probably use BMW specific ATF fluid.
Mind you, I had an automatic tranny 325is with ATF fluid flush every 30K miles and guess what, the tranny lasted till 295K miles with no problems.

Congrats on the long life of your X, gotta love the I6.
I'm an advocate of tranny flushes myself, hopefully they keep lasting you as well.
