We should change ATF and spark plug when the SAV's mileages between 80K-100K. I changed ATF and filter for my E53 at 90K miles, i should change ATF right after 80K miles instead waiting until 90K. When we drained ATF out of transmission, the fluid was so horrible, 70% of it was "metal powder", and this metal compound could kill your transmission at anytime. I did not have any tranny problems after the ATF and filter changed.

I was being facetious.
IMO, 40-50k is a MUCH better service interval for ATF. (I should take a sample when I do mine and we can stop with the speculation on change intervals.... I'll try and remember to do so. My suspicion is that Blackstone will report the fluid to be 'done' by that time- but we shall see.)
