Here is the first sample from my 2003 BMW 330 Ci auto trans ZF 5HP19. The factory fluid is reportedly ESSO LT 71141.

Universal averages show typical wear from this type of transmission after about 25K miles on the
oil. Your oil was run 63,900 miles, which is obviously quite a bit longer than average, but metals look good.
Aluminum is most out of line, probably from wear-in at the torque converter. We don't think it was a problem
to leave this oil in place 63K miles. Your next sample should show lower metals. The trace of insolubles
(solids) is fine. The TAN read 1.5, somewhat acidic. Not all oils start at a 0.0, so it helps to do a virgin
sample to see where the TAN starts.
I think this oil could have gone the BMW suggested 100,000 miles before a change.
I just did a drain and refill, about 5 quarts this time.
I used Red Line D4 fluid and plan to sample again about 80,000 miles with another drain / refill then actually replace the filter and refill at 100,000 miles.
