Here's a 35K report on the MaxLife ATF. The color was a cherry cough medicine red when it was new, and it came out looking like grape juice. The original Esso was gray so that might have something to do with it (about 10% remaining after the first ATF service).

Since Valvoline MaxLife ATF no longer meets the BMW spec, I switched to Castrol Import Multi-Vehicle ATF (available from Wally @ $5.40/qt). It didn't have the foul smell of MaxLife, and that alone, made this DIY much more enjoyable.

At 86K miles, I decided do 2 drain/refill (without a pan drop/filter change) using a total of 8 quarts. Drove the E39 about 10 miles in between the drain/refill. Thus, my tranny now has roughly 85% Castro, 13% MaxLife and 2% Esso.

Using this Harbor Freight fluid pump made filling the tranny much easier.

Still shifting smoothly!
