I'm looking at doing an ATF drain and refill on my 2011 35d. Looks like it uses either OEM ZF Lifeguard 6 (around $20-24/qt online; partially synthetic) or the genuine BMW fluid (very overpriced at around $40/qt). However, it appears that Febi 34608 ATF ($10/qt online at rmeuropean.com) is certified for the required Shell M-1375.4 spec (per literature was created specifically for the 6 speed transmissions). Not sure if it's partial or fully synthetic. I am looking at ordering 6 liters and will probably do a drain and fill every 40k or so.

Anyone with direct experience using Febi 34608 ATF? Of note, Pentosin ATF1 (a fully synthetic ATF; ~$18/qt) is also approved based on approval spec sheets (ZF TE-ML 11B and Shell M-1375.4)--looks like a great option as well.
