There has been much debate about this on the MB forums,some say ok but most posts I have seen say stick with the MB stuff(fuchs or shell). I just purchased Fuchs Titan 4134 which was developed for the newer 7 speed trannies but is backwards compatible. Meets 236.14 approval. Will post review. Supposed to get it on Monday. If you have more than 40K on your tranny I would recommend changing the fluid and filter asap.

I believe it's ATF-4.
