I change both my AFT and diff every 30k miles since new. I had the ATF filter changed at 30/60/90, but now just doing the fluid only. I am at 152k now, and when I reach 180k, I will do the filter and gasket again. Since 90k I have been using Redline 75w-90 synthetic gear oil.

How do you know the Mobil 1 at Bav Auto is not the same as the Mobil 1 bought off the shelf.
I find it hard to believe that Bav Auto, out all places, has a "secret formula" Mobil 1 ATF.
Sounds like a load of cr@p to me...
IMO, ANY ATF from Castrol, or Mobil will be work on the E39.
The new ATF's now are newer and better.
Always evolving.
