01 740i - ATF for power steering fluid

I have read several posts here and it seems as if my cap says ATF on it then I am supposed to replace the fluid with synthetic ATF fluid. Does that sound correct? Is Mobil a good solution or should I go to the dealership for BMW label?

Power steering - ATF
Any Dexron/Mercon III ATF will do for the power steering if the car does not have self leveling (and the cap says ATF).

Power steering - Pentosin CHF 11S
If your car had self leveling, you would use Pentosin instead, and it would say so on the cap.

Note, the E38 automatic transmission does not use ATF. It uses Esso LT 71141 or an equivalent.

"Take to dealer to top off ATF fluid"

What's up with that. What secret is the manual talking about. Can anyone explain the tricky stuff the dealer does when topping off ATF power steering fluid? The manual won't even let us in on the exact kind we should us.

As above, if the fluid reservoir says CHF 11S on it then you will have the combined power steering and self levelling pump, referred to as a tandem pump. The reservoir is common to both systems.
