I checked the owner's manual since my last post. There are different types of ATF. The owner's manual specifies ATF type A. I was at the store earlier and didn't see that. A little Googling suggests that type A is an outdated fluid spec, and people are split on using Dexron/Mercon II/III or type F.
However, none of the info I mention above was from a Mercedes forum. I'm curious what folks here are actually using.
As for the differential, the owner's manual specifies 85W90. I couldn't find that at the local store, either, but at least I know I can order that if need be.
EDIT: added this copied from wikipedia. Emphasis is my own -

In the 1950s, 1960s, and 1970s, ATF contained whale oil as a friction modifier. But since whale oil would break down at higher temperatures, cars produced in the 1970s and later would not be able to use whale oil because of the higher engine coolant temperatures employed to reduce emissions and save fuel. A moratorium on whale oil at that time prevented the continued production of older ATF such as the original DEXRON formulation (Type B), and the Type A which preceded it. Vintage Chrysler products (Dodge, Plymouth, etc.) used Type A fluid, which is generally difficult to obtain now. It turns out that Type A was basically a nearly 50/50 mix of Type F (Ford) and Dexron (GM), so if you have a pre-1990 Chrysler vehicle, you can mix Type F and Dexron to get a near-match for type A. General Motors began marketing Dexron II Type C and later Dexron II Type D to replace the fluids which were made from whale oil.[10]

Don't know whether this applies to our cars.
