I am sure that you have never seen any, but some brands of power steering fluid are dyed. Some is even red, just like ATF.

Are you being a troll or just argumentitive? Does my experience with multiple, DEALER maintained MB diesel cars with substantial records from new (my criteria for purchase) have no value?
Why dont you go check the MB Bevo site? There it clearly calls out MB 236.3 as steering gear oil. While there are some ATFs listed on there, none carry ubiquitous specifications (Dex, merc, type A, type F, etc) that you would be buying off the shelf. Manuals listed ATF for power steering. Note the bevo title below. They also list 236.2, which isn't an AT fluid for their transmissions, or per bevo, 236.3, which carries the correct nomenclature to older manuals.
MB 236.3 - Steering gear oils (ATF, Specification 236.3) - Mercedes-Benz Specifications for Operating Fluids
And while over there, check out sheet 231.1, which shows clearly on Page 3-4 that fluid 236.3 is NOT used as an ATF in MB transmissions, and is a purpose-specific steering fluid. There is no instance where 236.3 is used in ATs.

So if you want to go by the book, the ATF you are selecting may be wrong!
So why not go back and re-read exactly what I said:

What is interesting to me is that no w123 car ive ever owned has ever come to me with red ATF in the PS.
PSF is likely undyed ATF, but I've just never seen ATF in use in w123s!
I don't really care one way or another, and PSF works, as I'm sure ATF does too. ATF does have the benefit of many synthetic variants...

Which is consistent with the sheets that Ive linked to.
Now, the 1997 startek guide that is out there (which doesnt list w123 or w126 cars) says that BQ 1 46 0001 is the PS fluid, and that is what people are saying that they use from the dealer, which is a 236.3 fluid.
It does say that an approved Dex III can be used on that document (not stated specifically for 123/126), but remember that there is no Dex III on sheet 236.3. Others on here have stated that leaks have occurred when running ATF (nondescript, so likely Dex III) if you do searches for it. Ive been reading about this since 2002, so something that may be "interesting to me" is still highly relevant.
So go back to what I said.
