Dex 2 is readily available from shell its called donax. There's a synthetic one and a mineral, and is widely used in plant and commercial applications. I've been using it for years, in carltons and now omega, gearboxes and power steering.

Having just read through this: https://en.wikipedia.org/wiki/DEXRON#Dexron-VI which describes the development of Dexron I am none the wiser. Which version of Dex 2 are the current products that are available to buy?

To much information, you are suffering from. Go to a lokal hydraulic hose repair, eg(pirtek) or agricultural tractor place, dex 2 is still widely used.

But did you read this paragraph BG?

 Dexron-II, IID and IIE

Dexron-II was introduced in 1972 with alternative friction modifiers such as Jojoba oil. However, it caused problems with corrosion-prone solder in GM's transmission fluid coolers;[2] accordingly, corrosion inhibitors were added to the product. The resultant fluid, released in 1975, was called Dexron-IID. However, the corrosion inhibitor made the new fluid hygroscopic, which while it was not a major problem in automatic transmissions, made Dexron IID unsuitable for other hydraulic systems in which it was commonly used.[2] A further reformulation to address excessive hygroscopicity was named Dexron-IIE (GM Spec GM6137M).

e.g.  Power steering, so my question remains, what version of Dex2 is available?  If Dex11E, that's OK, but not Dex 11D, unless a programme of regular fluid changes, as adopted by some, is instituted. It seems, according to Wiki, that GM no longer endorses the spec of anything less than Dex V1

Any DII should be fine.  I use the cheap shite that Hellfrauds sell for about £4 (trade) for a small bottle. Mainly for convenience rather than anything else.

The dex2 you are buying will be the last spec, before it was superceded by dex3,. I use spirax s2 atf, exceeds and meets all gm,mb and voith specs.
Or as TB said just go to Halfords and buy there atf fluid, which will have spec available on line,.

Just checked in my fastidiously kept, accurate excel file of my car's service history, as sadly all it states is 'Dexron 2' however, I know I bought it from a euro car parts depot place, while we were on a weekend away. It was £4.80. The best bit was, given the guy had never seen me before, I wasn't local, I thought I'd chance my arm and say 'what's trade on that?' - which he answered 'uh, that is trade, mate'! whatever it was about by voice/appearance/cleanliness said I was a mechanic!?! 

If the bottle's still kicking around I'll try and find it, but TB's price is about right. I don't really think there's such a thing as 'poor quality' atf, vs 'good quality' the only difference is price.

I've just checked the spec of Dex11 at CAF, or whatever they are now called. It states" Complies with Dex11D and Dex11E.
Given the statement in Wiki above, this means that it is both hygroscopic and non-hygroscopic at the same time. Go figure.
I think I'll stick to the GM DexV1 which GM specifies for the PSF.

[Diamond Black Geezer]

OOF recommends sticking with Dex VI, however, as I found out, there'd been all manner of different 'Dex's' put in my PAS system prior to my ownership, whatever was hanging around work/dregs left in a bottle etc it seems, and there are no leaks to be seen on my PAS system. So we'll see for a long-term test on yours
