raceyBMW,
You may already have this data for specs of Pentosin ATF-1:

But that was back in 2003 when it was also known as ESSO LT 71 141. Pentosin, as you know, claims it can sub Shell 1375.4, but I haven't found a newer spec.
I thought the following might be interesting. Some further internet searching showed a comment made to a Jag inquirer with regard to his ZF 6AT. The discussion centered around whether Ford Mercon V could be used in the ZF. This is supposedly the reply from the ZF rep. (of course, this is all unsubstantiated):

Venelin,
I can not advise the use of the Ford fluid in your Jag. I am not clear as to the outcome of its use. ZF currently has several fluids used for various 6HPapplications. A good example is Audi who recommends fluids by vehicle model not transmission model. This may be due to the demands of the specific vehicle such as smooth shifting VS performance orientated driving requiring faster shifts and better heat control. The friction coefficient of the fluid is programmed into the transmission controller. Changing fluid type will affect the calculation and ultimately drivability. This in a worst case scenario could lead to transmission failure. The correct ZF or Jag fluid is a small price to pay in comparison.

I Bolded the statement that I find relevant to other discussions that I've read where the ZF tranny adapts the way it shifts over time due to mileage, usage, and calculated breakdown of its oil.
