The Spicer Study from 2007 converts some anecdotal information into numbers which I prefer. It's an excellent report on the ability of so called fuel additives to accomplish product claims.
The study didn't look at ATF, but it did look at used engine oil and 2 cycle oil.
As noted, the engine manufacturers don't recommend any additives. But Cummins has developed an entire product line within their company just for fuel improvement products.
There is no recommendation from me on using additives and as you've read there are differently schools of thought on using them. But if you need scientific, statistical data, then this study might be relevant to your decisions.
Based on the information in this study, I use bio-diesel where I can and pick something else when bio is not available.
