.....added a quart of new ATF then added 6 oz of Archoil AR9100 fluid
Archoil says to use 1.8 oz of Archoil in that much engine oil. Could be they've seen foaming with using over 3 times as much like you did. In high-RPM spinning gears, foaming can be an issue. For example, pro racers don't dare deviate from a fully formulated & tested ("track record" is everything with pit crews) oil, engine or gearbox, out of concern they spark foaming (aeration) at high speed.
Tempting to experiment with different stuff in the fluid though. You just don't know what the final result will be, as it must compete with the regular ATF fluid for surface action. I got crazy a few years back & put in some polymer esters into a differential once, just a bit. I only imagined it might make a difference, who knows?
After a year, maybe check the magnets for iron as the only real measure we have of how much Archoil or anything else might work. Even that is subject to many variables, although one use on here (was it Estomax?) had clean magnets after a few thou miles using premium Redline D6 fluid. Some evidence the premium sauce makes a difference anyway!
