So I was passively doing some more digging on this fluid for my AS69RC trans. Again the usual suspects to use are Mobil 3309. I was communicating with Aisin on the matter but they have not been very forthcoming with my questions. Apparently besides the 3309, my trans can also use their Aisin ATF-OT4. Other than it is made by various suppliers and blenders, that was all the information I have received. Now my next step is to see what other transmissions can use this fluid in another attempt to cross check compatibility.
