Certainly not from the likes of me.
The thing about ATF is different vehicle manufacturers design their transmissions to expect a very specific coefficient of friction (COF) in the ATF; regardless of the quality of the base-stock oils used for the ATF, if the COF is incorrect, the internal clutches will either grab too quickly (too high of a COF) or too slowly (too low of a COF), either way, a premature failure of the transmission is a matter of "when", not "if".
Long story short, unless a non-Honda ATF states it is certified by Honda to be 100% compatible with the Honda ATF (I don't believe there are any), then the ONLY fluid one should use in one's Honda automatic transmission is Honda ATF.
