So yeah, absolutely you COULD run something else; but then you'd never know and probably have to add a conditioner and run a risk and blah blah blah... OR...
You could just use Honda ATF to begin with. Why fuss over fluids?
Anything could go wrong with a tranny at anytime just like anything else. But the question was around what was the best fluid to use. There will always be varying opinions; but it is clear (at least to me everytime I've ever asked) that Honda fluids are preferred.
