No, the fluids are NOT the same. Like a lot of things in life, just because something has the same name or title on it as something else doesn't mean it's the same. Search the forum, ask anyone on here, or ask your dealer(s) and they will tell you the same. With few exceptions, Honda fluids are best for Honda cars, at least in stock form.

And no, a flush is NOT the same thing as a change. A dealer should be telling you that you do not want a flush but only a change. There is a difference and you do not ever want to flush your tranny. You could potentially jack it all up by doing so...
