thorromig, you wont find a aftermarket fluid recommend for an Acura/Honda differential. just go to dealer and pickup its not very expensive. i paid less than $10 a quart for mine.
Had the same problem with nissan cvt oil
However what you might be able to do, is save a few bucks ordering through ebay.
cvt nissan oil at dealer 12$/quart ; ebay like $7/quart
