Start by changing the trans fluid (NOT with aftermarket fluid) , then have TCM codes cleared and see what comes back the soonest. If P0740 comes back first , plan on needing a trans. If any of the others , recommend having it serviced/diagnosed at a dealer or reputable trans shop.
sadly , this is a common problem w/ honda vans-there is a screen/filter at the top internally that clogs. more sadly honda nor anyone else has come up permanent fix for this problem. so before you go the rebuild route or new route , understand that this trans life expectancy is about 70k-100k miles
