Dude take it to a garage and let them do it, pan has to come off and filter change inside of pan

Pan does not have to come off to change ATF oil. The larger plug is for refilling and the small one for draining. Make sure to see if your refill(large) plug breaks loose first or your left with an empty tranny pan with no way to fill it. Only reason you need to take the pan off is if your replacing the filter otherwise just changing or flushing the system just requires the two plugs removed.
