I did my ATF flush through fill plug using that same kind of funnel:
I stacked my 12, 6 and 3" extensions, and with a 30" breaker bar, the fill plug popped right off. Fill plug gasket is totally reusable. It's the drain plug crush washer that you are supposed to replace.
At $9 for a 20-pack, not a problem. If the fill plug gets loose, no big deal. Drain plug working loose while you are on the road.... ouch.
