I also like a plug bc i put a magnetized one in there which i feel helps remove metallic particles plus allows me to monitor things. i use permatex black ultra on gasket surfaces such as oil pans, drain plugs, water pumps, etc and have never had anything leak. I used a fumoto valve for the first time on our new challenger and realized up front i was giving up a magnet and making the drain hole a bit smaller, but i really like that too and would do it again. I got the one with a bib to attach a clear hose for draining, changing that oil is a snap especially with the oil filter in top of engine bay.
transmission fluid and filter change?

The OEM pan should have had a magnet stuck to the inside.
Silicone sealer has NO PLACE on a drain plug or a trans pan gasket surface. In fact, RTV Silicone should never be used to "seal" a gasket. It should be used INSTEAD of a gasket, or to seal the seam between a gasket and a rubber seal, if it's used at all. There's a dozen decent gasket sealers readily available--Gasgacinch, High Tack, Copper Coat, Indian Head, Permatex #1, #2, and #3, etc. Use any one of those instead of damned RTV Silicone.

yes that magnet was cleaned and put in new pan. i just like xtra magnets, i think i put 2 in the bottom of my deep pan in my other truck along with magnetic plug.
i have literally never had any trouble ever with ultra black permatex, only when not using it. good info with the better gasket sealers, i will stock up on those and use them next time probably permatex 1 2 or 3 i will look more into that!
I use a copper washer as gasket on the drain plugs I've added: no leaks ever. The Japanese used silicone on their transmission pans, not that i'm a fan, but they rarely leak. Have seen it on Subaru, Toyota, Jeep. I use a regular gasket when I service them as I am not a big fan of sillicone myself (usually 24 hour cure time). As for reusable gaskets I like lube locker LubeLocker.
