Maybe try ATF RTV?

Had to look that one up, never heard of it. That’s a possibility.
I would put a manual in it at this point!
So what’s this square cut o ring you are talking about?
I second this!
Mopar makes one that you can basically apply to wet ATF and it still seals, always amazed me. Looks like its been replaced by this:
@fastazz81 may be able to shed some light as to whether its as good as the original.
I think that I am thinking of the transmission side.
There is a square cut o ring on the trans side of a TH400/4L80 adapter.....

Called Greg’s shop they said the trans is normal to do that. What they recommended was is a paper gasket with a light coating of rtv. They said overtime trans fluid would eat it the rtv.
Digging through my parts bin I found these. Which would you use?
Very curious as to why some torque converters drain down and drip, and others don't.
Mine can sit for a month or more and no leaks. Though the engine and trans are factory angle. Only np205 drips gear oil, AFAIK no atf in that t case.

Either should work light skim of rtv both sides. Attention to the stud holes
That is what I have.
I don't like anything fluid like, it makes a mess
Confirmed the case is flat and so is the adapter housing.
This thing just hates me I guess and wants to be a 2wd truck!

The one on the left seems thicker, I would use the thicker for more flexibility
I forgot this truck was a 2wd, no wonder none of this is working 
That's not a good thing with aluminum, too easy to remove material and not even know it.
Are the studs still tight when you go to fix it?
I agree with the guys, it shouldn't leak even if you park it on an uphill.
It's hard to tell with all the silicone, but shouldn't there be a pilot diameter to keep it centered? I see you have the pilot on the back of the trans case, but I don't see a pilot on the adaptor, is it flat? If you have nothing holding it on center I don't see how it would stay put and seal. Please post a picture of the adaptor surface that contacts the transmission.

Yes that is correct, it indexes into the trans case with a lip
Look here in your picture...there are two pilots...
And it both has to center itself, and seal within that small area. I would guess that maybe your trans is setup to pilot on the inner ID, and then have an o-ring on the outer ID, there is basically no room for a gasket.
Like this piece, pilot on the inside, then o-ring seal...thats not hte piece, too large of a gap between the bolt pattern and the seal, but you get the idea...
