Can you put an angle finder on the pan and tell me if it’s flat?
Well something is definitly wrong, because none of my 241’s or 208’s leak. Have you tried the stock gasket?
The tcase is fine it’s the seal between the trans and tcase that eats up. Would you be able to put an angle finder on the trans pan as well to see where it’s at? I wonder if mine is pointed down adding to the fact.
Wouldn’t it be hilarious if I had the wrong dipstick and have been overfilling it for 9 years?
No, I understand where youre talking about. I meant that spot. You should be able to over fill it by gallons and it shouldnt leak.The tcase is fine it’s the seal between the trans and tcase that eats up.

I see what you mean, I’ll give Greg’s shop a call tomorrow and see what they say.
If you take a look at this picture in the bottom
You can see the hole that goes into the pan.

Is there 3 tabs next to the hole, like there's supposed to be a plug in there?
I mean, I could, but I don't always park on a flat surface, and it never leaks. Also, I overfill it by at least a quart so that on really steep climbs I don't run low on fluid. I don't think this is your issue.
Something is wrong with your mating surfaces. I use a very light coat of right stuff and don't have a problem unless the bolts get loose.
Nope
I’ll double check tomorrow but it has a new advanced adapters adapter housing and this is the 2nd tcase it has had in it with the same results.
Are they parallel to each other? My th350 and np208 have a similar adapter housing and none of those issues. It leaked but it was a drop or two after sitting for a month. Nothing like what you are dealing with.
Wait, isnt this supposed to have a square cut o-ring?
Not sure what you’re saying. Tcase is a 91 np241
Check this thread out, same issue
4L60E Transmission Rear Seal - LS1TECH - Camaro and Firebird Forum Discussion
Automatic Transmission - 4L60E Transmission Rear Seal - Does anyone know why my transmission might be overflowing into the connection between it and the NP2 transfer case? It has been leaking fluid for some time and it seems I haven't solved the problem while doing the rebuild. I had replaced...

I am pretty sure mine does.
That area is supposed to have fluid and that seal is supposed to keep it in.
The only time mine leaks is when the bolts would lose enough to separate and have a gap
When I had a clocking ring with my NP208 and 241, i had to be meticulous about putting a bead of RTV around each mounting hole on the face of the transfer case. In the picture below I can see what appears to be bare metal around a couple of the mounting holes.
If I was you, I'd put studs in the 241 so you're not messing around lining things up which results in the bead of RTV getting wiped off in places. Just set it up there and push into place.
I think a gasket skimmed with RTV on both sides might work. But from what I remember, the face of the tcase is very thin around the mounting holes so a gasket has to be perfectly made.

And I'm not a fan of using a wire wheel on aluminum.
Try ditching the silicone and using the oem gasket.
I would put a lite coat of silicone on the gasket, just in case there's any pits in the aluminum. I'm also wondering if the advance adapters piece is the issue....
It did it with the last adapter also, it seems when I park the truck for some time it just gets eat up.
Already studded, some of the rtv is on the tcase side when I pulled it, some of it peeled with it. Doing a “feel test” the silicone definitely failed as it doesn’t even feel like right stuff
I have tried it, ended up with the same results but much quicker of a leak.
