HELP! transmission case repair?

No welding. See, what nobody is considering (except ME) is that that's an INLET hole. It has to stay CLEAN. And welding will fry that gasket next to it. Just do like I said and cut it off and re-tap it and install the original fitting, or go look at Lowe's broad selection of brass fittings that could be used to extend it out from the case. This isn't really a big deal to fix. Worst case scenario, you make mess of the hole and have to use JB weld to seal it up around the new fitting. NUMBER ONE is to cram something in there FIRST that you can pull back out when you're done.

You think you're the only one that knows it's an open passage into the transmission? C'mon man.

By far the worst part of that operation for "keeping it clean" will be retapping that hole like you suggest. In reality the thing should be disassembled for any kind of repair. But this is aluminum welding not MIG with flux core, spatter isn't an issue. And not frying that gasket shouldn't be a problem for any welder capable of that repair. Aluminum melts at half the temperature of steel, and the gasket itself should be able to withstand a couple hundred degrees. The gasket is the easy part. Still might not find a shop that will weld on anything other than a bare case.

Using JB weld on a threaded inlet that sees pressure and will be attached to a line that's going to vibrate is just setting the stage for the day you're going to be sitting on the side of the road covered in transmission fluid waiting for a tow.
