904 Leaking. What to check first?

I’m in the process of “resurrecting” a 1976 Dart. I’m quite comfortable with the engine at this point( fixed an overheating issue, plugs, timing).

Attached are pictures of what I want to tackle next. It’s leaking transmission fluid really bad. I was thinking of starting at the transmission pan gasket, lowering it, cleaning all the fluid off, a Felpro gasket and reattaching and torquing to spec. I also think the plug where the neutral safety switch (I think that’s what it is via the diagrams) is leaking.

I believe the other leak at the front is an easy fix. Someone put three clamps on a rubber hose running into the transmission cooler inside the radiator.

Where could you offer advice to start? Thanks.
