You do have to use sealer on the engine oil pans. I don't know about 4sps, but no sealer should be used on the auto tranny gaskets. The hydraulic fluid in autos is much thinner than the oil in 4sp gear boxes.

We might drop the pan sometime to see if the gasket is bad or not.

It's a 50 year old car known for leaking fluids from everywhere. Just approach your rebuild as though you have to regasket and seal EVERYTHING. But, does it mean that you have to do it right now? No, leaks are just leaks that are annoying and messy, but unless they're catastrophic they can usually wait to be dealt with later. Your primary focus on your car should be restoring the body or getting it stable, safe, and presentable. That means stripping the car of parts and engine and focussing on clean up, bodywork, and paint. The body is EVERYTHING on these cars. Once you have a decent body, THEN you start worrying about parts fix up. Since you'll have removed the engine and tranny to do the body, then you might as well regasket and seal the engine and tranny, plus axles and stuff.
