Have used red Glyptal for years in engine building to seal the surfaces of heads and valley pan. Theory being that it speeds oil return marginally.
I had a bunch of it from a stint long ago as the opns mgr of a specialized electric forklift motor shop. Its much cheaper in bulk.
There is also an [electricly] insulating varnish that is used on the windings that requires heat that would likely work if baked on

The engine enamel would proably work. Key to any of it is meticulous prep. I have seen it used on the lower end of engines where it was blased off in sheets due to the force of oil slung at high RPM- and almost clogged the oil pickup. I dont think you would see that problem in a tranny pan though.

Powder coating would work as well, but its getting pricey locally. I ivested in an old oven and eastwood kit recently.

Cheapest/fastest option? Assuming a good prep, Id probably go with a very thin coat of hi-temp silicone like Permatex Ultra.
