You are correct that's where the level should be when running.
If I pull the slip yoke out of my TH400's 2wd tail housing, should I lose a little fluid?
You should be good. Typically very little fluid comes out.
I have had more transmissions out than I can count and the rust on the drive shaft is concerning me. If you have that much water in the transmission it will not last long. Water is bad antifreeze is catastrophic. Antifreeze attacks the glue holding the linings to the steels and it will flake off. Its usual source is a defective cooler in the radiator. Other water ingress is typically from driving in deep water. I would immediately change out the fluid.
You will have to change it in the pan and then unhook the cooler line and pump out the torque converter.
