Unexplainable Transmission Stutter... help?

For the fluid to foam, the level has to be high enough to reach past the bottom of the spinning drums and sun gear shell. I think his intake gasket is loaded with vacuum leaks and his carb has dirt in it. Transmissions go out. With all the slipping going on, if it wasn't trashed before, then it is now. Probably from running low on fluid. I hear so often about how people are so afraid of overfilling their trans that they burn it up from running low; a lot more often than from overfilling.
