Jeep trans problem

You could always pull the pan and check for shavings. You'd be out a few bucks for a new gasket/fluid and a couple of hours of time.

I'd also check your coolant level/color. Is it possible the radiator has started leaking coolant into the radiator lines? That could explain the bubbly transmission fluid, overheating, and high level.

Edit: Yeah....what SS said.
