There is a black substance that looks and smells like motor oil in the coolant tank, although there is no water in my oil, and the oil does not appear low. Neither does the transmission fluid. Since the there is oil in the coolant, when the car is running the fluid travels to the radiator and causes it to smoke, and the car to run roughly.

It sounds like you have a bad headgasket. I would have that checked.
