What else could be causing the problem described below?
My car is leaking oil into coolant, making a burning smell, white smoke from the tailpipe, misfiring. Test for a blow head gasket shows that it's not blown. What else could be causing all of that?

A cracked head between the oil and coolant passages inside the head if it's engine oil, also quite possibly the automatic transmission oil cooler in the radiator if it's AT fluid. The head gas test only checks for exhaust gas getting into the cooling system, there's no way to test for a bad head gasket oil into the cooling passage of the head gasket leaks. From the sound of your description, the head is cracked and blowing oil and coolant out of the head cracked exhaust port into the exhaust system.

A cracked block or head. A bad intake manifold gasket. A bad radiator.
Remove the valve cover and pressure test the cooling system to check for a leak in the head.

is the car an automatic transmission ?? IF so, COULD a transmission fluid cooler built-in to the radiator that is leaking tranny fluid into the coolant ................

It would be helpful to know what engine we are talking about, but if your's happens to be one with water passages in the intake manifold you could have a bad intake gasket. Many GM engines from the 90's and early 2000's had this problem.
