Default Oil in radiator is this a blown head?

Have a 5.2 v8 1993 grand Cherokee Laredo and just found oil in the radiator. Is this a blown head? It's not using oil, not smoking no moisture in valve covers. Everything seems to be running fine. No water on oil dipstick. Any ideas?

It could be the trans cooler.

If it does turn out to be a leaking trans cooler you will be needing a transmission soon.

I would go with trans cooler as well. that is the only thing I can think of that might have more pressure than the cooling system and therefore would permit the oil to flow out and into the radiator.

Yes, check the trans dipstick for coolant. To be sure, you can pull the trans pan and see if there's any coolant in it. Once you shut off the engine, residual pressure in the radiator will allow coolant to flow back into the transmission.
