Found oil in coolant expansion tank. What might be causing this problem?

Hi there, as your model should have a separate trans cooler, it must be engine oil. If this is just started you may have a head problem starting, flush the coolant and check for any coolant in the oil, and at this stage just see if it continues, if so, the head will have to come off.
