Check the tranmission fluid level. I have seen where the transmisison cooler may develop a crack and bleed some fluid into the cooling system. Trans pressure operates at a greater level than the cooling system so there's probably not a risk of getting coolant in the transmission. Keep an eye on the fluid level. If it was engine oil, you would probably be having a driveability problem by now.

the motor oil was about two quarts low and it never used any oil before.

How much oil is in the radiator? Typically if there is a problem, the oil shows up in the overflow jug. If the transcooler had a leak, it would show up as strawberry milkshake, snotty stuff in the coolant, very unattractive stuff. Either case would be a rare occurance for this model.

Sounds like a possible blown head gasket. Time to get a compression and leak down test.
