We have oil leaking into our coolant. Found it in the overflow tank. However, the Vue is not overheating and not using that much oil.

Are you sure it is motor oil and not trans fluid?

I am unsure. How would the transmission fluid bleed into the coolant?

The cooler for the transmission runs through the radiator. I have seen them go bad internally. As a result, ATF mixes into the cooling system via the radiator. If it is motor oil, then I have a concern regarding the head gasket.
