Hello,
Typically a radiator will have cooler lines for the transmission. So you can see transmission fluid leaking out of a radiator but not engine oil.

If you have oil in coolant, that is a sign of a blown head gasket.
Check your oil to see what color it is. If it is milky white they you have coolant mixed in the engine oil.
There is a test you can do to see if you have a blown head gasket. That test checks for combustion gases in the coolant. When a head gasket is blown you will have combustion gas leak into the coolant from the engine.
Here is a helpful video:

Please let me know of any questions.
Thank you.
