Most likely it's the water pump seal. When the coolant cools off, there's a vacuum effect that can draw trans oil into the cooling system.

I was thinking unburnt premix was the oil I was finding in the coolant as when I initially posted with this issue folks were indicating the head o ring.
So when the cooling system cools down it can pull tranny oil into the coolant....hmmm. The consistency of the substance I am finding in the coolant is more like tranny oil then premix.
So next question: replacing the water pump seal-anything special with the GG's. I have done a couple on other makes but never a GG.
I think I have a spare seal
