Thanks Steelthee for getting back to me.
What really upset me was the jelly like rubber hose that was floating in the overflow bottle.
I do have a transmission leak, seeing about less than a teaspoon a day on the driveway. But no "strawberry milk" at all in the overflow bottle.
Can overheating cause the radiator fluid to become really greasy and turn the internal overflow hose to jelly?
I've included some photos of inside the radiator. Let me know what you think.
