SOURCE: creamy sludge found in radiator.
Transmission fluid goes through the radiator to cool. The line could be leaking into the radiator as it goes through. Usually at the near the bottom is where the line goes in and comes out the other side.

There is oil in your coolant reservoir, you may have a big problem, either there is a crack between one of your oil passages in the head or the block and the coolant passage, your head gasket is compromised, or the problem could lie inside the radiator if the vehicle is equipped with an oil cooler.

take off the highest hose,blank one end and fix a hosepipe to the other,remove the cap on the top of the expansion tank and flush through(this way you will get no airlocks).flush for about 15mins,then reconnect,add anti freeze into the expansion tank,and run engine to hot.check for leaks,all done.
it doesnt matter if a small amount of oil is left in system.it helps if you can use the hot water tap for the hosepipe.ask permission from the wife first.....

Yes it is a blown head gasket. All of these symptoms are sure signs of a blown head gasket. The only other thing that it can possibly be is a cracked head or cylinder. But 99 times out of 100 it is just a blown head gasket.
