Engine Cooling problem

There is transmission fluid in my radiator and overflow. The radiator has been replaced but the problem continues. What could it be and how do i fix it?

Trans fluid is sent to radiator (in an enclosed system) to cool it and return to trans.

Changing the radiator should have fixed it.

Drain and flush cooling system, there may have been some residual flud in radiator.
