Sounds like you need a new radiator. The transmission runs fluid thru the radiator to cool it, but it should never mix with the radiator fluid.
Two things. Replace the radiator, and then service the transmission back to normal. Be sure to flush your radiator system very well. Transmission fluid will destroy rubber seals and hoses in the radiator system. If you flush it well, and service properly, it should not have done any damage.
