You need a new radiator if you have trans fluid in the radiator. Getting trans fluid in the radiator isn't such a big deal...just change the radiator.....the worrisome parts is getting coolant in the transmission. The radiator has a transmission cooler built in and it is separated with a wall of aluminum - the coolant and trans sides should never mix. First! You need to drain and remove the radiator and replace it with new fluid. If you got trans fluid in the radiator, it very likely means you got the inverse....coolant in the transmission. You also need to flush and drain the transmission. Also, you need to flush the transmission cooler lines out for any coolant. Coolant in the trans is often the death of a transmission. Make sure you use the right fluid in the trans. That vehicle takes Mercon V fluid - don't put anything else in there or you will have problems potentially.
I recommend every 75,000 miles.
