I have a 98 Buick lesabre and there is transmitted fluid in the coolant. I'm sure I will have to replace the radiator but what else will I have to do?

You are correct in assuming you will need to replace the radiator. Once you install the new radiator I would flush the engine out and also change the transmission fluid and filter in case coolant got into the transmission.

If you have not replaced the radiator hoses in the last coupe of years, I would install a new set with the new radiator.

And make sure the coolant lines are good. That's how it got in there in the first place

It is very important to check to see if any coolant got into the transmission. I mean like RIGHT A WAY. Coolant will ruin an automatic transmission real fast. The transmission fluid likely got in the radiator from a damaged transmission fluid line in the bottom of the radiator. It is possible that coolant got into the transmission also.
