Default Buick Century transmission cooler line

I have a 2000 Buick Century that I need to replace the lower transmission cooler line. It is leaking right where it goes into the radiator. How do I disconnect and reconnect the line to the radiator and transmission? Is there a special tool that I need?

I had to look it up just to make sure, but this appears to be the tool used...

If you have the quick disconnects which the above tool is used for, I have always used a jewelers screwdriver to remove the spring clip and just pop the line out.

I think it has spring clips so I will try using a small screw driver to pop it out.
Is there some sort of pressure seal that goes in it as well? The leak is coming right out of the fitting. If there is not a pressure seal in there I don't know what would wear out that would make it leak there.
