you are going to need special pliers or little plastic tools that seperate the quick dissconnect fittings on the cooler and tranny sides of the lines. they look like little circles with a collar comming up through the middle. they are cheap and can be used over and over, mainly they are for fuel lines comming up to the fuel rail. I needed them when I did mine.
