Hello guys! I'm having issues taking one of the cooling lines off of my transmission! I've gotten one off but the other I can't do, it keeps slipping on all the open end wrenches and can't seem to get it off! Any advice would be helpful! Thanks!

 

Go buy a line wrench

 

Wait lol, there's a specific tool for it? What are they called and how much are they ?

 

They are called line wrenches. You can buy them in a set or one just with the size you need. Your local auto parts place, NAPA, etc will have them.

This is what they look like. The first row or two are common examples.
