This looks like a pita, I started the removal process, the cats are already out, but there is no space by the frame to get it out, already disconnected it from both sides, I only need to change the one on driver side.

I would remove the rear transmission mount and lower the rear to help you gain access to the line, this should give you more room. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

No, the mount won't do anything, the problem is getting the line from under the engine, it's already out of the transmission.

Thanks for the video. Yep, that is not a lot of room to remove the line, you are on the right track by raising the engine up to gain access to the cooler line removal. Let me know how it goes.

After twisting and tilting the line with the mount out it finally came out. God help me with the installation, I wish there was a way for me to just bend it straight and install it from underneath the frame.

Went in much easier than removing. Thank God the treads on the transmission case were not damaged. Hopefully there won't be any leaks. Removing the engine mount was the way to go.
