Trans cooler line trouble

No argument that steel lines are better and preferred. I have installed transmission coolers on my automatic vehicles for years & there is no choice on the rubber hose there. Sometimes I have taken them off the old vehicle and put them on the new one. Never had any issues but those caused by my own incompetence. That was my point.

I know that I get tired on big projects sometimes & just want to get it done. Nothing wrong with a shortcut if it is done right. Sometimes you just need to choose what you spend your time and money on.
