1990 with 125k miles. I've got a leaking transmission cooling line (passengers side). The original line in metal. I can't find a replacement at rockauto, the Autozone only has a rubber line.

Any idea if I can replace with rubber or where to get a metal line from or some other form of fix?

 

Rubber, assuming it is rated to deal with ATF, should work. That said, you should be able to call around to some transmission shops who can custom bend metal tubing for you and put in a new set of metal lines.

 

Thanks Shipo. Got some rubber replacement hose and swapped it out. Good as new!
