My cherokee 2000 started leaking from the transmission cooler line, so I had to replace the whole line, the upper line I believe.

There was a little plastic thing and then a small washer/bushing nut thing that went into the end of the line that plugged into the transmission block. Apparently, it didn't plug in well enough on the block, so at some point while driving it came loose, spilling all my transmission fluid and then this little metal washer thing came off and was lost.

Now my poor jeep is sitting and unable to run until I can plug this line back in.
I need to get another one of these "bushing/washer/nut things" that go into the end of this line and into the block.

You know what it's called, so I can get one?
(all jeep dealer's stupid computer system is down, so apparently they're clueless without their precious computers)

Thanks for the help guys.
