I also wonder if the metal end is flared. Usually if someone is installing an aftermarket tranny cooler the kit will have some sort of flared line to splice into the existing hose.

If you look at this: https://www.google.com/search?q=flar...jGnHY6r2b7M%3A

you'll see that you could theoretically cut that whole junction thing out and just splice that thing in...
Just pulled the line apart. The black plastic is just a cover for the small c-clip thing. Disconnected it and pulled it out, a little oil dripped out. I ended up diggin in the rubber line metal connector and pulled out the small o-ring. Benz says they have o-rings in stock but the ones they have are black and this one is a light greenish color so I'm not sure if I want to risk trying that. I guess I could try and if it leaks then just cut the damn thing off finally.

Got an o-ring replacement from Benz ($4) and slid it into place inside the female connector, reconnected everything and drove around. Still a slight leak, UGH! Must be something with the actual hard line or the female connection on the inside??? I dunno but next step I guess is to just cut the damn thing off

It's fun and I don't really trust the dealer. Anyways I just cut the soft hose and removed the metal joint. Got some transmission oil cooler line from NAPA for $3 and a metal splice thing to join the new line to the old. Picked up some constant tension hose clamps and threw it all together and so far so good *crossing fingers* Oh btw, the two cooler lines are around $90 each from the dealer.
