Transmission to radiator cooler fittings for aux cooler

[HornedToad]

Anyone know what the fitting interface is for the 03 04 (and earlier?) transmission cooler line to radiator? I can't seem to find anything on the size and I am beginning to assume it is one of a kind. Ideally I'd like to find an adaptor coupler that is this size to go into the radiator cooler and -6AN on the other side. Any help is appreciated.

Not quite. I am pretty certain that what I am looking for doesn't exist but I figured I would post up anyway.

I have some PTFE 6an hose (since the rubber lined 6an hose I installed two years ago with my Setrab cooler started cracking, crumbling, and leaking in three different places within a month) but it has almost no stretch and won't fit over the factory barbed fitting. At this point I think I am just going to take the fittings to my friend's shop and turn down the barbed section on the lathe to a diameter that will work. Shouldn't take much.
