Ok I had bad trans cool lines. Couldn't find the correct line after market so to it in the arse bought them from the dealer for 300+ American dollars. I re used the old plastic quick connects. Which were ok for awhile. The other day headed to work I blew that line off and rust prodded the underside of my jeep. I tried many things to get around the quick connects. I made my own rubber line with nice ends. Now I have no leak at the line connectsim having blow back through the pan. Wtf !!! My brain is rattled and I need help form all the jeepsters out there. What do I do now.

Which is the pressure line, is it the front or back line. I've been messing with them so much I'm not sure now. Up front I know the one that goes into radiator is return line and pressure goes into cooler.

on the trans the line closest to the motor is the pressure line, it also has a threaded connector. the pressure line goes to the radiator, then to the aux cooler, and then back to the trans at the rear closest to the transfer case. that connection in the rear is just a quick connect with a plastic clip. I just redid my entire trans line setup when i did a full drivetrain swap, I picked up all 4 of the lines from napa for $105. trans to rad, rad to aux cooler, aux cooler to return line, return line to trans.

You can get a different tranny-side fittings from WJ, they are regular flare-and-cone with a flare nut.
You'd have to flare out your line ends though, and if they're steel it's not going to be an easy job.
Steel tends to split at the flared end.
Or hack off WJ tranny line ends and use rubber hose with clamps to your old tranny lines
