WARNING
My trans line pulled off today... saw the leaking fluid when I got to work, popped the hood and fluid was everywhere. Luckily it was the clamp closer to the radiator so I could get to it by taking the intake off.
I never double-clamped... so I'm going to do that today. I may even throw some epoxy on the lines to help hold them in place.
Root cause? I don't think this is a daily driving issue. Today was the first time driving the Jeep since returning from offroading this weekend. My theory is those trans lines get taught during certain offroading situations like steep off camber climbs and the line slowly worked its way off. It may have been leaking on my drive home and I just didn't notice.... will have to check my driveway after work today.
Edit: also decided I'm going to pick up some 3/8" trans hose and make the lines a bit longer. .. maybe another inch or so. I cut mine to the same size that I took off, but maybe they get tension once in a while (hard acceleration?) and that's one of the reasons they're known to leak....
