I have a tranny cooler with a fan and the lines. I used this maybe twice in my rig when I rebuilt the th400. Tranny was crap, went manual. Could prob use a good cleaning on the inside to get the burnt fluid out. I cut the last 6 inches or so off of the lines to see if I could route them in the new tow rig. Thing is just way too big. I can put the ends on the rest of the line for you as I also bought the tool. It also has the fittings to go from the tranny to AN fittings. I have over $250 into this setup. Looking to get $180.

might need that for my buggy. what's the actual size and thickness?

There was some specs in the summit link. The mounts add maybe an inch on each side of the cooler. Ok well the 2 sides. The line is areoquip socketless.
