OK, looking for input (what else is new) on trans cooling lines. I made mine up out of tubing 20 some years ago, well its time to replace them since while trying to re install one got bent in half.....maybe i was being too forceful.
whats the right product to use going back in , premade, re make out of tubing , or the braided. any input would be great

if your lines are fine otherwise, the right diameter, and good, you should have a section of hose in these lines as to protect the lines from becoming brittle (notice how the brake line has the loops, that springy design does that for those)

you just need a tubing cutter, a flare tool, and some trans cooler hose in the right diameter. 3/8 is a common line size, is that yours? Just cut to good metal tube, flare a simple flare to keep from shooting off push hose onone end, install,then install other end as necessary. then clamp(slide them on before the second line) preferably constant tension or fuel injection clamps, they can be bought for the hose size you get.

np. also driveline shifts, which means those lines probably "pivoted" on those bend points for some time.

If you use hose or braided AN line, make sure it is transmission line rated. The pressures and temperatures you can see on a hard worked transmission can do really bad stuff to fuel hose or regular braided AN line. Brained AN line is fine, just make sure it is PTFE, not the other cheaper stuff.

I would personally just cut out the bent section, flare both ends, and put standard rubber transmission cooler hose in to replace those sections. Use good quality clamps and move on. You can get transmission cooler hose at almost any parts store by the foot.

The factory cooler lines on my 2000 Ford Expedition had a section of rubber hose in the last foot of each line before it connected to the radiator, so they didn’t think all hard line was a good idea.

You could just do the quick and easy thing and order the correct made to fit lines that Summit racing sells. That's what my son did, easy install, no hacking, clamping, no blood.
