Tranny lines?
 

I have installed a 4L80e into my Squarebody pickup and i had also installed the factory style 4L80e hard lines running up to the radiator. Now i am going to installed the AC compressor (now a LS based engine) and the hard lines are right in the way of the low mount AC bracket (which is exactly where i want the AC compressor to stay). I have tried bending the hard tranny lines out of the way but they continue to rub against things and I don’t trust them, long term.

I have ZERO interest in moving the AC compressor.

So my ? To you, whats the suggested soft line to run for tranny lines? PTFE? Or is there a strong version of a rubber type line I can run for my tranny lines?

Simple solution is to make some brackets to hold the lines out of the way where you want them. Strap iron is cheap.

Maybe something like these straps?

I've seen just plain ol oil/gas resistant 3/8" rubber (gas line ) used forever
If your worried about it not holding up you could upgrade to the 3/8" rubber fuel Inj hose..
Or whatever size your tubes are..

On my LS swaps I just use the typical rubber lined -6 SS braided lines. My 98 Wrangler with a LS6/4L60E combo has 15 years on it using it with zero issues.
I use Russell hose and hose ends.

I will look into that!

Thanks!

Use whatever folks use to add an auxiliary trans cooler. I used some to connect a cooler/condenser to the output of my air compressor pump. It is labeled on the hose "Transmission Cooler Hose". Or places like Jegs/Summit may have assembled sets ready to go.
