What do you use for transmission lines? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Trying to figure out what to use for my trans lines. Are you guys using rubber or metal, and how/where did you run it? Pics would be good.

I used braided stainless steel hose. I'm running a 4L60E. I had to get some adapters. IIRC the tranny has pipe threads, and I used AN fittings to run up to my aftermarket cooler.

5/16's metal hardline. and a small peice of rubber near the cooler to allow for engine movement. NHRA rules are no more than a foot of rubber hose so use less than that on each line. Use a bender, harbor freight has a cheap but pretty good one and it will come out looking nice and solid.

rubber trans cooler line all the way from cooler to tranny

all metal from trans to radiator, ran just like factory up the inner frame.

Ran hard line from trans between motor mount brace & crossmember & ended that after fuel pump. Then bent hard lines similar to factory out & down radiator with sharper bend at bottom to meet up with the other section. Used couplers to put lines together in the space between radiator & motor - easy access from underside. This allowed the rear section minimal bends after the ~45deg to get around the rear of motor. Also made sharper 90deg at radiator & down low easier. Truck was totally assembled & on the ground so the joint made it all easier to manage.

I just wanted to avoid any rubber cuz it seems like even the black tranny line stuff gets pretty soft after a few years.

Same here. Avoid any rubber lines with the trans cooler if at all possible. Just one more place for a failure that will leave you stranded road side when the rubber hose gets old and cracks. You never know when that is going to happen.

My Camaro did that to me on the trip home from buying it. Left me stranded 20 miles from anywhere in the middle of the Mojave Desert.
