I was going to do steel braided, but decided not to.


What rubber lines are good? I used regular 3/8" heater hose but they always seem to break down and leak at the ends where the clamps are.

???

Buy fuel and oil rated rubber hose from the parts store, they will know what it is...

Why not the cloth braided line?

Thats what I should have put on I guess....lol

The PepBoys and Advance Auto here only have heater hoses......unless the sales people have no idea they sell that kind of hose.....

I saw some steel braided lines in lengths of 3 feet.........pretty expensive for 3 feet and I need one piece thats a little longer than that.

Where I buy the tranny cooler hose comes in clear plastic box hanging on the pegboard. The parts store guys often have no idea what they carry our on the floor. They probably .Dont carry it as cut to length, doubt you can buy longer than 3' easily.

Rubber hose needs to be NHRA approved if over a short distance, so if you are doing the whole length in rubber, you need pushlok style stuff.

Summit carries a ton of it, check it out. 6an and make sure you get the right fittings and don't buy worm clamps on it.

Running high pressure hot oil through long sections of rubber hose near headers would make me very nervous. How high is the pressure? Is it line pressure at nearly 200 psi?
One touch to the headers and you will be needed a new transmission.
Using Teflon AN hose and connectors makes the lines flexible and easy to remove/install.
Since my trans cooler has fittings for AN connectors, I don't have rubber anywhere.
Just my opinion.

My tranny lines start out in front of the engine coming off the factory metal tranny cooler lines....so they are nowhere near anything thats even warm to the touch. The hose that I need will run from there, and attach to the cooler thats mounted in front of my condensor.

The lines won't even get near the radiator.

How can I make these teflon lines attach to the cooler I have, which just uses worm clamps?

If you need any steel braid or Teflon lines and fittings, I have over $75,000 in stock of XRP fittings and hose.

I'll take $10,000 worth....lol


I'll have to measure the lengths I need. Whats the price for (Steel Braided) two 4' lengths and four fittings to weld to my two cooler ports and to the ends of my factory tranny cooler lines ?

The two lines need to run from where the factory tranny cooler lines end out in front of the engine.....to the cooler you see in my pictures in my above post. I think two 4 foot lines will be fine.

I have a basic B&M cooler......

How about this if 3 feet will work.....?

But what fittings go on the ends????

yes, that stuff works... the rubber hose is lined internally with a steel like material
its an AN hose, so just get matching AN hose ends...you just need to know what fittings are on your transmission and on your trans cooler...
the coolers have a 6an, and teh typical fittings for the trans is usually 6an as well..

its also a lot easier to get the AN hose ends onto it than using braided steel lines...
I used that stuff for my fuel lines on my camaro

You will need to use the AN fittings with that hose from Jegs. You can not use the barbed fittings and a clamp with that, it isn't flexible enough to pull over the barb.

Using short links where you are the cheap way would be to get rubber hose for transmission oil cooling, I bought some the other day at Advanced, 5/16" for $1.99 a foot, they had a big spool they cut a few feet off for me. It specifically says for "transmission oil cooler" on the hose I bought. I was using this on a car I was doing for someone else, because most people won't pay the price of braided stainless lines, and the correct AN fittings. Doing it the way I did with barbed hose fittings it was about $25, it would have been $100+ using stainless braid -6 hose and fittings.

If you go stainless ot that other hose from Jegs, you should probably run right from the transmission to the cooler in one piece, and get rid of the factory lines. You need 1/4" pipe thread to -6 male adapters on the tranny(you'll need 2), put fermale -6 ends on each of the hoses(you'll need 4), and then you need adapters to fit your tranny cooler's input(you'll need 2 of these). This is definatly the harder more costly route to go, but it probably the way I would do it if I did it on my car.

ScottBG's comments are good.
However, the "1/4" pipe thread " is not quite right. A pipe thread (which is tapered) will often work, but can also crack the case. Technically it is a straight thread with o-rings. AN6 adapters are available. Also it appears the oil cooler threads changed somewhere around 2008. My 2010 trans is neither 1/4" pipe nor straight; but an AN-6 male to make with an o-ring fits perfectly.
