I replaced a 12" section of my tranny line with trans hose, and double clamped both ends. Are these lines under any great deal of pressure, and is this an acceptable fix??

i don't understand double clamping, if the first clamp fails what good is the second clamp??

It's been done before, but remember, transmission fluid is flammable. If the hose ruptures and sprays on a hot exhaust pipe or manifold, kiss your car good-bye. There's a company called In-line Tubing that makes original replacement lines. Their ad is in Super Chevy and Chevy High Performance magazines.

You should not have any problems as there is very little pressure in the trans cooler lines , By double clamping you increased the sealing area which was a very good idea ,, and Ken if one clamp fails well then the other clamp is there to back it up ,, the wider sealing area is the main reason as a 3/8 hose clamp isn't very wide at all so 2 clamps is better ,, steel braded hose would be better and it would be a good idea not to have this hose close to headers

I wouldn't recommend this for a long term fix, but I don't always follow my own advice. I put about 60,000 miles on a Camaro I had with rubber fuel line hose all the way from the radiator to the trans, both lines. I'm not particularly proud of it, but it never gave me any problems, so I never got around to changing it. Double clamps are a cheap and easy way to improve a cheap and easy fix.

If you buy a trans cooler it comes with rubber hose...FRED

Inline Tube 1-800-385-9452..Bought new trans lines from them for the Malibu, costs under $50 last summer. They have a web site:

IMHO: The double clamp theory is cool, the long hose, eh, not so cool. I had a 70 El Camino that had a spliced up trans line and one cold winter morning while backing out of the driveway, it blew off..now there's an eye opener. Just for the record: I bought the car that way.

What I've always done is get a flanging tool and flange both sides. The flange really keeps the rubber trans line on.

Very good point Ron http://www.chevelles.com/forum/smile.gif

http://www.chevelles.com/forum/eek.gif Just one very Important thing, Make sure you are use the type of rubber hose which WILL with-stand Auto Trans. Fluid! Some hoses will degrade fail in a very short time! I learned this the hard way a few years back.

I think it runs at 6 or 8psi not much, doubble clamp is fine if you want to get crazy with braided use teflon bradied.
