Default transmission cooler lines

Should I spend the money and order new metal transmission lines from ecklers for ~70 plus s/h or buy two couplers and run transmission hose?

I have an 80 vette, stripped threads on the TH350 so I had to cut the lines in order to get the transmission out. I am now installing a 200R4 but need new lines.

What do you suggest?

I've used short pieces of rubber hose on cooler lines with no trouble. I've also used hose for the entire length (tranny to radiator) with no trouble - this method allows routing to/from tranny to avoid high heat areas and give a clean, uncluttered look.

I prefer solid metal lines. Full length braided rubber/teflon lines would be my second choice. Short lengths of high pressure rubber hoses (made for transmission coolers) is my third choice. Full length high pressure rubber hoses would be my last choice. If you use rubber hose sections, the tubes the hoses slide onto should be barbed for holding power.

You want one end of the lines to be connected solidly to something. If there are flexible lines at both ends, the lines will be 'flapping in the breeze'. Since you had to cut the ends off, I would probably choose to buy new lines. But, the integrity of the system shouldn't be hampered if you use good compression fitting to put the solid line parts back together again. It's in an area where no one can really see it, anyway.

Thanks for the input. I am thinking I will fork out the money for metal lines.

If your lines are good other than the end stripped, you can go the parts store and get a short piece of 5/16 steel line, it will have the correct fitting on it, then splice it into your line using a compression union..

glarior,

I agree with 7T1vette and '75. There's nothing wrong with using compression fittings as long as they're fitted properly. I used them on my '74 where someone had cut the metal lines just in front of the crossmember with an oxy torch and fitted rubber hoses up to the radiator.

I fitted a cylindrical cooler mounted transversely to the crossmember and used compression fittings to make new steel lines from about the fuel pump area forward. The only rubber line is where the steel lines attach to the cooler, each is about 3" long.

Hope this helps.

Regards from Down Under

a good rubber hose should stand up to the pressures in the trans lines, if you decide to go the rubber route. But i'm definitely with the consensus... metal is the way to go.

I was going to put addition hose clamps on the hard lines themselves to keep the 2" hose sections from sliding. But.....how do you do this barbing thing? Thanks.

Using a barbed fitting at the radiator fittings or trans., using a tubing flare tool to create a bulb on the bare steel line. 2 clamps are better than one for sure but giving the hose something to bite on is better IMO. They also sell stubby fittings that will screw into trans./radiator fittings and have a few inches of steel tubing with a bulb on the end... I believe I've seen them at Advanced Auto. Here's one http://shop.advanceautoparts.com/web...%7CGRP2060____

This is the bulb end I prefer FWIW http://shop.advanceautoparts.com/web...roducts-_-feed
