Whoops I broke a tranny cooler line, can I change to rubber hose?

[Great68]

The fitting to the rad was seized and when I turned the wrench the pipe bent and kinked and broke

I'm thinking of putting in an external tranny cooler, and changing all the lines to rubber hose. Is this easy to do on the transmission end? Is all I need to do is put in some new threaded to hose fittings on the tranny side?

Don't run hose all the way from the tranny. Cut the broken line and put a little flare on it to hold the hose and then get a screw in barbed fitting for the tranny at the auto parts store and use a short section of hose. It is still a little ghetto but if done properly it will look fine and function fine too.

I've used rubber hose before from the transmission to the radiator and as long as they're routed correctly and secured right, there should be no problem, The only problem here is the fittings that screw into the transmission case, I don't recall what thread they are but they're not easy to find.

D.hearne is correct, the ones that thread into the tranny itself are hard to find. I searched everywhere for a flared fitting like that, but nothing had the right thread, I wound up swapping the ones that are in the radiator into the tranny and installing barbs in the tranny. worked good for me.. I was told by some mechanics that rubber hose wouldnt withstand the heat/pressure of the tranny, and that you would need high pressure/temp lines.... Im running some braided lines right now and they seem to work fine.

Just ask for tranny cooler line. DOnt use fuel line.

IM using rubber tranny line and a external cooler, no problems at all.

you can get 25ft of steel braided line cheap on ebay. You cant use an AN style fitting on it. It is hard to find the fittings for the transmission, and hard to find the fittings for the radiator too...if you are going to use the radiator as a cooler. I have steel braided line from the trans to the radiator to the external cooler, back to the trans. It worked fine...when it was runnig.

I work at true value and i can say anything is possible. Go to your local hardware store and ask to see their flare and compression fittings. Im pretty sure the trannie lines are flare fittings, also ask to see some screw in barbs.

Hey all--

Quick question. Why not just purchase new hard lines in stainless from a parts house?

I'm interested in this thread as I discovered yesterday that one of my lines has a small crimp in it and I'll soon replace it.

What is the advantage over hard lines, besides ease of istallation?

Have a good one!

[Great68]

Thanks for the replies guys,

There's a lot for me to think about which way I want to do this now.

 

[allcarfan]

well, one benefit is, you can run the lines any which way you want. I have mine run under the front frame rail, through the fender well, under the battery tray, to the trans. Far Far away from the engine. Plus, steel braided line just looks cool....haha

 

[Great68]

I'd love to run steel braided, but it's just not in the budget right now

 

[allcarfan]

you can get 25ft of it for under $40

Allcar--what size do I need? What is all of this -6AN stuff? That's getting damn close to math for me. . . .

 

[MustangPaul]

Good News, possibly!

Are these the fittings that everyone is talking about? Mustangs Unlimited--$4.

Transmission Oil Cooler Fitting Set

Are these the things?

Those are the ones that screw into the cooler, not the transmission case.

 

[MustangPaul]

D--But didn't someone say that they took the fittings from their tranny cooler and put them into the tranny? I guess these might be for an aftermarket cooler--I haven't crawled under my car to see what they actually look like.

I guess that would be too easy!

[D.Hearne]

The fitttings for the cooler aren't hard to find, in fact you can get them at Lowes and probably Home Depot( or any other hardware store) The threads for the cooler side are ( I think ) 1/4 NPT. The flare side look like about -4AN. The Transmission fittings however are straight bolt thread ( not sure on what the proper term is here-- too early in the morning LOL) and need an "O" ring to seal , or as someone else said they're flare fittings ( may be both types used, depending on the transmission or year.

 

[LMan]

when you start fooling around with braided lines, you'll discover that the line is relatively cheap...its the fittings that will cost you!

 

[allcarfan]

you dont have to use fittings, you can use clamps or clamps that look like AN fittings.
