tranny cooler lines

in regards to :
http://73-87.com/7387garage/drivetrain/tranny_hoses.htm

mike has almost the same tranny cooler as i do, but mine doesnt have the threaded in/out ports on it, just a nipple.

my problem is after a while, the rubber hoses that connect the cooler to the stock metal lines, they start to deteriorate and leak quite a bit.

i'm wanting to add actual fittings instead of hose clamps that it has to use.

whats the easiest way to fix this problem besides buying a new tranny cooler???

Re: tranny cooler lines

A long time ago I was working on this for my old 71 chevy. I plan on doing something similar on my 67 Burb.

Try finding a place that specializes in hydraulic fittings. I think if you bring in your tranny cooler they should be able to get you set up. I think you will have to use the type of fittings that use a metal ferril (sp?)...I think they are called compression fittings. I've used them at work for high pressure hydraulics and stuff.

It's been a while since I checked, but I think summit or jeg's has a tube to AN fitting adapter...just not sure if it is the right size. Hope this helps.

Re: tranny cooler lines

Are you using hose that is rated for ATF? If you use fuel line, the ATF will eat it up. Mine is put together with rubber hose rated for ATF and hose clamps, and I have never had any trouble. It was that way when I got it 5+ years ago, and I only replaced the hoses once when I had everything apart. The hose is available at auto parts stores, usually in the same section as the transmission coolers.

Sorry I didn't actually answer your question...

Re: tranny cooler lines

Oh, great... Just a note of things to come, since I just installed a B&M cooler with the slip on fittings. I will be looking forward to that one in the near future.

Re: tranny cooler lines

I have had a trans cooler with slip on fittings on my truck for quite some ($ years) time and have had no leaks. Definitely check the type of tubing that you are using.
