WTB Tranny Cooler line #10269709

Does anyone have a source where to get AC Delco part #10269709? it's one of the tranny cooler lines and can't seem to find it online. RockAuto doesn't have it, Hamilton Chevy has them on the eBay store, but at $130, that's a little steep especially when the other line is only $14. thanks

Bend one yourself from a straight piece of 3/8" brake line.
The flares and inverted flare nut are standard!

What exactly is bad on the existing Line/Hose? Cause if you want to fix on the cheap, you have some options there. For example I just used Brass Plumbing Compression fittings on there when the Crimp portion was leaking. Some members have just used some worm Gears clamps in place of the Crimps. If the metal portion has a hole in it you could cut out the bad section and splice in 1 of these Brass compression fittings as well.

If you want to do it right, then replace the entire line. As you know OEM is pricey and you could redo that line in AN hose and fittings and never have to worry about it again. At $130 for OEM, you could most likely replace in a AN option for less than that. If you need more info on any of this let me know OR if staying stock...its a no-brainer.

My line is rusted pretty much all the way to where it meets the rubber boot. It is so like GM to continue to make one of the tranny cooler lines, but not the other one any longer. I might try the route that Nab has suggested. I've seen your threads before on the braided lines, and I actually bought those parts to replace exactly as you have, but since my line is rusty I'd prefer to have a newer one to use.

After looking at the pic of the line you need,
it would definitely be easy to make with what looks like a 30" piece.
The inverted flare nut will even screw into the trans cooler.
On the other end you could use a union and join it to a hose barb fitting.

Like Nab suggested, just make up a new section of Steel Line with a few bends. Then if on the Cheap, just use one of these Compression Fittings....

https://www.amazon.com/Anderson-Meta.../dp/B000BO9DYO

....which you can pick up at home depot or Lowes. On the other end, just replace the Nut and Ferrule with a Brass Hose Barb that threads on "in place" of the Compression nut. Just be sure to use hose that is compatible with oil/fuel and you should have a repair that will hold up real well. My Comprssion fittings were on there years before replacing with the AN setup.

EDIT - Something like this on the other side of the compression fitting linked above.

https://www.mscdirect.com/browse/tnp...CABEgIMVvD_BwE

Just open up the box at the store, remove one of the Nuts and make sure the Female Hose barb threads on. For about $10 - $15 in fittings and a few clamps (per side), you got a ShadeTree repair that will hold up very well. Nice thing about the Compression Fitting is you dont need to "flare" the end, just use a Straight Cut on the Metal line with a tubing cutter....EzPz.

I'll have to disagree with 4door here.
A compression fitting is what you use if your stuck on the side of the road.
It's not a permanent fix.

I wouldn't rule out a compression fitting as a permanent fix - they're used all over the hydraulic industry at thousands of psi for millions of cycles without failure. They're simple, inexpensive, easy to install and work well - what's not to like?

I've put them on the high side of my A/C line as a repair almost 10 years ago with no issues and wouldn't think twice about putting them on a transmission cooler line or anywhere else. I have them on power steering lines as well in 2 different vehicles.

As long as they're properly installed (which goes for any kind of fitting), they're as good if not better in some ways than inverted/bubble flared fittings in my opinion.

Compression fittings are what you use when your stuck on the side of the road.
It may be common practice in the plumbing industry where water pressure remains
in the 40- 60 psi range.

Would you use a compression fitting as a permanent fix for a broken brake line?
