Transmission Cooling Line Retaining Clips -- Which Brands & Part Numbers Work?

[Scrappycrow]

Y'all,

After a long day of wrenching, one of the last items to do was reconnect the transmission cooling lines to the radiator, but one of the retaining clips went "BING!" and shot off somewhere in the engine compartment. 45 minutes of looking in every nook and cranny, doing lots of "reacharounds," and shoving magnet retrievers everywhere, it's nowhere to be found.

I am having a heck of a time finding the part on GMPartsDirect, but Summit has:

- ACDelco 88960976

- Chevrolet Performance 24205103

- Dorman 800-801 (but a one-star review says "The 3/8" clips will not work with 3/8" line.")

Any suggestions? I need to get this taken care of ASAP, so it looks as if I'll be doing a 120-mile round trip to Summit tomorrow morning (it is not an enjoyable drive -- I'm 30 miles north of Atlanta and Summit is 30 miles south of Atlanta, so that's a lot of traffic at most times of the day).

Thanks,
Scrappycrow

I had the same thing happen, but fortunately my new radiator had new clips...

Looking at the AC Delco and Chevy Performance you listed, the Chevy Performance has Tahoe's listed under the applications, whereas the AC Delco shows Corvette and Impala..

Ah, I hadn't caught that, as I'd drilled down to the parts via the vehicle selection first. So, something in their process is out of whack. Now I see the ACDelco "applications" page has an entry "Application Notes" that says "OD 28.77MM EXPANDING SPRING WIRE BLUE," which means it's about 1-1/8" OD - way too big!

That does seem large, MAYBE for the engine oil cooler line (the OD of the fitting is ~1")
but definitely too large for our trans cooler..

@donjetman got it for ya... https://www.tahoeyukonforum.com/threads/trans-cooler-line.109972/post-1312942
Chevy Performance it is..

24205103 is the correct part.

Now, you can find this piece as part of the fitting that screws into the radiator and internal oil cooler at your local auto parts store, saving you a drive down to McDonough.

ACDelco 15226661

The stores carry Hayden, Murray, Dorman fittings with the clip included. They're probably on the HELP isle too.



Now you know why they tell us to use the Lisle 22930 Jiffy-Tite low profile disconnects. The clip stays put and doesn't get the chance to fly away.

the help isle of my local autozone is where I found a box of assorted sizes years ago. they have worked for me over the years.

replacing the whole fitting is nice if you can thou too.

Thanks, that clears up a lot and will save a good bit of effort!

I happened to already have the Lisle tool in my Summit "wish list" for the next time I do a mail order. They're not in stock in McDonough, so I wouldn't have been able to get it today.

@OR VietVet I was actually thinking of replacing that oil cooler housing on our 3.6. It's got like 91k and I haven't seen any leaks (yet). I looks like the Dorman upgraded all-metal is the way to go?

Anything else that should be done while the intake manifold is off? I've replaced the alternator, ECU and the heater core lines on that vehicle, but nothing else. I don't really like working on transverse mounted engine vehicles TBH, but of well.

I have a set of the Jiffy-Tite tools and they do work as advertised. I also have 4 of the thread in connectors, in case.

I have learned that if I gotta work with a small spring clip, it will fly to who knows where.
