Hi, I have been searching most of last 3 hours and can't find anything about the automatic transmission cooler lines, I just replaced them today. I did not replace the seals as they seemed very hard to get at to remove and replace them.
My trans cooler lines were leaking slightly the rubber hose to metal line connection on the upper line.
I did see that there was a recall or TSB on the line assembly but not the seals, and they do not come in the package for the line assembly.
My question is has anybody needed to change these seals, and if so how did you go about it?

2007 2.2 liter automatic transaxle.

We are talking about the fittings that the line plugs into? Number 8

From lucky's diagram, It doesn't look like there are any seals. At least on my 2008 #8 was molded into the radiator, My book showed it as removable.

The seal is inside fitting #8 if I remember correctly I have seen an aftermarket o-ring replacement. I have always just replaced the whole fitting #8. it threads into the radiator then the line snaps into the fitting.

I can't say that i have replaced these on an hhr but i have replaced them on many other GM vehicles.
GM has used this fitting for quite a few years across the board.

While doing some other things, I noticed a couple of liquid drops on the garage floor. I found that there is a little tranny fluid collecting right where the rubber part of that line bends. (Mine has a cover similar to split-loom on it).
As best as I can determine, mine is beginning to leak at the radiator.

Would I need to only replace the seals, or go ahead and replace seals/lines and everything?

Also, I am waaaaaaay overdue for a tranny service (never had one). So would it be better to let the stealership replace those parts, then flush/service the transmission all at once?

Thanks.

My Kwik-couplers at the rad are dry , I'm asking about the seals #4 in the diagram there are two one for each line. Thanks for the diagram Lucky this makes the description much easier

Your talking about these. I myself have not changed these out before but I think they press into the trans case like a trans filter seal

Well I have to answer my own question, I replaced the trans line kit last Saturday, have driven about 275 miles since then no leaks at the trans seals in question or at the rad Kwik-connects. now to get the transmission fluid level double checked and I'm good to go!

Anyone have part numbers/descriptions for parts 6, 7, 8? That is where mine is leaking.
