When changing out the radiator hoses on my wife Base 2008 I noticed a little oil residue on the lower transmission cooler line. It is leaking were the rubber and metal line fit. Been doing searching see it has quick disconnect lines. Is there a part number for the blue o-ring in the fitting? Was thinking instead of replacing the full fitting just replace the one O-ring since the fittings are not leaking. Also was trying to find a write up on how to change the lines just to know what I need to tear down to do the lines. All the DIY's I am finding is doing the external cooler and no longer doing the radiator version. Around me looks like Napa is the only one that carriers both lines. At least hey are not expensive so thinking of changing both while I am at it.
Found out my wife never had the fluid change and she is going on 93K. Not looking forward to dropping the pan for that mess. Miss not having a drain plug like on my Subi.
Thanks again for all your help. This forum has been great for me getting down this car and my Mom's old 07 Buick she just sold.
