Hi
My tranny cooler lines are getting wet. I called the dealer and made an appointment to have it fixed. The dealer said this is a common problem. Has anybody else had this issue with their HHR? I have 22,000 miles on my 2010.
Thanks

 

A few have, its more likely the seals going into the rad, take a closer look.

 

Mine turned out to be the seals at the rad end of the hoses

 

Thanks for your input on this
Would there be a part number of the O ring?
I could pop it apart and do the repair myself instead of going through the hassle of dealing with the dealer.

 

This may offer some insight.
AUTOMATIC TRANSMISSION OIL COOLER PIPES. Fits: Cobalt, G5, HHR, Malibu, Malibu BASE 4 DR NOTCHBACK, Malibu LS 4 DR NOTCHBACK, Pursuit | Nalley Buick GMC Brunswick

 

The release tool will cost less than $2.

Give the Commonly Used Part Numbers - Chevy HHR Network thread a look, it may be there already.

 

I used a small flat blade screw driver to gently release the horseshoe clips

 

Doesn't show detail for the top connection in that diagram, is it the same parts for top and bottom seals?

 

#8 is for upper and lower tube to rad trans cooler

 

Is #8 the fitting that holds the o-ring that can leak?
If it is, can the o-ring itself be changed?
A picture of that part itself would help.
I do have o-rings at work that are used for hydraulics and can match up the seal if need be.
