Where can I get o ring replacements for the transmission cooling lines the ones that go to the radiator. I purchased a box at AutoZone with many standard sizes but they are too thick. It seems the old o ring is kind of flat on the OD. Any body know anything about it or do I have to replace the whole radiator which will probably come with the o rings?

Good morning,

Here is a guide to help you step by step with instructions in the diagrams below to show you how on your car.

Go to a GM dealer parts department and they will give you the correct O rings. You cannot use the universal ones as they will fail when installing. Is this the seal you are referring to? I attached a picture for you. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
