which is it? you've seen it or you've heard of it... come on now. you're changing your story to make you look better. we're all a bunch of nice guys, but that is NOT gonna fly here.

I say it with pictures
The only aluminum ones I've ever seen were replacement ones from Autozone. The replacements I got for my Lumina from O'Reallys were not however. They were just like the originals.
BTW... I have the same clunk on my Grand Prix, so when you find it for sure and get it cured, please post up.

perhaps you already have done like i suggested to the OP, it's an easy thing to check, but take a peek and make sure the dog bone mounts (at head) are tight.

Oops, actually I had that backwards..... I got mine from Autozone and they were the same as original. The ones O'Reallys had were the aluminum ones.

Toasty....I do believe what 19SE92 was saying is that he has seen them break, however as for the reason they broke, he heard it may have been metal fatigue.
Lets not be so quick to jump to judgment guys and gals. Lets try to keep to the facts and not throw a bunch of emotion into it. Please leave all bigotry and drama at the login screen.

ok back to what the op asked... the same thing happens on my car and so I've been trying to find an answer. GM actually posted a bulletin about it, and I'll paraphrase.
When shifting between park and reverse, park and drive, or drive and reverse, a clunk noise is the result of a buildup of lash (freeplay) in the driveline. Owners may comment the clunk noise happens when the accelerator is quickly depressed and then released. In service dealers are discouraged from attempting to repair driveline clunk conditions for the following reasons:
1. comments of driveline clink are almost never the result of one individual component with excessive lash, but rather the result of the added affect of lash present in all the driveline components.
2. Because all of the components in the driveline have a certain amount of lash by design, changing driveline components may not result in a satisfactory lash reduction.
3. While some owners may find the clunk noise objectionable, this will not adversely affect durability or performance.
The sad part about the whole bulletin is it just simply says "poor engineering." Hope this answers your question though!
