Ok, I have searched and searched and have come up empty. Here is my story:

I broke down and took my car to an Indy for ball joints, new belts and to check out the motor mounts. I just wasn't finding the time to do this and now my garage is 100+ degrees every day

Indy said the motor mounts were fine. Other work was done and I was glad to be rid of the squeeking from the front end.

Next day I go out to start the car and notice a definite clunk from somewhere around the tranny area (best I can tell sitting inside). Noticed it on shutdown, too. Nothing unusual while driving, starting, stopping etc.

Took the car back to the Indy and asked them to check the mounts to see if someone loosened something and forgot to re-tighten. Sure enough, the right side was slightly loose. He also pointed out a 1/2" weld that has let loose on the driver's side, just inboard of the lower control arm bushing. He said that might be contributing. I will have the weld re-done, but it doesn't seem like I'd be getting a clunk in the center of the car when I do, from that busted weld.

Anyway, the tightening of the motor mount made no difference. I had to leave as I was late for a meeting. I really suspect the tranny mount and plan to take the car back at my first opportunity to have them check the tranny mount and do some welding. It seems like he would have checked the tranny mount, but after I heard the clunking and gave it some thought I realized he never mentioned looking at the tranny mount.

Any other ideas of possible causes that I might suggest the Indy look at?

Thanks guys - I appreciate your time!
