It's still under warranty right? Serious, take it back and
tell them to replace the dang throw out bearing. Whether they hear the sound or not makes no difference. They probably have a selective hearing problem on all the warrantied cars. As well as selective eye sight. If they won't do it check out your Lemon law for your state. Usually if you have had it in the shop at least 3 times and it still isn't fixed it's considered a Lemon and you can take it back to them and get a new car. I know it looks like you have the Limited Edt. 99 35th but getting a new 01 is better than fighting with the current car and will be worse once it's out of warranty. A letter from your lawyer usually wakes them up a bit, too.
