What I don't understand is how your mechanic determined that you have a trans problem and would have been ready to order parts if he could get them!!!
Did he tell you what parts he thought were defective and needed to be replaced???
Just buying mine back in April, I probably have the same or similar noise that you have....when you depress the clutch pedal, noise goes away, of course when you let the clutch pedal out and put the vehicle in motion, the noise is present. I thought it sounded like the throw-out bearing, and another member also mentioned that it could be the pilot bearing making this noise (or sound).
Either or, apparently it is no biggie, I have no problems driving with mine with that noise, in fact I just block it out, and don't even notice or pay attention to it anymore.
Why did you have it towed????
Does it not move under its own power???
Is there any problem putting the vehicle in motion and shifting the trans???
You mentioned that you drove it 3 miles 2 years ago and parked it, don't you think that some "things" might have dried up a little over that time, and need more movement to get everything properly lubricated once again???
If someone drove you 3 miles and parked you for 2 years without any movement, what do you think would happen to you???
I think you should drive your Z, unless it won't move under its own power and is making such a noise that in fact it would indicate that something is broken...JMO

What you said about the mechanic is exactly why I'm on hear asking and not even sure it's a transmission issue. He gave me no specific diagnosis or parts needed, and as I said he didn't take the trans apart, so basically it was just a guess on his part.

I do understand that without driving it for nearly 2 years things will dry up and need to be relubricated and frankly can go bad from not being driven. I drove it far enough that if that was all that was needed the noise would have atleast let up some, thus I drove it in to have it looked at.

I chose to have it towed because upon first hearing this supposed diagnosis from a very reputable corvette mechanic my first instinct was that I didn't want to add miles and possibly damage the car. But now that I've gotten it home and had some time to think it over, I'm more and more unsure the transmission is the issue.

I'm hoping it's a much less expensive issue and an easier fix than a transmission issue, and maybe it is a transmission issue where the car was serviced and the fluid was drained and replaced with the incorrect fluid. I haven't had a chance to investigate myself and was hoping to find someone with some insight or who has maybe had the same experience. I'll definitely look into the issues you mentioned, so thanks for mentioning them.
