Hmm, well, that's a possibility.  In other words, it's not gear clash at all, but the cavitation of high pressure oil.  I'll mention it to the service manager.  Thanks for the tip.

I really miss working on cars myself.  However the Porsche requires a lot of specialized equipment, and manuals for a late model car are just impossible for the average Joe to get  --even if you are willing to pay the price (which I'm not).  Yet, when something goes wrong, I've just got to figure out what it is, even if it's not my problem.  It's like solving a puzzle.
