So after 3.5 weeks without my Porsche I finally got it back. My transmission was indeed failed at 22K miles. It had lost 1st and second. After the cost analysis was made, Porsche decided to replace it with a new one. Result? Car is better than ever and the shifts are now smooth and precise as should be. I still have a fear of engaging second and hearing grinding sounds. Overall this was not a fun experience but it was worth it. The car is much better now. The total bill? $5,850... My, am I happy I bought a CPO car... I faxed Porsche NA my rental car bill and hope they will reimburse me as the dealer did not provide a loaner.
