It's aggravating but the warranty covers the drive train, and they are finally fixing the problem. I got a surprise last year, when I took my "05 997 in for a minor issue (trim) and was told the Tiptronic tranny was among 260 that were in a service bulletin to replace. I had about 2500 miles on the car. It took a few days to get the tranny in, but months before they would shake loose the service bulletin. If you put the car up, you can tell the tranny is new, so no hiding it. I spoke to a guy locally who sells exotic cars, and he said this is the way Porsche does it, and having a major part of the drive train replaced does not impact resale. In fact, if there is a problem or a service bulletin issue which has not been addressed, he will not take the car for consignment.
