2008 Turbo Tiptronic Clunk and fluid question

I have a 2008 Porsche Turbo with Tiptronic. I took it into the dealer to investigate a soft "clunk" sound which sometimes happens when it downshifts into second gear. Car has 69000 miles on it. Now he tells me that the tranny has the wrong fluid in it. I know it's the original from the factory fluid as I've never changed it and I bought it new. Dealer says the fluid is white and should be red. Could this error of Porsche's have damaged the tranny and caused the "clunk" sound?

First don't trust the dealer, if they come up with something like that RUN get a second opinion from a trusted independent shop who is familiar with the modern Porsche. That transmission has two parts to it, the transmission and the differential. The differential fluid should be gold, and the transmission fluid should indeed be red. This thump is likely from the transmission mount. Have your trusted independent shop thoroughly check the transmission mount rubber for wear.
