Hi, I changed my tranny fluid on my Boxster and used lubro moly 75w90 gear oil. So far no issues. Very smooth shifting. That being said I trust what JFP is saying, the only issue is that the Porsche fluid is difficult to get. The reason I went with Lubro Moly is because a Porsche Indy Shop said they used in all the Porsches they service. Will keep you posted if I have any ill effect going forward but so far so good.
