Congratulations. The tip is easy to service just hard to find the filter/gasket "in stock". Be careful with the aftermarket suppliers on this as the tiptronic trans was used in some Audi's and I got a trans filter kit where the gasket was 100% correct but the filter was slightly different and the pan would not go back up correctly from Rock Auto or some place like that....
I think the Tiptronic Cab combination is the best of both worlds !
When buying Porsche Parts try Sonnen or Porsche of Delaware as they work on similar margins...nobody else even comes close IMHO
