Ok, so you have a 10-year old Tiptronic tranny that you said just had a "good tranny" maintenance, but still shifts poorly. I would assume this was done at a reputable Porsche or German car care center? I am confused at how the tranny shop missed your obvious transmission failure problem. I fear that due to my extensive racing experience with other makes and trannys, you may be in for a costly repair or replacement. I have yet to see alot of "cheap" fixes to major shifting/tranny issues. Then you said you have an engine vibration? I would have to say exhaust, motor mounts, drive train etc....have you had this checked out by a Porsche technician?
all the best...
