The dealer originally only expected to check your trans at 80k. PTL they realized this was a mistake and called for a 40k fluid and filter change. So heres my advice. When you are down there to change the oil inspect the trans EVERYWHERE. Every bolt, seam, plug, and fitting, look for any signs of a possible leak. Make sure your hands are clean and even feel up around the top. If there are no leaks and the trans is performing well, then do not worry. Be prepared for your first fluid and filter change at 40k. I will document my first change using VAS6262 and Vag-Com. I ordered the filter and will consider a premature change at 20k. One for the experience and two to see if there is actually anything in the filter. I will put used and new fluid side by side for comparison. My guess is 40k fluid and filter changes are very conservative for all but the hardest of drivers and conditions, racers included. I think that the first change will be critical. I also feel that as the trans ages the changes will become less important. Castings clean up in time and any small particles that were left in from assembly are long gone. If nothing breaks in the trans the clutches will eventually wear and the trans is definitely worth a rebuild. Best trans I have ever owned.
