I had a funny conversation with the service advisor at VW today. I went to get my oil changed...before any comments I don't do fluids usually. Well just did the clutch bleeding myself but thats different. Not worth saving 30 bucks to deal with the hastle and mess. Anyway asked what it would cost to do the tranny fluid. First dealer. Oh it's a sealed unit and there is no way to service it. Ok. Next. Called another dealer. This one told me the transmission doesn't have fluid except for the clutch fluid in it. Uhh what? I said the clutch shares the brake fluid and I just changed it. He got pissy and in a condescending your an idiot tone said "No the brake fluid is for brakes and the clutch fluid is for the clutch and that is the only fluid in the transmission." I said have a nice day. I will be nice and not give you his name and what dealer but my word Capistrano VW in San Juan Capistrano at least give your employees a book or something. Here's a good website
