 At about 10,000 miles auto-transmission started making funny clunk sound and at 25,000 miles transmission started slipping even more. VW dealer said "it's normal" and mechanic said: "they all do loose their transmission". This is my leased vehicle. In the mean time I bought Golf Rabbit 2.5 (4 doors) and its transmission died on me next day I registered it. While test driving it, I am thinking: this is normal clunk. Both transmissions are NOT serviceable (there is no hole to add oil or check the transmission fluid level). I traded-in "Rabbit" for Mitsubishi Outlander Sport. I am going to terminate Jetta's lease soon. No more VWs or any other Euro brands (last mistake was SAAB).  Yes, they look cute but reliability is zero. Services are expensive: oil change is $86 + tax. If you don't change oil at VW dealer, they will void your Warranty, they said.
