The Tiguan and Jetta both have similar noise concerns with the same/similar Aisin tranny. Seriously, noise and problems are not one and the same is all I'm pointing out. While it may be irritating to get some t-converter noises from low-speed/low-rpm operation, I hate to say it..."it is what it is". There just isn't any sing that these trannies are having mechanical issues. I drive ours infrequently as it is my wife's and I hear it and just don't pay attention anymore. It's so infrequent (the conditions needed to replicate - near-stop/hangs in third/1000 rpm/accelerate). There is so much info I've found/posted relative to this I'm not going to do it here - some simple searching here, the Atlas sub-forum on vwvortex.com, and the Atlas/Atlas Enthusiasts Facebook pages should be your go-to.2 questions for you KarstGeo — 1) I am unaware of any other car that makes this noise – intentionally, and 2) If it is just a normal noise, why is it getting worse with time?
Some other VWs are showing the same symptom. A local VW mechanic says the Jetta is coming in with this issue as well.
