Where is the transmission fluid located on a 2002 VW Jetta?

That's easy the 02 Jetta has a sealed transmission. You can not check it. YOu have to go to your dealer and have them look at it. They are the only ones that can. I work on alot of these as well as many other cars. If this does not help go to an oil change shop and ask them they will explain it better. Hope this helps
