2011 Jetta S Transmission

Any help appreciated. This Jetta experiences high rpm's in shifts from 3-4, 4-5. and 5-6 when under light load going uphill, that does not increase speed but rpm's are raised as to indicate an upshift. VW says this is due to inadequate torque in engine and is problematic to all Jetta's. However, I am unable to locate such an issue in their forums.
