03 Passat transmission problem

Hi all, :)

Was hoping anybody has a clue about some transmission issues. My ride has done 80K km recently have already done the timing belt and the waterpump.

I noticed that recently, the gear doesn't seems very responsive, it has to be pushed to over 3K rpm before it shifts gear. This happens from gear 1 to 4.

I understand from my friend in Shanghai, who owns a pasat 02, he too have the same problem. Can anybody advise? :eek7:

Thks
