CS3 Lancer shuddering problem

[~AlienCulture~]

Hey tuners, my cs3 lancer is shuddering when accelerating from stop, but when I cross about 20-30kmph, its ok.
It also shudders when braking as well.
It's an automatic transmission, CVT.

Any ideas?

check tranny mount

is it idling normal? TB clean? cvt fluid change history?
