yes are two possible problem. given the low millage i would rather stick to the cvt shudder. mayb if you give more detailed information others can help out. try posting this on ausjazz.org. thats the site delicate to jazz.

Either you bring it to mechanic to have your cvt flush (buy the cvt oil from dealer coz you cant use a normal one) or go to the dealer which should cost around 250-300.
