Expert advice needed- Toyota vitz 2006 noise problm
AOA guyz, im facing a prblm and need ur advice.
Few days ago i bought toyota vitz 2006 model 2011 import (petrol) (85000km driven) and im facing a prblm, when i press the accelarator and car starts moving a kirrr kirrr sound start coming out from the engine or gear box, and when car gets accelarated it goes away and suddenly when the gear changes it again comes out and fades away and so on, so the summary is that when gear changes it starts coming and especially on low rpm when the car is on low speed and the accelarator is very little pressed and the engine gets load.
Kindly advice me is it due to the CVT transmission oil which i think locally relaced by the mechanic coz i hav the receipt from the previous owner, do i hav to replace it by toyota's genuine oil or anyothr suggestion? Thanks
