UPDATE # the sound is still there also the sound is audible when car reaches its temperature (middle b/w cold and hot) when car is cold there is no sound and when car is in its temperature the sound can be heard what does this mean?
AOA. Ramazan mubarak to you all. We recently bought a Toyota Premio and i changed its cvt oil and did basic tuning like cleaning spark plugs throttle body cleaning and oxygen sensor but upon acceleration of car it produces "krrrrr" sound not in neutral but in D or S. Whenever the car is accelerating in 3-4 rpm it produces the sound and when the car is driven on low rpm it does not produce the sound. Also the sound is coming from the very bottom of the car not above. (i think from gearbox area). I checked the oil it is ok and also some otherthings they are also fine but the sound is still coming. the sound is not of knocking. will be looking for suggestions about the problem Regards. will upload the audio of sound as well tomorrow as the car is not with me now. the oil i used was silver tin Toyota original cvti oil 4L
