Sound from gearbox

[flyturtle]

Hey guys I serviced my cvt gearbox at my trusted workshop outside and funny thing happen. First is the cvt oil that come out estimate less than 1litre. After that they replaced around 3 litre of cvt oil . After that funny sound come out when I started slow down after I drive in high speed. The sound I believe come from gearbox and I add the remaining cvt oil back to my cvt. the sound still persist . Any sifu can tell me what to do ?

For CVT, usually when it's over heat, it makes that sound.

RRRrrrrrrr like gearbox pulling high gear sound..

- Check if the CVT oil is the correct one
- If you drive highspeed a lot, recommended to add CVT Oil cooler.
- Recommend to flush the CVT oil and put in a new one again if the sound is consistent everytime you drive fast.

But you mentioned remove 1 liter then add 3 liters?
