Q. If the car or truck concerns a end (in the course of the slow down/deceleration), I am able to hear a really noticeable humming seem. If i switch to neutral, this sound will disappear immediately. The sound is also apparent if the car is downhill with engine braking. Proton's https://gearboxcvtproton63950.blogsvila.com/34602858/gearbox-cvt-proton-options
