I do experience some rare engine vibration on my 2019 ExI when shifting on low rpm(2000). I am not sure if it is the VCM that causes the vibration. I read a lot about VCM and to be honest I am a bit confused. People on the thread seems not to like having a VCM and they have installed this so called VCM muzzler or disabling the VCM. My question is, how bad is the VCM? In what mileage will I see the effect in the transmission/engine?
