Hi I have a vibration i need help diagnosing. First- I notice if I am stopped in either park, drive or reverse and not moving I get a slight vibration, but it goes away In neutral stopped. The major vibration is when the engine is revved at about 1800 -2000 rpms, and it doesnt matter if I am in drive or park, stopped or moving, before and after that rpm range it doesnt have the vibration. Any help or ideas?
