Hey guys, as you can see in the video, there's a loud vibration noise coming from the crank pulley area. The noise is there when the car is at a stop and the gear is in D or R. The noise tends to disappear and reapper sometimes when the gear is in N. I asked a mechanic, he said my torque converter is bad?! I've had the UR pulleys installed for around 12k miles. The car is 5AT as u may have guessed, and its NA. Thanks for the help.

EDIT: The pulley is torqued down to specs.
