    This is my first time posting anywhere. But I have an issue with my 06 2500HD with NV4500 trans. I have a slight knocking like noise coming from the oil pan around 1800-2400 rpm. (Where it was the loudest) Ive changed my oil and I havent noticed anything in it. I was wondering if this could be a flywheel issue or what.. Im stumped and no one I know has not heard of this type of problem. Any ideas or suggestions??:confused:
