I have a 2011 Ram 2500 4 X 4, automatic, diesel that has a vibration when started cold, usually below 40 degrees F. The vibration occurs usually between 900 and 1100 rpm and seems to go away once the engine warms up a bit. It is really annoying and sounds like it is coming from the center console or up under the dash towards the hood.

Has anyone else experienced this or does any one have any ideas on what would cause this? Thanks in advance.

 

Sorry for the late response. Let me move this to the Cummins section.
