----2000 RPM's Moaning and even on compression at

----this RPM still Moaning but not as loud. I am

-There is a TSB that covers the moaning noise @
1600-
-2000 rpm. Do not recall the number, but my truck is
-scheduled to be fixed soon. Requires replacement of
-one or two motor/trans mounts, retorquing of the
-transmission crossmember, and loosening/retighting
-of the exhaust system.
