Was there evidence of metal in the transmission oil when it was drained, or only friction material?
Since the noise occurs at 2000 engine RPM with the vehicle moving it could be a few things in the transmission or it could be the engine or the accessories like the alternator, PS pump or water pump. Just to be certain the noise is not due to an external accessory it may be helpful to remove the accessory belt and start the engine to test it again.
About the only thing moving in the trans when in Park is the torque converter, pump, and drive chain and sprockets. If the fluid is not foaming the pump may not be the issue. There was a TSB (0-07-30-007A) regarding the chain, sprockets, and sprocket support bearings on the transmission, and that may be the cause. There is no good repair for this issue short of removal and replacement of the chain and sprockets. Transmission oil additives will not improve this. If the trans is removed for repair it would only make sense that new clutches and steels would be installed (complete rebuild). A used transmission is likely to have similar symptoms unless it is rebuilt to replace worn parts.
