just got off the phone with the mechanic. he thinks it is definitely the dampener and there is no updated one. he said if it was his he would run it. just a matter of if you can put up with the rattling noise or not. he did find a small leak on a valve on the side of the transmission i had'nt noticed so he's going to fix that and put a third valve on the front and i'm going to run it atleast until i hear of an updated dampener.
