Grinding/chatter when coasting

Hi all new member here, I just bought a 2017 ram 2500 4x4 Laramie with the 68rfe with 32,000 miles completely stock, about a week ago it started making a grinding or chatter when coasting with the exhaust brake off around 900-1200 rpm... very slight vibration can be felt with it as well. It only does it while the truck is still in tq lockup, it chatters for a few second then quits then starts again then quits and so on until the tq unlocks... not very loud but aggravating. I was wondering if it could have something to do with a slight surging feeling when it’s in reverse which it only does sometimes... kinda has me nervous as it didn’t do any of this when I bought it and I’ve had it only a month. Thanks for any guidance
