That sounds like the fluid coupling or driveshaft center bearing and not the tranny. Drop the driveshaft so it's FWD and see if the noise quits.
Hey there Vstar - It took me some time (and about 400 miles) to get to it but I checked the driveline and carrier bearing and everything was solid. There is a small leak at the transfer case but the fluid was fine.
It turned that the
alternator coupler/clutch had seized. Apparently when this happens it causes the idler pulley to jump up and down and bang around. The idler pulley is physically low enough in the vehicle anatomy that it sounded to me like it was coming from the driveline.
Coupler, idler and serpentine belt replaced and noise is totally gone.
Have you ever seen this?
