So the noise described in that post could just be a failing center carrier bearing. It could also be a failing “velocity joint” or CV connecting the diff most commonly called. Neither are transmission related and are super cheap and doable by yourself. Have you looked at any of these yourself? The center bearing rubber usually cracks and starts disappearing and commonly makes noise switching between forward and reverse and can make a cowbell noise or grinding. You should jack up the car and look at the driveshaft for any rubbing which would be obvious as the driveshaft is flat black. See if there is an abundance of play with car off, in gear, in the air and parking brake set our DCT’s are pretty dang robust and rarely fail when not hammered on and sometimes even when being hammered on.
