I have a 2011 Legacy 2.5 with cvt. 104k miles. Ours has a clunk noise. So of you accelerate and left off the gas a few 2nd later you hear a clunk. Happens everytime. Also if you are on the brakes and shift from drive to reverse after a second or two you hear the same clunk. Is this the start of the converter problem? It hasn't started stalling at all yet.
