If you press harder on the throttle, do you feel it? If not, it could be related to transmission line pressure. For reverse to be achieved, the system needs to provide the highest level or line pressure that is used for any gear. Is the transmission fluid clean and full? As far as the torque converter is concerned, it could be related, but that isn't my first suspect.
Also, if it is related to a CV joint, chances are you would hear a clicking sound when turning the steering wheel all the way in one direction and moving. Take a look through this link. Look toward the bottom. It is the last paragraph before it indicates, "Got Any Questions." That explains the symptoms related to a bad joint.
Let me know if you have questions or if there is something I can do to help.
