Vibration at speed over 60 mph? on 1998 Mercedes-Benz S500

This car develops a vibration over 60 mph when I begin to ascend a slight rise in the road. I cannot use the cruise control because of the shaking. I have been told that I need a replacement transmission and a new torque converter but my sense is that the transmission is fine. What does my car need?
