My 1990 240 is vibrating when I get close to 50mph, it pretty much disappears when I reach 60mph. It was doing it only while going at that speed. Now I also notice the vibration when I let up on the gas from that speed. I have already replaced the transmission mount. The rubber around the center bearing looks good. Could the torque rod bushings be the culprit? (I just replaced the wornout trailing arm bushings.) How about the transmission? (it got down a couple of quarts when a cooling line wore through.)
