trans vibrates ?
i have a 99 f350 auto 7.3 cc drw truck that shakes at 40-45 mph. it will drive up to speed no problems. it shakes around town when i get up to speed then let off and then go to throtttle to stay around 40 to 45 it shakes, goes away above 45 or when od is shut off. i just changed fluid as found on this site with flushing converter. any ideas?

It could be a bad center support bearing in the transmission. When I rebuilt my trans a few yrs ago, I found the cage in the bearing shattered and the center shaft was wobbling causing wear on the end of the direct drum. I felt a vibration as you described and it went away after the bearing was replaced and the rebuild done.
