Weird Shudder/Vibration
So I have a 2001 2500 4x4 QC CTD.....I have only owned it about six months but there is a issue that seems to be progressively getting worse. MAINLY on the freeway, when I get into it really hard I get a VIOLENT whole vehicle shake, if i let off of the gas it immediately goes away. It seems to be aggravated when I have my Edge Comp box on, but will do it at a much less level even without it. It also seems to do it with the shift going into its final gear. I have become a pro at feathering the pedal to keep it less noticable but if I harp on it it feels like the truck is going to shake apart. Once cruising along never feel a thing...smooth as can be, once a hill comes up and have to give it the gas comes back again until i let off. In the city have NEVER felt it even if HARPING on it, it seems to me has to be in a higher gear to feel it. I know this topic has been asked but it seems every scenario is different, so i tried to be very specific with my particular situation. No other shifting/vibration issues other than this one.

Check the u joints in both drive shafts. If there is any play replace them. Turn overdrive off and see if the vibration is still there. I am leaning toward the torque converter clutch is slipping on you which would require replacing the t/c. Might try a trans fluid/filter change.

Also check your tires for any bulges or tread separation

I'll bet it's torque convertor shudder. You need a convertor. On my 01 it shook so bad the dash vibrated. When you let off the throttle the convertor unlocks. I knew my tranny had been rebuilt a few years earlier so I bought a single billet convertor and installed it myself. Problem solved. Don't waste money on a stock convertor, they were marginal stock, and with any programmer at all they will fail.
