Drivetrain problem - shudder/ vibration @ 55 - 60 mph

I have a 2000 F250 4x4 that does not seem to run with the same vigor it used to, seems to take longer than usual to shift to the higher gear and also seems to vibrate between the 55 - 60 mph ( smooths out at 70+)

At all speeds it seems like an imaginary very heavy load has been hooked to the truck

Engine seems to run fine, idles fine starts up easy,

What could it be? No check engine lights..

No I have not done any of those, so I dont know what state the carrier bearing is in. I did not notice any shudder when the O/D engages. It seems like there's vibration even when I let go off the throttle, which makes me think its the drivetrain rather than the engine. Does seem a little less pronounced with the leg off the throttle though.

Have you removed the driveshafts, and inspected the u-joints, how is the carrier bearing. Do you get a shudder when the OD engages? How many miles on the truck? The vibration, is it with the truck pulling only, or does it go away when you let off the throttle?
Let me know how that goes!

I am having the same problem with my 99 f350 or was i should say , it started with OD, then it started doing it shifting into 3rd now it has started doing it in 2nd , with the same power loss as original poster has , i was told it was the torque converter ( shutter ) by a couple of shops and this was a normal problem for the Power strokes from 97 to 01 and i am scheduled for replacement on the 26th , i guess my question is has anyone else had this problem and was it a problem as i was told it was ?
