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..

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?
Motor performance can definately affect tranny shifting, along with cold temperatures. Tranny fluid level full, any fuel related issues? A CPS starting to fail can cause performance issues.
