Take the truck for a test drive. Make careful note of when the shudder is most felt. If it's right about 45mph, when the trans shifts into O/D, you likely have a slight engine miss. (tune-up, plenum, etc.)

That's right about where it is felt. It will do it in 3rd and 4th when the TC locks up. It has new plugss, wires, cap, rotor, air filter, throttle body cleaned, plenum replaced, front O2 sensor. Not sure what else to look at.
Have you reset the PCM lately? (like, sometime after all the parts were changed? )
What brand O2 sensor?
I have not manually reset the pcm. The last thing I did was the plenum and the ground was disconnected from the battery for a week or so. Not sure if that would reset it. O2 sensor is a NGK.
One of my buddies has one. We were going to check the plugs again, so we will check the CPS too. Part of me hopes it's that so I will finally have an answer. The part of me that would have to install it doesn't want it to be that...it's quite the pain.
