Oxygen sensors:
bank 1 sensor 3
bank 2 sensor 3
Values are not being returned to the pcm. Could be failed sensors or wiring harness.

Couple of bad O2 sensors gone bad or wiring. Check connections or replace sensors (what I would do) Or go to Autozone or O'Reilly's and they can check with a better OBD reader

Thank you folks for the responses.
I'll check the sensors and connections as soon as as this back pain goes away!!
I forgot to mention that I do not have any cel lights, and Autozone had scanned it but said there no fault codes.
From what I have been reading on this forum and others , I will also need to change my spark plugs and check my cops in addition to checking, the o2 sensors and wiring. Hopefully that will cure that 45 mph shuddering.
The Lisle tool is on its way.
Thanx again

Did a little digging on the number of O2 sensors you should have. You should have 2 on each bank so the #3 failing is because it isn't there. Just to verify count the number of sensors on one of the banks. Normally you will have one before each cat and one after each cat.

Are you in overdrive when you getting the shuttering? I had a similar problem last year: shuttering, overdrive - around 45-50 MPH, I could recreate it going up certain hills. No Codes. Problem was COPs. I had already replaced 3 within the prior year because I would get a misfire code and knew which COP to replace, so I went ahead and did the remaining 5 all at one time. Problem fixed.
Point is, you can have an intermittent/bad COP and NOT get a code set.

This happens a lot and is often mistaken for transmission shudder in general not just on these trucks. I would def look at this first. I replaced one COP and think I have a couple on their way out but no codes now. The had to get to the point of misfiring badly to throw a code.
