That is also true.

Ok great, thanks! Guess I will have to take it for a cruise today- hopefully it acts up as it seems to be hit and miss when it does.

Ok so that worked out! Took it for a drive, and it acted up again. So went home and pulled codes, I got 628 KOEO (CM), and 111 KOER.

so would it just be the TC solenoid or the TC itself? Any ideas? Would a bad TCC solenoid cause the shuddering/engine trying to stall/whining noise/hard 1-2 shifts, or is the TC completely toast? I talked to the guy that works at the NAPA in town (used to be a mechanic), and he said hes mostly dealt with the solenoid failing, rarely ever the converter itself.

Another one of those strange names Ford comes up with, right up there with Profile Ignition Pickup (PIP) and Differential Pressure Feedback, Exhaust (DPFE)!!

OP, do the symptoms go away when lightly touching the brake pedal? Try it out... hold your speed steady with one foot and just barely push the brake pedal with the other. All you want is to activate the brake lights, which also signals the computer to disengage the converter clutch.

Sorry, my internet has been down- yes, the symptoms seem to go away when going at a constant speed and then toughing the brake

The term continuous memory was coined by Hewlett-Packard (HP) in 1976 to describe a unique feature of certain HP calculators whereby the calculator could internally sustain most, or in later models - all, of the contents of user memory (via battery-backed CMOS memory).

Fords definition of Continuous Memory:
Continuous Memory: The portion of KAM used to store DTCs generated during Continuous Self-Test.
Continuous Self-Test: A continuous test of the EEC system conducted by the PCM whenever the vehicle is operating.
Keep Alive Memory (KAM): A portion of the memory within the PCM that must maintain power even when the vehicle is not operating.

I know that the Ford manuals call it Continuous Memory but that does not describe what it is. If you remove the battery cables the codes are lost so that does not fit definition of Continuous Memory to me. The PCM computer does not have a little battery to keep the memory.
Ford should have called it KAM and not CM.

Besides the novice better understands it if you call it computer memory.

So since the shuddering goes away when the brakes are touched, does that mean the TC is still good? Could it be the solenoid? Could a bad VSS be causing these issues? My CEL does not come on at all though.
