Haulin Bass!
A way to test is to turn your T/H on, stomp on the gas to gain about 20mph then left off the gas completely. You should notice that the transmission does not shift up immediately. It will stay in that lower gear in the powerband anticipating you getting back on the throttle. It also sets the shift points a bit higher in the RPM range.
At least that's what it does on my truck.

Here is a video of my ecoBoost shuttering. It's difficult to capture how bad the shaking is on camera but you can get an idea by listening to the engine and watching things vibrate. (These details are most noticeable in 720p)

This shaking is likely moisture related and only has occurred after driving through very heavy rain.
Following this video I immediately went to the dealership and they pulled engine misfire codes. After talking with Ford, the dealership informed me Ford was aware of the problem and working on a fix. Until that fix is released they aren't allowed to even look at it. I left that dealership and within a half hour the shaking came back. I called the dealership and was told to just keep driving because there was nothing they could do. I asked about causing further damage to the truck (catalytic converter, motor mounts, etc...) and was told there was absolutely no damage being done and just keep driving. This time the shaking got so bad I was unable to safely keep up with traffic and had to pull over to the side of the road and wait for the rain to stop. 30 minutes later the rain had stopped and things were starting to dry up so I resumed my driving. No further problems for the remaining 200 miles home or in the 3000 miles since. (Except for a catalytic converter I had to have replaced two days later. Although I'm "told" this had nothing to do with the unburned fuel and water that got dumped into it...)
Is this the shuddering that others are experiencing or a separate unique issue?

Much faster speed/rpm than where I see it. Sometimes just a single jerk or two and then other times the engine seems to get confused and goes berserk. Also mine has done it in low humidity - or at least not raining super high humidity.

It almost seems to me like this is a special version of shuddering where you're just inhaling water and misfiring. Doesn't seem to be related to low rpm, 55ish. Was there even an uphill grade involved?

That may be true but the torque converter used to unlock the second I pushed the button. I used this while trying to determine if it was a slippling torque converter or another issue causing the shuddering since October 2011. Now it doesn't unlock when I push the button. It could have been a glitch in the original programming before my recent tsb flash.
Any other feedback since latest flash? Has everyone else with the shuddering Lemon Lawed theirs?
4 days since the reflash, the shuddering is not as noticable but still there 65-70 mph slight acceleration. I won't be certain until I get to a slight grade road without expansion joints. I'm hoping it is learning how to tailor shift points and other parameters to completely eliminate the surge/shudder sensation completely. 9000 miles until 24,000 miles and lemon law option goes away.

Late to this party !
I'm a retired Ford engineer, so I have some background.
If your shutter/misfire issue can be correlated with any type of water/high moisture conditions (fog or even very high humidity), then your problem would be with the crank shaft or cam shaft position sensor/connector. In "the old days" (EEC-I, II, III, IV) those connectors were packed with silicon dielectric (because we all knew there really was no such thing as a waterproof connector). Of course some bean counter thrifted that out.
This could be a simple and quick fix.

Hopefully the existing Ford engineers have some background as well. They've had 1.5 years to resolve this problem therefore I don't think it's something quite that simple especially considering the TSB's haven't called out for giving customers a tube of dielectric grease. Instead it feels like they've applied vasoline to the customer's behind.

Sounds so simple! Right on man. I guess all of the engineers at Ford now must be totally inept. All that schooling and no common sense. It's a shame. It also seems that all that education dosen't cover the fact that a "shutter" goes on the windows of a house (or in a camera) and, a "shudder" is a shake.
