Hey Scotty. Just recently discovered your YouTube channel and I’ve been watching a bunch of videos. I have a 2019 Ford Edge Titanium with around 94k miles. For the last 5k miles or so under normal acceleration the car judders after it gets out of the first couple gears usually from 20 mph and sometimes it’s pretty consistent and then sometimes it’s hardly noticeable. I took it to a local place here in White Bluff TN and they replaced the spark plugs but nothing changed and they said they found a recall from Ford with that scenario and they don’t have the proper equipment to view the raw data. The Ford dealers are backed up to over a month out and they want you to drop your car off for at least a week to even get to it. I was wondering if you could think of anything I could check or have done? It doesn’t feel like it’s a transmission issue. Also, a few months ago I got a code for a O2 sensor but it went away a day later and there hasn’t been any codes sense then. Thanks for your help!
Clarification: What powertrain do you have? Is it the infamous 6 speed wet dual clutch?
@dan according to wiki, all 2019 models have a 8F35 8-speed.
@mmj I think Wikipedia might be wrong, the 2.7L most definitely doesn't have an 8F35 (it's rated at only 350NM, even less than the DCT that's rated at 450), it probably has an 8F57 (which can handle the 515NM, and is not mechanically related to the 8F35)
So the transmission type probably depends on whatever engine is installed...
Consider the source: Wikipedia is owned by Google and we all know how accurate they are. I'll put my money on @mmj on this one.
No, but they are financed by Google, to the tune of $7.5 million in the last ten years. I wonder why.
@doc because they have a partnership.
Anyway never trust a single source. Not Google. And especially not the hacks at Wikipedia.
@doc Wikipedia is the public encyclopedia, anyone can write there anything he wants.
The most protection they offer is that on some topics you have to sign it (anyone can create a wiki account for free)

Since most of the euro market had the MPS6i as the default gearbox until the 2020MY, and since the 8F35 gearbox can’t handle that much torque, whoever wrote it is definitely wrong

shutter under acceleration ... the car judders after it gets out of the first couple gears
A shudder is like when a chill runs up your spine.
So is this a single pulse, or is it just a constant vibration?
It’s a repetitive small jolt that if I keep the gas petal at a constant pressure it will just keep doing it over and over. I already had the spark plugs replaced and the mechanic told me about the service bulletin that the other person below mentioned. The only thing is that it will do that jerking motion past 35 mph. If I watch the rpm’s at highway speed you can’t feel it anymore but you can see the slight movement in rpm’s. Also, under heavy acceleration it doesn’t do it as much. Finally to answer another person it is the 8 speed transmission. Thanks everyone for all the quick responses so far.
that could be an engine misfire (see our FAQ page).
Do you have any warning lights on the dash?
If your car has the 8 speed automatic transmission with a 2.0L, you probably need a software update.

If it's an AWD car, the AWD system can also cause a shutter and need a software update.

And in general there's a lot of things that can go wrong with Ford's 8 speed auto.
If you have a 6 speed dual clutch (which you probably do not have, they seem to only still market them in Europe),
there's also a lot of reasons why it can shutter, but usually it's the clutch pack.
This sounds suspiciously like the old Chevy torque converter shudder.
