Is the 10R80 fatally flawed?

First off the DCT is not the same 10 speed transmission that's being installed in F150's. Not really sure what relevance the DCT trannys have to the 10R80 in our trucks except the number of gear shifts?
IMO it's apples and oranges comparing the 2 different transmissions when it comes to failure rates. Just saying..........

The point I was making is that they put millions of faulty DCT transmissions in the focus over a 6 year period. They never fixed the problem. They never made it right. And now, they are going to pay dearly for it. I consider this a "fatal flaw". I consider something fatally flawed when there is a systemic problem that plagues a system to a point above and beyond what a reasonable manufacturer would consider acceptable. In manufacturing we call this Six Sigma. The maturity of a manufacturing process can be described by a sigma rating indicating its yield or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects (3.4 defective features per million opportunities).
So... Id do a little more research before you add something as fact that is simply not true.

Well, if you take the time to carefully read and understand what I said, perhaps you would understand... I was in no way making a case for them being the same. Where you get the erroneous data that "the number of gearshifts are the same" i have no clue considering the DC is a 6 speed. I guess you may not know much about the architecture of these transmissions.

OK so my update on this. I took my truck in yesterday to the dealer for the transmission clip recall where in Park it may not actually be in Park and your rig will rollllll away. My clip is in place and all is good.
While there I asked them about TSB 182079A (rough shifting when cold usually into and out of 3rd). My build date was Jan 11, 2018. The TSB was for rigs built August 1, 2017 and earlier. They said they'd look into it. When I got it back, the SA told me that they plugged it in and no codes, no issues BUT they did, "UPDATED TCM, CLEARED CODES". This morning I jumped in and upshifts as well as downshifts into and out of 3rd were noticeably smoother. It wasn't a huge issue initially but figured what the heck and asked them to take a look. So. My suggestion would be to ask them to give it a look and if anything update the TCM, clear the codes. It's a .3hr operation with zero parts involved so should either be done for free or for .3hrs of labor - should be reasonably priced.
Will update this over the next few weeks if I notice any major changes to the transmission, cold shifts, etc... Again this is a 2018 3.5 EB with 10R80 transmission.

One of the dealers i called said an hour plus shop supplies. I asked what supplies are needed to plug in a electrical connector? he hung up lol.

Want to know what this transmission is about? Here is some light reading material about the design and function of it. http://www.thetruthaboutcars.com/tag...-transmission/
The truth of it is that the ratio spread is not that much greater than the 6-speed, but it has more gears to keep the engine in it's power band whether you are towing, performance driving, or looking for fuel savings. Also, being co developed and shearing it's guts with GM units, it's shown that it can be programmed to shift faster than Porsche's PDK units, like the ones in the Camaro.

Still curious as to which 6sp is actually faster than the new 10's. Or even GM's older 8. I mean I get it - I sort of like to stir a stick too. I do - even had one for a while. I hate them in city traffic though - HATE.

2018 XLT 5.0 crew version with 10sp trans , bought new Sep. 2017 and currently with 11500 miles.
Have an appointment with the dealer this coming Thursday for whining noise and erratic hardshifts.
The noise only happens when the torque converter opens and the transmission is hot and it's becoming louder as the time goes...
No way it's normal for when the transmission is cold this noise doesn't exist.
The hard shifting is more frequent when the transmission is hot but it is really erratic.
Downshift:
Sometimes the transmission is hot and is shifting ok but then when you come to a stop it downshifts so hard that you have the impression the torque converter was closed and the transmission downshifted regardless, I think if I was driving on ice it would lock the rear wheels. After cruising coming to a stop I can "feel" every downshift, it's really anoying.
Upshifts:
Sometimes when accelerating in normal mode it seems that you are in sport mode for you can "feel" every single shift. Crusing is annoying too.
My truck is affected by the recall but I really don't believe it's a problem only with program for I did erased the adaptation one time and it improved a little but it didn't eliminate the torque converter noise and the hardshifts came back soon after....
I think together with the programing, there is a problem with the pump or the torque converter in a such way that they can't keep the shifting consistent so for the same command the pump/torque converter will give different shifting points in some cases shifting right and in some cases hardshifting what would lead to the adaptation getting totally wrong....
The whining noise really sounds like a pump cavitation for lack of fluid or something.....

My tans and rear end are not right either.
Do you have any update on the whining noise with your trans? Is it worse? I have the same issue, and I'm starting to think that it sounds like pump cavitation as well.
