Tranmission Failure

great info here , thank you all

Just took in my 22 gen 3 on 35s with 23k mile in for transmission and they told me today that they have ordered a new transmission. The truck started to have hard/harsh random downshifts and Saturday it became consistent.

Mine runs very well as far as transmission shifting , I have Gooses TCM program . Biggest thing I see is the adaptive learning , Some days I drive like I was 16 again in my moms Pinto , other days I drive like the old man that I am . Boost stays in vacuum the whole trip . I think that really messes with adaptive table , every so often i reset the TCM learning on accesport and can tell a difference right away . This is on a GEN 2

When I did the reset the transmission table through FORSCAN is says "reset meaured slip time" or something in that line.

My logical brain says that its "learning someone's driving habits" is bunch of horse sh**. It can't and it would be stupid to do so. Since no two people drives the same. So Ford, and other brands" would get constant complaints of how ****** it drives when a house has multiple drivers.

So if anyone paid attention to the reset transmission learning table dialog, it reads me to believe that all it's doing is adjusting the slippage of the clutch and adjust it according to the specifications. Which benefits several things. It makes shifting more consistent even with manufacturing variences of the transmission parts. It also makes the wear of tear of the internal components consistent on different vehicle.
I recall one Ford released video where it stated the adaptive learning extends the life of the transmission. If it can learn the transmission slippage, it can adjust the slippage time to maximize wear and tear.

Just think about how complex, if even possible to adjust for; driving modes, drivers habits, weather conditions, speeds. Too many variable's to make it "adapt".

It also explains why after reset it drives "better" , "smoother", because it's starts with long slip time, and gradually adjust it to shorter to maximize longevity, or what ever goal Ford is looking to achieve.

All my resets have same results. Great for 500 to 1000 miles. Which during the time gradually turns to shit. Especially when you have a CDF drum issue. Which I had on my
Other 10R80.

PS. I have yet to see actual Ford transmission engineer state otherwise. If someone know please feel free to share.

what can be felt in transmission when we have potentially a CDF "syndrom" ?
At time, on my 20's , about 35K miles , never done a" reset learning" and everything seem smooth/well

Mine basically had this momentary "loss of power" on 3 to 4 or 5 up shift. Started as occasionally, then after about 6 months it was every shift. Could replicate it on manual mode shifting from 3 to 4. It's about 1 second of complete loss of power. As if you pressed the clutch pedal in.

But no slipping on manual mode on any of the gears.

Resetting the learned transmission only helped in the beginning, and after about 500 miles symptoms came back.

Then one day it just started shifting erratically on the freeway and had to be towed to trans shop. $11k out of pocket expense.
