I had the exact issues you stated. Did a transmission oil, filter change nothing changed. Changed valve body, and reset TCM, slight change. Ended up needing a transmission rebuilt. It had a bad CDF drum seal and a few other bad parts. I now don’t even notice when it shifts.
Mine was not under...
Appreciate the thorough research.
As far as the shop programming the new valve body, I am just taking his word for it. They are highly recommended (30 years in business.) 4.9 google rating (100 reviews), and he stated he has done multiple valve bodies in 10r80s.
Also after picking it up it...
The 2 part numbers are different
Expedition is: JL1Z-7000-F
F150 is: JL3Z-7000-F
I can’t seem to find what the actual difference is between the 2. The f150 transmission already has the expedition valve body on it, expedition bell housing and Torque Converter.
If that helps any.
Does anyone know if a 2018 Ford F-150, 4x4, floor shift, transmission will fit into a 2018 Ford Expedition, 4x4? Can’t find a concrete answer anywhere.
Thank you!

Already did, drove it around town, same weird shifting as before but no overheat (only drove it on back roads no highway.) I don’t want to get it back and have it overheat again
Would a bad cdf drum cause it to over heat?
Ford transmission are on back order till mid-end of April unfortunately. The used one I have has had the CDF drum already changed by the dealer at around 10k miles.
Any idea on cost to change out the CDF drum?
No warranty here. All out of pocket
Short story: after having my valve body replaced ( along with fresh fluid, filter, tcm reprogram.) less than 100 miles later, was driving on highway and noticed it wouldn’t go into 10th gear after multiple tries, few Seconds after “powertrain malfunction” displayed. I pulled up transmission temp...
