NHTSA Complaint #11550892 — 2019 FORD EXPEDITION

The 10R80 transmission started delayed shifts between 8,9,10. After 50 miles the issue spread to the lower gears. When going from 3rd to 4th or 5th the engine speeds up vehicle loses speed. To recover let your foot off the gas and then apply gas very gently. After another 50 miles shifting became more erratic, sometimes with a load clunk. My safety has been at risk because you cannot count on the vehicle to do a smooth acceleration during a traffic merge. If you are in a lineup doing a merge suddenly you cannot keep pace because the transmission is shifting erratically. The vehicle has been at the dealer from October 3rd within in line for repair. They have stated Ford is just overwhelmed with 10R80 repairs. Based upon public information the Ford 10R80 transmission has some major flaws. Received an orange wrench message telling me repairs are required. I know that by its behavior. Filed a case with Ford Customer Care program, so far no help.
