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.

Car has 49700 miles. I was traveling on highway at speed and tried to accelerate to merge into exit lane traffic and engine and power train completely cut out and transmission failure light with wrench came on. Luckily cars behind me were able to slow down and avoid an accident but this could have been deadly. Thank God my children were not in the car. Car was previously taken to dealership in January of 2023 for transmission shifting issues and repair work was done. Car is also -??hard shifting-?? into gear from park, causing whole car to jerk. Car routinely -??hard shifts-?? when accelerating onto highway and -??hard shifts-?? when slowing in rush hour traffic.

The transmission in my 2019 Ford Expedition is slipping and having drastic gear changes. Other people with the 10R80 transmission are having similar issues. This car is unsafe to drive.

Event occurs when vehicle is warmed up - transmission fluid temp > 205 and more likely to occur going uphill or on a slight incline on highway with a speed above 55 mph. When accelerating quickly or aggressively, the 10 speed transmission fails. I push down on the gas pedal while in the 10 gear. It seems like it is stuck in neutral, the engine rev's to the red line if I leave my foot on the pedal, the vehicle looses speed and eventually finds a gear between 2 and 6 and transmission re-engages. The vehicle will rev to the red line before finding a gear. This has created multiple dangerous situations in which a vehicular accident almost occurred due to the immediate loss of speed in highway traffic situations. The vehicle went from 83 mph to 55 in seconds before the transmission re-engages. I have take the car to the dealership twice and they can not recreate the issue in order to fix despite submitting numerous videos of the separate times in which the event occurs.
