2020 Ford Expedition power train problems

“When accelerating hard, the vehicle attempted to downshift the transmission, but failed and all power was suddenly lost. Vehicle transmission was loud and grinding. Warning lamps stating Shift failure was displayed but disappeared quickly. After removing acceleration, transmission seemed to slip into gear and normal acceleration was restored. About 30 seconds later when holding constant speed, vehicle suddenly jerked and downshifted unexpectedly, again grinding could be heard and RPM's shot extremely high. Again foot was removed from acceleration and normal driving was restored.”

“My car is a 2020 Ford Expedition Max with under 39,000 miles. A major transmission issue was just discovered while getting the 40,000 mile service. I believe it is the same issue as described under Recall 26S48. The car suddenly shifted into Neutral while driving on the freeway two separate times. The car is currently at the dealership, they got a P07E code, but did not experience the issue themselves.”

“The 10 speed transmission has ALWAYS slipped and never shifted correclty. Taken to shop multiple times and was told thats just how the transmission changes on the newer Ford 10 speed transmissions. Had the car 3 years and now I got a code saying the transmission is slipping in between 9-10 gears and 3-4 gears. The truck has ALWAYS done it but now it's gotten worse and no WARRANTY. Looks like THOUSANDS or millions have this problem and no clue how I'm responsible for a faulty transmission Ford knows is bad on their side. Terrible customer service where this is not fixed under a recall until the warranty is out and UNABLE to fix now. UNACCEPTABLE! If Ford would've fixed it earlier before it was completely gone, I'd have my $10,000 back. And why does Ford have a transmission that most transmission shops will not work on and costs that much money to replace. I'm DONE with Ford and their products!”

“When the vehicle is in motion, the transmission shifts very hard (with a loud audible "bang") between gears 4 and 5, and intermittently power is lost to the wheels (again, while the vehicle is in motion, you depress the accelerator, the engine revs up, but the vehicle does not accelerate). Once you brake and come to a stop, the vehicle accelerates properly again.”

“Was trying to merge into traffic by accelerating but the transmission was not shifting properly or slipping which caused me to almost be in a wreck due to this problem. Took vehicle to dealer and was told the transmission needs replaced due to a cdf drum inside transmission. Said there is a tsb for the issue but no recall. Said it's a known issue but I have to pay for a new transmission. Also have issues with the park brake setting while still moving which will also damage the transmission and there is a recall for that but no remedy yet. Why would I put a new transmission in and pay for it when it still has the park brake issue that will damage the new transmission. Afraid to drive the vehicle with these problems but paid a huge amount of money for it to just sit in the driveway”

“In 2025, our 2020 Ford Expedition had harsh, erratic shifting, then would lurch during shifts or lose power. Ford service replaced the valve body plate and reset the transmission software. This did not fix the harsh shifting; it only cleared the warning lights when the harsh shifting occurred. Now in 2026, shifting and gear sticking have continued to get worse, and now Ford says we need a new transmission, but it is now conveniently out of warranty. This is an issue the dealership was not transparent with us about; it is a safety issue when driving, and now the costs are intended to be completely out of pocket for us.”
