2020 Ford Transit Power Train

We started experiencing slight transmission shifting issues in early-mid 2024. More issues in December 2024/January 2025 - this time it was really hard and jerky shifting. It was sporadic at this time, but it was often. My wife and I have 7 children. This vehicle is usually driven by my wife to pick up kids from school, run errands, etc. At the beginning of March 2025, my wife was merging onto the highway, but it didn't want to shift. She stated that a big rig was coming behind her and the van was not shifting and picking up speed. She said the engine was revving but just was not shifting up. She said the big rig honked and had to change lanes or else he would have hit her and my kids. Several seconds after the big rig passed was when the transmission hard shifted and jerked and it began to pick up more speed, but from that point on, the transmission was not operating properly. We have not driven it since March 2025. I have been saving up to fix the transmission, but I read so many other Ford owners have the same issue with this particular transmission. The Ford dealer confirmed it had a TSB on this exact issue and that many other 10r80 transmissions were doing the same. The issue was reproduced by the Ford dealer. It states the CDF issue in the invoice. There were no warning lamps or messages prior to the experience merging on to the highway. I reached out to a local independent mechanic and he upgrades the parts in these Ford transmissions all the time - proving it is a very common issue. This is a huge safety risk for anyone operating or riding in a Ford with this transmission.

Only I have 88,000 k on 2020 transit the transmission have problems with shifting while driving on highway start with delay on 2nd gear now fault code for gear 10

Driveshaft both front and rear failed as pieces broke off while driving at different times requiring tow and repair

Loss of power while driving with no warning. Almost crashed. Shifting violently. After a few months it wasn't safe for anyone and was happening all the time . It's at the dealer getting the transmission rebuilt with re engineered parts . That's what the dealer told me . He said this will resolve the problem for good . 8000$$ 67k miles ford is not helping with cost. Ford had to re engineer the parts that are going in my van , isn't that them admitting they have a transmission that was no good from the start

A few months ago, my 2020 Ford Transit had a transmission issue, and the dealer replaced the torque converter. Now, at 101,300 miles, I’m experiencing loss of power, jerking, and rough shifting, and I have to replace the entire transmission. After researching online, I’ve found that many others have experienced the same issue.
