Transmission Slip Out Of Gear problems of the 2008 Ford Edge

While driving in the city it jump from first to second gear with a hard boom. Driving on the highway while going up a hill jump out of gear and will not pull I pull over to the shoulder. To get the car to function again I have to turn the Ford Edge off turn it back on this is not good. What can be done to fix the problem.

2016 driving out of subdivision,came to stop before starting up incline. Motor was racing but car was slowly moving,drove a short distance,at very slow movement. Pulled off road and had car towed to Ford dealership to have it checked out. They found nothing wrong. 2018 after hwy. Driving and then turning road. . . Came to stop sign,put foot on gas to make turn and car motor was racing but car would barely move. Moved about 8 feet then put gear into neutral for a minute and then put gear into drive. It made a loud noise , but did go into drive. Drove 1 block and it apparently slipped out of gear and rolled to a stop.

I bought my 2008 brand new. At 39,000mi I took to dealership after noticing the transmission lagging, slipping, loud very hard shifts. Also was parking at the grocery store when I pulled into spot, with foot on the break car lurched and engine reved. If it hadnt had my foot on break it could have hit someone. Of course dealership couldnt replicate, was told to bring back when it didnt it more regularly. At 59,000 I took it back in after sever times of loud/hard shift and jerking like I had been rear ended by something. As well as being on a road trip where it felt like it slipped out of gear and the wrench light came on. I pulled to side of road and called Ford. They said to turn car off and back on. Wrench light went off and car seemed fine. Then while on interstate it reved really high again but car felt like it was in neutral, it wouldnt accelerate when I pushed the gas. Pulled off again and cut off and back on and it seemed fine. Dealership was able to replicate, but results inconclusive. Was told to bring back if happened again. At 83,000 it is back in, it has been loudly shifting with the big jerk like before this time more frequently and also was coming off exit ramp of interstate and at stop light, car was in drive,but wouldnt go, felt like it was sitting in neutral again. Dealership has had it for 3 days and found metal shavings in transmission. Will not confirm this is covered by warranty even though it is an existing issue. Can not promise for will honor repair. Wants to rip out my transmission to see what problem is, but wont give me any kind of estimate as to cost. Only said Ford would "assist" but couldnt tell me how much. I have read hundreds of similar issues online of the exact same issues. Seems like Ford would have recalled this already. This is not only an issue of a faulty tranmission, but also a huge safety issue as well.
