Diesel Engine problems of the 2020 Ford F-250

Motor has a nkocking tapping sound like and old school type writer and gets loud at times when ideling and some time really loud anfter driving it fo rw whlle, (diesel engine doesn't sound like that),Ford engineering at factory knows what the problem is but refuses to allow dealership to repair it and replace the parts. Transmission had snecor and valve body go out caused transmission to lock up in 10th gear and stalling out. Dealership replaced the parts with new ones, bu tdid not correct the problem and now stalles and slippes when shifting gears, or sometimes shifts so hard it shakes the truck (f250 diesel). Has a grinding noise when down shifting from 5,4,3 gears. When drivining the truck and go to pass around another vehicle is slips gears are stalles down until it can catch its gear to go happened several times. Vehicle only has 6,500 miles on it and was purchased August 26, 2020 and should not have these issues and problems. Most of all the factory engineers should not deny the dealership to fix and replace what is wrong and cauusing the lound and upnogchis knocking ticking sound even after doing a black box flight recorder to determine where the problem is coming from. They said to keep driving until enough complaints com in to have a recall sent our are until it brakes and goes out. This is a safety hazard to everyone on the road and could possibly cause harm to inisant people, such as myself, my family, and others out on the road. Please have this looked into and help get it taken care of.
