NHTSA Complaint #11692430 — 2020 FORD F-150

While driving on the interstate doing around 70 MPH I I Stanton drive up a fairly steep hill on the road . About half way up the truck down shifted from 10th gear too what it said was 7th. The gear did not engage and the truck revved up like it was in neutral. I pulled over immediately. Checked under the truck and no leaks. Got back in and truck ran like normal. Went to the dealer and was told that is a common issue with this particular transmission. I also have noticed when driving and coasting too a stop when the truck downshifts there is sometimes a loud clunking sound. Ford needs to be help responsible for putting trash transmissions in these vehicles. Please advise them to issue a recall and repair or replace them.
