NHTSA Complaint #11697035 — 2020 FORD EXPEDITION

2020 Ford Expedition FX4. Towing a four wheeler and motorcycle on the expressway. The suv was in tow / haul mode and on cruise. The car downshifted to go up a incline and made a booming noise and then composed its self. Shortly after, I tried to pass a car, and the trans downshifted, made a couple of loud clunks, shuddered, lost all power. After a couple terrifying seconds it composed itself, found gear and maintained speed, acceleration was not possible as the trans would go out of gear. Further down the road, it did the same thing, clunk, clunk out of gear, no power. There were NO warning lights. I took it out of tow mode and tried both sport and standard settings, both had similar issues. This was the scariest situation I have ever been in with a car mechanical issue. Note: We were ~120 miles into the 160mile trip. The OAT temperature was ~45 degrees. Trans temp showed 250 degrees when acting up, and dropped to 220 by the time the trip ended. Odometer shows ~77k. CPO, dealer maintained.
