Transmission Failure problems of the 2019 Jeep Wrangler

With only 266 miles on the Wrangler, the automatic 8 speed transmission completely failed while trying to accelerate onto the freeway. It became very jerky and appeard to be down shifting while accelerating. I stopped on the shoulder, turned off the engine. Turned on the engine and attempted to manually shift the transmission. I got up to 3rd gear and then it started down shifting again. I could not drive the vehicle on the freeway and I was lucky to not be blocking a lane which could have resulted in a rear end colission. The check engine light was on. The d on the center counsel was blinking. I pulled over and stopped the engine. I started the engine again and tried to back up a few feet and it acted like it was in neutral and would not move. The r on the counsel was also blinking. I was affraid to continue driving the Wrangler and had it towed to the dealer that sold me the car less than 7 days earlier. It has been at the dealership for 6 days and as far as I know they have contacted the factory for advise on how to repair the transmission. They are waiting for tools so they can begin the repair. This is a 4 door rubicon with the 2. 0 liter etroque turbo engine. I purchased the Jeep new on Jan 30th, 2020. The manufacturing date on the door jam indicates this Jeep was manufactured in July 2019, I think on the 26th.
