Transmission Failure Problems of GMC Sierra

2015 GMC Sierra 6-speed automatic transmission failure @ 1800 miles. As I was decelerating from approximately 30 mph to make a turn into a road the transmission downshifted as expected to low gear. As I accelerated the transmission shifted to 2nd normally. At this point the transmission should have shifted into 3rd gear but the tachometer jumped to 3000rpm before I realized that the transmission had shifted into what seemed like neutral. This left me blocking traffic with a truck that would not go over 20 mph. When I slowed sufficiently the transmission would pick up 2nd gear again. Being close to home I was able to limp home. When I reached home I past my driveway and went to back in as I usually do. The transmission would not pick up reverse! by this time a check engine light came on. I then had to drive about a mile down the road to find a place to make a u turn so I could pull it into my driveway. The truck was towed to the dealership where a mechanic experienced the same problem on a test drive. (he had to push the truck backwards by hand to be able to return to the shop. ) currently the transmission has been removed from my brand new truck pending investigation. It has only to gears 1st and 2nd. This is a serious failure that could have happened while merging into traffic on the interstate. Luckily I was on a back road in the middle of winter!.

The contact stated the transmission failed while driving. The vehicle would not go into reverse. After getting the vehicle home he had it towed to a transmission shop. They found there was a crack in an internal hub. This caused a loss of oil pressure, and lubrication. They replaced all damaged parts. There have been no problems since.
