Transmission Failure problems of the 2021 GMC Sierra 1500

I own a 2021 GMC Sierra 1500 at4 with the 3. 0l duramax diesel. The vehicle developed severe transmission problems, including harsh/jerky shifting and a hard clunk when shifting into reverse. The vehicle was subsequently diagnosed with an internal transmission failure. The repair facility informed me that the transmission gears had failed and caused damage to the transmission and stated that the failure appeared to be related to a manufacturing issue. The repair facility also advised me to watch for a future recall because they believed this could be a widespread issue occurring in other vehicles. I am submitting this complaint so the failure can be documented and considered along with other reports of transmission failures involving this vehicle. Note from autoshop:transmission failure was due to a manufacture design flaw, not due to the customer's driving habits. The pump original design is with slanted gears and the gears are forced away from each other and placing too much strain the bearings ani the bearing fail. An update performed to have straight cut pump gears to avoid bearing damage. Cdf drum and center support changed to updated parts that are heated treated to avoid damage.
