Automatic Transmission Control Module problems of the 2014 Chevrolet Impala

I have taken it in on several occasions and been told there is no active code. My transmission control module constantly looses communication. Through my research I have found numerous accounts of this part failing and gm not repairing it, nor issuing a safety recall. I took the vehicle in and was told it was a common failure. The failure of this part has put myself and my children in danger, the computer failure causes the car to randomly shift gears while driving jerk violently and completely shut off at times. Currently it is stuck in 1 gear. I am a single parent, I am scared to travel with my children in the car, anywhere including school and medical appointments. This issue happens while driving the vehicle at all speeds including highway speeds. The last time I took it in the dealer stated, the vehicle was not safe to drive they notified my warranty company, which took 2 weeks to look at the vehicle at which time I was told that the fault code was not active but only in the history of the computer and they refused to repair it. Being that this is a known issue by gm I believe a safety recall should be issue before someone is hurt or killed, if they havent been already. The service advisor informed me that they were instructed to clear the codes from my obd let the car sit and see if the issue returned. This issue has affected multiple gm vehicles yet they refuse to make the repair necessary to make the vehicle safe. Questions; 1)tcm fails, yes it is available for inspection. 2) vehicle randomly shifts through gears including park, at all speeds. Causing car to jerk violently, shut off or get stuck in 1 gear. It has shut off while traveling at 75 mph on the high with my children in the car on multiple occasions. 3)yes at covert chevy in hutto, TX. Even the service department was scared to drive it. 4) I dont know what the dealer inspected. 5)yes service stabilitrack and power steering and check engine light with code u0101.
