2019 Chevrolet Suburban Driver Assist & ADAS Problems

Electrical: Noticed a few months ago that the lane assistance/departure and blind spot warning work off and on. At times the blind spot warning does not warn and will when there is nothing there. Lane assistance and departure have the same issue. Transmission: Gears slipping. I am not a mechanic but there were no telltale signs until it just went out on me while driving with my children in the car! The only thing I noticed in several months prior was that the vehicle would shake as if you were running over the paved warning bumps on the side of the freeway. I just thought it was possibly the road or I needed new tires. I got new tires, problem still persists. When the gears slipped while I was on the highway it took about 15 seconds to engage at which time I removed myself and my children from being a traffic hazard. I checked the transmission oil - which I just did two weeks ago because I knew it was time to change the oil for the transmission - this time it had a very defined burnt smell and black in color.
