I’m going to have the speed sensors checked out. Now the park is going out in my transmission.... put it in park on any kind of incline or decline and it rolls on it’s own and you can hear the transmission clicking.

I have 2017 Silverado 1500. At 72,000 miles I had to replace the transmission. Replaced it with a brand new (not refurbished) GM transmission. After it was replaced I was running late to work and was driving 95 - 105 mph. The service stabilitrak came on and I lost almost all power. No cruise control, traction control light came on, and no indicator for transmission position. I pulled over and killed the truck for a few minutes, cranked back up and was fine for about another 10 miles then the same again. While trying to drive with the service stabilitrak on, I had my foot to the floor and could barely do 65mph. Went back to the shop that replaced the transmission and they couldn’t figure out anything. This has happened multiple times now over the last 20,000 miles. PLEASE HELP!!!
