Brakes locking up/ service stability

[Cno01]

I had a similar problem with my 08 sierra 1500 using hypertech but it wasnt the brakes. instead its the tranny shifting very hard but the service stability light flashes too and it starts to run like it miss fires til i hold a rev for like 1 mins. its getting very annoying. took it to a mechanic shop and they said that the stability light comes on when the motor misfires very often. but that doesnt make sense to me. I'm really close to just trading in my truck and getting into something else so i dont have to deal with it anymore. already spent $1200 on repairs and it still doing it.

traction control kicking in maybe? unplug the TC?
