See my signature. Follow it to unlock your cluster and start monitoring your voltage. Pay attention to voltage when you go into failsafe mode. Also a proper Scanner like dis or Inpa would be able to show an error for voltage spike and trans failsage at same time. So you can diagnose it that way as well.

I ended up replacing my voltage regulator and all has been well in the hood since then. Obviously my battery was also destroyed and replaced pretty much same time. I was actually getting overvoltage, not under voltage.
