2012 Suburban commercial 2500 6.0 gas 4x4
seems like after hitting a substantial bump, traction control light came on. Message reading service traction control as well as service stabilitrac reading on dash. Immediately transmission would not shift out of 1st. Got it home and noticed the shift indicator bar under PRND etc. was no longer on. When shifter is physically in reverse, reverse lights also do not work. After initially shutting the engine off, it no longer cranks at all. I do hear the starter relay clicking but no cranking at all. Any ideas ???
