We just had a truck with service brake system and a no-start problem along with a bunch of other problems. Seems he killed his TCM trying to jump-start his truck. I watched it happen, not sure what he did but he did make some good sparks and got the end of the clamp on the cable to glow pretty good. His gear selector wouldnt light up either.
If it got that hot, he must have reversed the cables.
