Installed 2006 6.0 out of escalade with 4L80 about a year ago. PSI harness, stock pedal/module assy and stock ECM. Yesterday on freeway lost pedal response. Engine running, but no power. Pulled over turned key off and found nothing obvious. Started up, all okay. Drove a mile or two and same thing. Pulled over waited about 30 seconds, restated and all okay. Fought it a few more times getting it home. Once it went into limp mode and only 30 mph. Where do I start? I don't have code reader. Would it show what's going on?
