I have a 4L80E behind my 6.0 in my 85 K10. I'm having trouble getting the pcm and vss to read each other properly, I'm starting to think I need and updated version of editor to changes the pulses per rev transmission and vss pulse in general, properly as this unit sends 8000k per mile and I believe the stock vss sent 40 something? Any help for a newbie would be extremely appreciated!!!!
