I recently completed a 5.3, 4L60E swap in my 2003 Silverado RCSB 2wd, that was a 4.3 manual.
I used an 04 harness with drive by wire and it is running and driving great. It gets a thorough dyno tune tomorrow.
My issue is that the truck will start in every gear and the tow/haul button does not work. What am I suppose to do with the connector for the clutch position switch? Could this be my issue? Any info will be greatly appreciated!
