I had exactly the same issue. No codes and no CEL. Opening up the actuator motor and black gear is good. Replaced the transfer case drive chain, and problem fixed. When accelerated from stop, it jumped teeth due to stretched chain (dirty oil caused the chain to stretched). I spent less than $100 for part and dealer wanted $3,000.
