After the fix the vehicle would stall and had a pulsating idle. Which we brought back to the dealer for repair. After a little research it was apparent...
  6. Commander 3.7l V6 - Gearbox 'clang' changing from 1st to 2nd

  10. '06 won't go into gear.

    General Commander Discussion
    Starts up fine but when shifting from park to anything else, nothing happens. Tried engaging 4WLow but even though the indicator light says its engaged, nothing moves. Cleared the CPU by detaching the neg battery terminal for 10+ minutes but still no joy. No leaks, unusual sounds... just won't...
