In addition to the Maintenance Minder service, GM recommends replacement of the Air Filter, Spark Plugs, Transfer Case Fluid and the Automatic Transmission Fluid/Filter. You can get this estimate if you look under "Scheduled Maintenance" in the RepairPrice Estimator. http://repairpal.com/estimator?car_type_id=4951 and select the Maintenance I or II service.
