SAFETY RECALL INFORMATION:
(January 2019)
Mack Trucks has been informed by Eaton Corporation, plc (Eaton) that a defect which relates to motor vehicle safety may exist in certain automated manually shifted heavy duty vehicles equipped with an UltraShift PLUS, Fuller Advantage, or SmartAdvantage automated transmission model.
