Spartan Motors USA (Spartan) is recalling certain model year 2014-2016 Legend and Star fire trucks manufactured April 15, 2015, to April 16, 2016. The affected vehicles may be equipped with certain C20 and C21 split-shaft transmissions from Waterous. This transmission sends power to the wheels of an emergency response vehicle or powers an add-on unit such as a water pump used for fighting fires. A component within the shift unit may be damaged and as a result, the operator may not be able to switch the power output.
