If the vehicle is approaching an overspeed condition, the transmission performs an
upshift at an engine speed of 2 500 rev/min to the next highest gear to decrease the
engine speed, whether in manual or automatic mode. If 6th gear is already selected,
the retarder is automatically engaged at 2600 rev/min to decrease the engine speed
irrespective of the accelerator position. The retarder is disengaged at 2450 rev/min.
A fault code will be displayed and recorded by the TCU. If the oil temperature reaches
150° C (302° F) the retarder is disengaged and a fault code will be displayed and
recorded by the TCU.
