WARNING
Do not allow the vehicle to coast in Neutral. This
practice can result in severe transmission damage.
The transmission upshifts and downshifts
automatically between first range and the highest range
selected on the range selector in direct response to
throttle position and transmission output speed.
When Reverse is selected the reverse alarm sounds
and the reverse light illuminates at the rear of the
vehicle. This feature warns personnel to the immediate
rear of the vehicle that the operator has shifted
to reverse.
When drive 'D' is selected, the transmission
automatically upshifts and downshifts through all six
forward ranges as required by loads and travel speeds.
Selecting a lower range (4th, 3rd etc.) limits the highest
range to which the transmission will automatically upshift.
If a lower range is selected while moving forward, the
transmission automatically downshifts sequential to

the selected lower range at maximum controlled engine
speeds. Downshifts will not occur until vehicle is
slowed by use of the service brakes and/or retarder.
When shifting from neutral to start from a standstill,
or to reverse direction, decelerate the engine to idle
speed. To move forward, select drive 'D' and accelerate
the engine to the vehicle load and speed requirements.
The transmission will automatically upshift from 1st
through 6th ranges as travel speed increases.
With the throttle fully depressed, and the mode
selection switch in the Power position, the
transmission upshifts to the next higher range when the
engine attains maximum rated speed, since maximum
power train output is needed under this condition.
At lower throttle settings where minimum power train
performance is required, the transmission will upshift
to the next higher range at less than maximum
rated engine speed.
Upgrades or soft spots might slow travel speed, even
at full throttle, requiring transmission downshifts to
maintain maximum powertrain performance. When this
occurs, the transmission downshifts automatically.
