Caution : Before ascending or descending a long
or steep grade, reduce speed and shift into a
lower gear. Use lower gears to control speed and
avoid prolonged or frequent braking which will
result in brake overheating and reduce braking
effectiveness. To reduce brake wear, use the
JACOBS engine brake when descending a steep
grade.
Warning

slippery surfaces should be done with caution.
Sudden engine compression braking could cause
drive wheels to lock-up, and may result in loss of
control.

AUTOMATIC TRANSMISSION

The operation and driving of this vehicle with an
automatic transmission is similar to that of an
automobile equipped
transmission. Proper ranges should be selected
according to driving speeds to improve vehicle
performance and control. The transmission is fully
automatic. Speed ratio of power converter
changes automatically as vehicle speed increases
and direct-drive goes in and out as necessary,
modulated by vehicle speed, and accelerator
position.
Range Selection - Push-Button Shifter
The push-button shifter is used by the operator
to select Neutral (N), Reverse gear (R), or a
range of forward gears. When a forward gear
range has been selected, the transmission starts
in the lowest gear of the range and, as
conditions permit, automatically upshifts until the
highest gear in the selected range is in use.
The digital display indicates the current gear of
transmission operation.
