STARTING AND DRIVING
ALLISON TRANSMISSION
WARNING
To help avoid unexpected vehicle
movement that might cause death,
serious injury, or property damage, always
have your foot on the brake, the throttle
released, and the engine at idle before
making a N (Neutral) to D (Drive)
;
N
(Neutral) to R (Reverse)
;
D (Drive) to R
(Reverse)
;
or R (Reverse) to D (Drive)
selection.
NOTE
Conditions responsible for illuminating the
CHECK TRANS indicator will not allow
any shift selector changes until the DTC
related to the condition goes inactive. The
MONITOR display shows the range the
transmission has locked in because of an
active DTC. The SELECT display goes
blank when the CHECK TRANS indicator
is on. Move the vehicle to a safe location
before turning off the vehicle and seek
qualified assistance if needed. Even if the
transmission is not in N (Neutral), the
operator will be able to view DTCs by
simultaneously pressing the
↑
(Upshift)
and
↓
(Downshift) arrows, if equipped with
the keypad pushbutton shift selector, or
by pressing the DISPLAY MODE/
DIAGNOSTIC (DMD) button, if equipped
with the bumpshift lever selector.
With an Allison Transmission, the shift
selector is used by the operator to select
N (Neutral), R (Reverse), or a range of
forward gears. When a forward range
has been selected, the transmission
starts in the lowest gear of the range
and, as conditions permit, automatically
upshifts to the highest gear in the
selected range.
Shifter Gears
• R – REVERSE: selects Reverse gear.
• N – NEUTRAL: selects Neutral. The
area around the N button is a raised
ridge so the driver can identify the
pushbuttons by touch, without
looking at the display. It is not
necessary to press this button prior
to starting the vehicle.
• D – DRIVE: selects the highest
available forward range. The
transmission shifts to the starting
gear and will automatically upshift
through the gears, as operating
conditions permit, until the highest
available gear is attained.
Upshifting and Downshifting
The (Upshift) and (Downshift) arrows are
used to change the range selected to a
higher or lower forward range:
• One press of the (Downshift) arrow
sets range SELECT to the same
forward range as the current forward
range attained shown in the
MONITOR position on the display.
This type of preselect is called an
Express Preselect.
• Each subsequent press of the
↓
(Downshift) arrow decreases the
range selected by one range.
• One press of the (Upshift) arrow
increases the range selected by one
range.
• If the (Upshift) or (Downshift) arrow is
held continuously, the selected range
will continue to change up or down
until the button is released or until
the highest or lowest possible range
of gears is selected.
Shift Schedules
Each transmission shift calibration
includes multiple shift schedules which
are used to control transmission shifts in
various operating conditions. The shift
schedules affect the timing of shifts
between gears. The actual number of
forward gears is determined based on
the transmission model and the selected
range position of the shift selector.
Vehicle performance may be affected
when shift schedules change. The
transition between shift schedules can
be initiated by several different actions.
The transmission initially attains first
range when D (Drive) is selected (except
for those units programmed to start in
2nd range). As vehicle speed increases,
