Drivetrain
Ten-speed UltraShift DM has two reverse gears, re-
verse low and reverse high. To shift manually be-
tween them, use the shift lever as described for MAN
mode. There is no AUTO mode for reverse.
When reverse low is selected, the letter "R" displays
on the current gear indicator. When reverse high is
selected, the letter "H" displays on the current gear
indicator.
IMPORTANT: Under normal conditions, do not
select reverse with the vehicle moving forward.
The vehicle must be moving at less than two miles
per hour (3 km/h) before selecting reverse. If reverse
is selected when the vehicle is moving faster, an au-
dible alert will sound and continue sounding at three-
second intervals until the control lever is returned to
the D position. When the vehicle is moving at the
proper speed, reverse can be engaged.
On ten-speed UltraShift DM only, if necessary to rock
the vehicle, use the selector switch to shift back and
forth at low speed between reverse and drive.
Neutral
IMPORTANT: Always start the engine with the
transmission in neutral, the parking brake set,
and the service brakes applied.
Neutral (N) is directly below R on the four-position
selector switch located at the end of the SmartShift
control lever. To select N, move the selector switch to
the position below R. When neutral is selected, the
letter "N" displays on the gear indicator. See
Fig. 8.18.

Do not coast in neutral. Coasting in neutral can
cause an accident, possibly resulting in severe
personal injury or death.
Neutral is always available during operation, what-
ever the vehicle speed. When in neutral, requests to
upshift or downshift are ignored. If the selector switch
is moved from neutral to drive while the vehicle is
moving, the transmission will shift into a gear within
the engine's operating speed range.
When shifting from neutral, always press on the
brake pedal. If the brake pedal is not pressed, the
transmission will not shift, the current gear display
will flash "N," and an audible alert will sound.
NOTE: To reset the transmission, return the se-
lector switch on the SmartShift lever to N and
attempt the shift again, this time with the brake
pedal pressed.
Before shutting down the engine, return the selector
switch to "N." When the ignition is turned off, the
transmission will reset to neutral in a few minutes
regardless of the position of the shift lever.
Drive
Drive (D) is directly below N on the four-position se-
lector switch located at the end of the SmartShift
control lever. To select D, press in the neutral lock
button and move the selector switch to the position
below N. When drive is selected, the number of the
currently selected forward gear (1 through 6 on six-
speed UltraShift ASW; 1 through 10 on ten-speed
UltraShift DM) displays on the gear indicator. See
Fig. 8.16.
When in drive, requests to upshift or downshift are
enabled. Either manual or automatic mode can be
selected on the slide switch.
Two starting gears are available, first and second.
The default starting gear is second, but first can be
selected by the driver, if desired. To change the start-
ing gear, press the brake pedal and select D with the
vehicle stopped. The current gear indicator will dis-
play the starting gear. Move the shift lever up or
down until the desired starting gear is displayed.
The UltraShift TCU adapts to the working conditions

of each vehicle and its driver. After power-up or a
load change, it needs to learn the new conditions.
