Move the gear selector switch to the N position.
When the N on the current gear indicator is solid
(not flashing), the TCU is ready to power down.

Selecting Gears
Neutral
IMPORTANT: Always start the engine with the
transmission in neutral (N), the parking brake
set, and the service brakes applied.
N is located directly below R on the four-position
gear selector switch on the SmartShift control lever.
To select N, move the gear selector switch to the po-
sition below R. When neutral is selected, the letter N
displays on the current gear indicator. See
Fig. 14.5.
WARNING
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 gear selector
switch is moved from N to D 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. To reset
the transmission, return the gear selector 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 gear se-
lector 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 gear selector switch.
Drive
Drive (D) is located directly below N on the four-
position gear selector switch on the SmartShift con-
trol lever. To select D, press in the neutral lock button
and move the gear selector switch to the position
below N. When D is selected, the number of the cur-
rently selected forward gear displays on the gear in-
dicator. See
Fig. 14.3.
When in drive, requests to upshift or downshift are
enabled. Either manual or automatic mode can be
selected on the slide switch.
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 control lever up or
down until the desired starting gear is displayed.
The 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. While
learning, it may hold a gear too long before upshift-
ing. Start the upshift manually. It may take three or
four shifts before UltraShift succeeds in learning the
new load-based shift points, but after that it will
handle the shifting automatically.
Reverse
Reverse (R) is located at the upper end of the four-
position gear selector switch on the SmartShift con-
trol lever. To select R, press in the neutral lock button
and move the gear selector switch upward to the po-
sition above neutral.
The UltraShift transmission has two reverse gears:
reverse low (RL) and reverse high (RH). To shift
manually between them, use the control lever as de-
scribed 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. See
Fig. 14.6.
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 gear selector switch is re-
turned to the D position or the vehicle slows to the
proper speed.
If necessary to rock the vehicle, use the gear selec-
tor switch to shift back and forth at low speed be-
tween reverse and drive.
