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 torque range.
Before shutting down the engine, return the selector
switch to N. When the ignition is turned off, the trans-
mission will reset to neutral in a few minutes regard-
less 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 10) dis-
plays on the gear indicator. See Fig. 8.10.
When in drive, requests to upshift or downshift are
enabled. Either manual or automatic mode can be
selected on the slide switch.
More than one starting gear is available. To change
the starting gear, press the brake pedal and select D
with the vehicle stopped. The current gear indicator
will display the starting gear. Move the shift lever up
or down until the desired starting gear is displayed.
The UltraShift DM TCU adapts to the working condi-
tions 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
upshifting. 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.
Low
Low (L) is located at the lower end of the four-
position selector switch located at the end of the
SmartShift control lever. To select L, press in the
neutral lock button and move the selector switch to
the position below D.
When in low, the current gear is maintained. Re-
quests to upshift are not enabled.
IMPORTANT: If the engine is approaching over-
speed, the UltraShift DM TCU will override the
current gear setting and upshift to prevent en-
gine damage.
To enhance engine braking, downshifts are per-
formed at higher rpm than normal.
If L is selected from neutral while stopped, the ve-
hicle starts up in first gear and stays there until the
engine approaches overspeed.
Upshifting
To request an upshift with the transmission in drive,
pull the control lever up (towards you). If the gear is
available, the transmission upshifts and the new gear
displays on the gear indicator. No skip shifts are
available while upshifting.
No upshifts are available in low, except to prevent
engine overspeed.
If the transmission does not upshift quickly enough
after power-up or a load change, begin the shift
manually. The UltraShift DM TCU will learn the new
load-based shift conditions after three or four shifts.
If the gear requested is unavailable, a tone will
sound. An unavailable request to upshift is not stored
in memory. The upshift must be requested again.
Downshifting
NOTE: The driver can manually downshift at
any time, even when the slide switch is set to
AUTO mode.
To request a downshift with the transmission in drive
or low, push the control lever down (away from you).
If the gear is available, the transmission downshifts
and the new gear displays on the gear indicator. Skip
shifts are available while downshifting.
