DM is a ten-speed heavy-
duty fully automated transmission. No clutch pedal is
required to operate the vehicle.
UltraShift DM uses a dry clutch system which is of-
fered only on this automated transmission system.
The UltraShift transmission uses the four-position
SmartShift lever on the steering column to select
gears. To know what gear the transmission is in, look
at the round current gear indicator on the right-hand
control panel as shown in Fig. 8.22. All forward shifts
can be made either manually or automatically, at the
driver’s choice.
Operation, UltraShift DM
Power Up
1.
With the parking brake set, select neutral (N) by
moving the selector switch to the N position.
2.
With the transmission in neutral, turn on the igni-
tion switch. The "CHECK TRANS" and "TRANS
TEMP" telltale lights come on and go out again
(bulb check). See Fig. 8.23.
3.
After the ignition is turned on, the current gear
indicator shows the dot display, arranged in a
square pattern. All dots in the pattern should light
up, without gaps or spaces. See Fig. 8.24.
4.
Wait for the current gear indicator to show a solid
"N." When the "N" is solid, rather than flashing,
the UltraShift DM TCU is powered up. Apply the
service brake and start the engine.
5.
Select drive (D) by pressing in the neutral lock
button and moving the selector switch downward
to the position below neutral. Release the park-
ing brake. The gear is displayed on the current
gear indicator.
NOTE: When D is selected, the transmission
controller starts up in second gear. If desired,
the driver can select to start up in first. No other
start gear is available.
6.
On a level grade, release the service brake and
press down on the throttle pedal to allow the ve-
hicle to move forward. The vehicle will not move
until the pedal is depressed.
