With the transmission in drive, to request an upshift,
pull the control lever up (towards you). If the gear is
available, the transmission will upshift.
An unavailable request to upshift is not stored in
memory. The upshift must be requested again. Skip
shifting in manual mode is not available with the ZF
Meritor version of SmartShift.
Downshifting
NOTE: A request to upshift or downshift can
only be accepted in the manual mode.
With the transmission in drive, to request a down-
shift, push the control lever down (away from you). If
the gear is available, the transmission will downshift.
An unavailable request to downshift is not stored in
memory. The downshift must be requested again.
Skip shifting in manual mode is not available with the
ZF Meritor version of SmartShift.
IMPORTANT: A downshift request can never
result in a shift into neutral, even if the vehicle is
in the drive position in the lowest possible gear.
Selecting a Non-Default Starting Gear
NOTE: For the clutch to engage, pressure in the
primary air system must be at least 100 psi (689
kPa).
1.
Select drive (D) by pressing in the safety release
and moving the selector switch downward to the
position below neutral.
2.
Select manual mode (MAN) by moving the two-
position slide switch towards the steering column
until it is in the manual position.
3.
To increase the starting gear, pull the lever up
(towards you). To decrease the starting gear,
push the lever down (away from you).
4.
Select automatic mode (AUTO), if desired, by
moving the two-position slide switch away from
the steering column until it is in the automatic po-
sition.
Driver Message Center
On the Century Class S/T, the gear is displayed on
the driver display screen in the SmartDash
™
(ICU2M)
message center. See
Fig. 8.14
.
The first character of the display is either blank, to
indicate the transmission is in manual mode, or an
up-and-down arrow to indicate the transmission is in
automatic mode.
NOTE: Pre-production vehicles will have a small
numeric "10" in place of the up-and-down arrow
when in automatic mode.
The next two characters indicate the current gear.
For forward drive gears, this appears as a two-digit
number (
Examples
: "03, "11"). For reverse, two let-
ters appear, either "RL" for low reverse (the default),
or "RH" for high reverse. For neutral, a single letter
"N" appears.

General Information, Eaton Range-
Shift
To operate a range-shift transmission, move the shift
lever through all of the low gear positions, then acti-
vate the range switch. This provides an additional set
of ratios in the high range. Using the same shift lever
positions as used in low range, move the shift lever
through each position as before. On some models,
the initial low gear is used only in low range.
Eaton Fuller Range-Shift transmissions are not syn-
chronized in the front section, but the range section
is synchronized to prevent grinding gears during
range shifts.
IMPORTANT: Not all lever positions are used in
each range and the shift patterns vary between
