Freightliner SmartShift Shift
Control
General Information, SmartShift
The SmartShift transmission control is an electronic
transmission control device. It is installed with the
following transmissions:
•

Eaton Fuller UltraShift

•
Mercedes-Benz Automated Gear Shift (AGS)
It replaces the typical floor-mounted shift lever or
dash-mounted push button control.
SmartShift accepts driver requests for transmission
functions and transmits them through hard wiring to
the transmission control unit (TCU). SmartShift is a
true shift-by-wire system.
SmartShift offers two main advantages over conven-
tional transmission control devices. Without a floor-
mounted shift control, usable cab space is increased.
The SmartShift control mounts to the right-hand side
of the steering column and is operated by the fingers
of the driver's right hand, allowing both hands to re-
main on the steering wheel.
A two-position slide switch
the body of the control lever just before the paddle
widens out. The slide switch allows the driver to
choose automatic (AUTO) or manual (MAN) mode.
In AUTO mode, gears shift automatically, without
driver interaction. Manual gearshifts are accom-
plished by a momentary pull or push on the control in
the plane perpendicular to the steering wheel. Pull
upward (toward you) on the control to upshift and
push downward (away from you) to downshift. The
control is spring-loaded and returns to mid-position
when released after an upshift or downshift.
For Eaton Fuller UltraShift
(R, N, D, L) selector switch is located at the end of
the lever. For the Mercedes-Benz AGS
three-position (R, N, D) selector switch is located at
the end of the lever.
Embedded in the selector switch is a small neutral
lock button to prevent accidental shifts into gear from
neutral. Any time you shift through N, press down on
the neutral lock button to move the switch from neu-
tral (N) to another gear, such as drive (D), low (L), or
reverse (R). When shifting to N, it is not necessary to
press the neutral lock button.

column to change gears, combined with a gear indi-
cator on the right-hand control panel as shown in

manually or automatically, at the driver's choice. No
clutch pedal is required to operate the vehicle.
General Information, UltraShift ASW
UltraShift ASW is a six-speed medium-duty fully au-
tomated transmission used on the M106 only. Six-
speed UltraShift ASW uses a "wet" clutch system in
which the drive and driven discs rotate in a bath of
transmission fluid (Dexron III).
General Information, UltraShift DM
UltraShift DM is a ten-speed heavy-duty fully-
automated transmission used on the M112 only. Ten-
speed UltraShift DM uses a dry clutch system which
