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 ® AutoShift
•
Eaton Fuller UltraShift
•
ZF-FreedomLine
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.
Access to the sleeper is improved by removing the
shift lever from the floor.
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 is mounted on the body of
the control lever just before the paddle widens out.
The slide switch allows the driver to choose auto-
matic (AUTO) mode or manual (MAN) mode.
In AUTO mode, gears shift automatically, without
driver interaction. Manual gear shifts 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 the Eaton Fuller automated transmissions, a
four-position (R, N, D, L) selector switch
located at the end of the lever. For the FreedomLine
transmission, a three-position (R, N, D) selector
switch (Fig. 8.2) 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-

General Information, AutoShift
10-Speed RT/RTO Models
Eaton Fuller 10-speed AutoShift transmissions have
10 forward speeds and two reverse speeds. The
transmission consists of a 5-speed front section and
a 2-speed rear section. The driver must use the
clutch to start and stop the vehicle.
The driver does not need to break torque or increase
or decrease engine speed to synchronize the shift.
The transmission signals the engine controller when
