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
•
™
Meritor SureShift
•
™
ZF Meritor 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. Usable cab
space is increased and access to the sleeper is im-
proved 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. The
SureShift lever has no slide switch.
In AUTO mode, gears shift automatically, without
driver interaction. Manual gear shifts (all SureShift
shifts; AutoShift, UltraShift, or FreedomLine when in
MAN mode) are accomplished 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 Meritor Sure-
Shift transmission, a three-position (R, N, F) selector
switch (Fig. 8.2) is located at the end of the lever.
For the Meritor FreedomLine transmission, a three-

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.
