Control
General Information, SmartShift
The SmartShift transmission control is an electronic
transmission control device. It is installed with the
following transmissions:
•
Eaton Fuller UltraShift
•
Eaton Fuller UltraShift
•
Eaton Fuller AutoShift
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
