General Information, SmartShift Control

108SD d 14.02.000

The SmartShift electronic transmission control is installed with the following transmissions:

  • Eaton Fuller UltraShift PLUS

  • 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 conventional transmission control devices. Without a floor-mounted shift control, usable cab space is increased. The SmartShift control is operated by the fingers of the driver's right hand, allowing both hands to remain on the steering wheel.

A two-position driving mode 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 automatic (AUTO) or manual (MAN) mode. See Fig..

In AUTO mode, gears shift automatically without driver interaction. Manual gearshifts are accomplished by a momentary pull or push on the control in the plane perpendicular to the steering wheel. Pull upward (toward the driver) on the control to upshift and push downward (away from the driver) to downshift. The control is spring-loaded and returns to its rest position when released after an upshift or downshift.

A four-position (R, N, D, L) gear selector switch is located at the end of the lever. See Fig..

A small neutral lock button is embedded in the gear selector switch to prevent accidental shifts into gear from neutral. Any time you shift through neutral, press down on the neutral lock button to move the switch from neutral (N) to another gear, such as drive (D), low (L), or reverse (R). When shifting to neutral, it is not necessary to press the neutral lock button.

To upshift manually, pull the lever back (towards the driver). To downshift manually, push the lever forward (away from the driver).
