Manual Transmissions
NOTE: See Chapter 13 for complete manual
transmission operating instructions.
If so equipped, the transmission range control and
splitter valves are attached to the gear shift knob.
The range-preselection lever allows the selection of
the low or high range for each transmission ratio. It is
used once during an upshift sequence and once dur-
ing a downshift sequence.
Dependent on the transmission model, some ratios
can be split using the splitter-control button.
Eaton Automated Transmissions
NOTE: See Chapter 14 for complete automated
transmission operating instructions.
The SmartShift electronic transmission control is in-
stalled with the Eaton® Fuller® UltraShift
™
, UltraShift
PLUS, and AutoShift
™
transmissions. 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.
