Eaton Automated
Transmissions
Eaton automated transmissions use shift selection
software and electric clutch actuation; a clutch pedal
is not needed to operate the vehicle. These transmis-
sions use the multi-function stalk switch shown in
Fig. 17.1 to select mode, direction, neutral, low, and
to make manual shifts. To know what gear the trans-
mission is in, see the driver display. Forward shifts
can be made either manually or automatically.
Automatic Mode (A)
In automatic drive mode, upshifts and downshifts are
made by the transmission without driver intervention.
Use the mode switch on the shift control to select the
automatic mode (A). Rotate the D/N/R switch to
Drive (D), and press down on the throttle pedal. The
transmission will shift automatically.
NOTE: If attempting to select a non-Neutral
mode without applying the service brakes, the
transmission will not shift into gear. To shift into
gear, select Neutral, apply the service brakes,
and select the desired mode again.
In Drive, the start gear is automatically selected. The
selected start gear can vary depending on several
vehicle inputs such as load, grade, and axle/
transmission ratio. The start gear can be changed
using the shift control, provided the selected gear
would allow the vehicle to launch without damaging
the transmission. If the start gear is changed using
