Automated Transmissions
If the problem continues, contact an authorized
Freightliner or Eaton service facility.
Locked In Gear
If the transmission becomes locked in gear, a dash
(–) will appear on the current gear indicator when the
vehicle is restarted during the reset procedure.
NOTE: If the transmission becomes locked in
gear while the vehicle is moving, increased
braking effort may be required to stop the ve-
hicle.
If the current gear indicator displays a dash during
power-up with the selector switch in neutral, do the
following steps.
1. Make sure the parking brake is set.
2. Turn off the ignition and wait at least two min-
utes.
3. Apply the service brakes.
4. With the service brakes applied, release the
parking brake.
5. Make sure the selector switch is in neutral and
turn on the ignition key. Do not attempt to start
the engine at this time.
6. If necessary to get the transmission to shift into
neutral, release the pressure on the brake pedal
slightly.
7.
Once the UltraShift DM TCU reaches neutral, a
solid N will appear on the current gear indicator
and the vehicle will start. Make sure the service
brakes are applied and the parking brake is set.
If the current gear indicator continues to display a
dash, contact an authorized Freightliner or Eaton ser-
vice facility.

General Information, AutoShift
10-Speed RT/RTO Models
Eaton Fuller 10-speed AutoShift transmissions have
10 forward speeds and two reverse speeds. The
15.11
transmission consists of a 5-speed front section and
a 2-speed rear section. The driver must use the
clutch to start and stop the vehicle.
The driver does not need to break torque or increase
or decrease engine speed to synchronize the shift.
The transmission signals the engine controller when
to break torque and the engine controller automati-
cally increases or decreases engine speed. When
engine speed is correct, the transmission engages
the next gear and signals the engine controller to
resume operation.
WARNING
When starting or stopping on hills and grades,
use extra care to prevent the vehicle from rolling
back. A rollback accident could cause death, seri-
ous personal injury, or property damage.
The AutoShift system consists of the following com-
ponents:
•
The SmartShift control paddle on the steering
column. See Fig.
•
The gear display module
on the dashboard indicates the current gear
position or transmission status. The display
also flashes the next gear to be engaged while
the transmission is in neutral during a gear
change.
•
The shifter mechanism performs shifts at the
front portion of the transmission. It preselects
the shift to neutral and completes the gear
change after driver input.
•
The Electronic Control Unit (ECU) includes two
controllers: a transmission ECU and a system
ECU. The transmission ECU controls all trans-
mission shift functions and the system ECU
manages all vehicle interfaces for transmission
shift functions.
•
An electronic range valve, controlled by the
transmission ECU, is used to perform range
shifts.
Operation, AutoShift with SmartShift
Automatic and Manual Modes
A two-position slide switch (forward driving mode
switch) is located near the end of the control
(Fig. 15.6). The switch positions are labelled MAN
15.6.
