Warnings & Cautions
Warnings & Cautions
WARNING
Read the entire driver instructions before operating this transmission.
Before starting a vehicle always be seated in the driver's seat, select “N”
on the shift control, and set the parking brakes.
If engine cranks in any gear other than neutral, service your vehicle immediately!
Before working on a vehicle, parking the vehicle, or leaving the cab with
the engine running, place the transmission in neutral, set the parking
brakes, and block the wheels.
For safety reasons, always engage the service brakes prior to selecting
gear positions from "N".
CAUTION
Do not release the parking brake or attempt to select a gear until the air
pressure is at the correct level.
Before operating the PTO, refer to “Transmission Power Take Off Operation”.
Battery (+) and (-) must be disconnected prior to any type of welding on any
UltraShift™ equipped vehicle.
IMPORTANT
It is a requirement that the driver of a commercial vehicle specified under
paragraph A sections 1-6 of FMCSA regulation 392.10 need only cross railroad grade crossings in a gear that permits the vehicle to complete the
crossing without a change of gears.
This can only be achieved by utilizing the Manual “M” mode. Please refer
to pages 2 and 9 for correct manual mode operation.

TRANSMISSIONS
R Selects Reverse gear once vehicle speed is less than 2 mph.
N Selects Neutral
D Selects the default starting gear and automatically selects
gears between the starting gear and top gear.
MANUAL Allows the driver to hold current gear and manually select the
appropriate gear for road conditions using the up/down buttons. MANUAL mode should be used whenever the driver
wants to select the shifts instead of letting UltraShift select
them automatically. For example, when the driver is moving
around the yard, over railroad tracks, or on steep grades.
(See the “Manual Mode” section for more details.)

PTO Power Take Off is activated and transmission is ready for PTO

section for more details.)
WARNING
UltraShift™ initiates upshifts from “MANUAL” and “LOW” for engine over
speed protection. Some engines do not use the Eaton engine overspeed
protection.

Operation
Start-up and Power Down
Start-up
1. Turn the ignition key to “ON” and allow the UltraShift to power-up.
• Engine cranking is delayed until the transmission power-up is
complete and the gear display shows a solid “N”.
2. Start the engine.
3. Apply service brake.
• If the service brake is not applied while selecting a starting gear,
the initial start gear will not be found and the driver will have to
re-select Neutral and press the brake while re-selecting the
desired mode.
4. Select the desired mode and starting gear, on the shift console.
5. Release the vehicle parking brakes.
6. Release service brake and apply accelerator.
• The transmission is not intended to provide hill-hold capability.
The service brakes should be used to stop and hold the vehicle
on an incline. To prevent the vehicle from rolling when starting
on an incline, place both feet on the brake pedal before sliding
the right foot to the throttle pedal. Gradually back off the brake
while applying as little throttle as necessary to move along the
incline.
Power Down
1. Select Neutral on the shift control.
• If gear display does not show solid “N”, neutral has not yet been
obtained.
Note: Neutral should always be reached before UltraShift power down is per-
formed except in cases of emergency.
2. Set the vehicle parking brakes.
3. Turn off the ignition key and allow the engine to shut down.

Operation
Driving Tips
Proper Starting Gear
Choose a starting gear appropriate for the load and grade conditions, while at
a stop in Drive and MANUAL modes by using the up/down buttons. Refer to
Drive Mode for detailed information.
Skip Shifting
Performed in MANUAL by pressing the shift arrows more than once. Refer to
MANUAL mode section for detailed information. Automatic Skip Shifts may
occur in Drive Mode if conditions are appropriate.
Optimal Engine Braking
The LOW mode can be selected while moving. This initiates downshifts as
soon as possible to maximize the effect of engine braking. Refer to Low mode
section for detailed information.
Skid Conditions
If a skid condition occurs, the UltraShift senses the vehicle speed dropping
rapidly. In this case, the UltraShift delays downshifting and will automatically
disengage the master clutch if necessary.
Cruise Control
The UltraShift is totally compatible with cruise control. If a shift is required
while cruise control is active, cruise is temporarily interrupted while the shift
is performed and then automatically resumed after the shift.
Manual Mode
In Manual Mode UltraShift Allows the driver to hold current gear and manually
select the appropriate gear for road conditions using the up/down buttons.
Manual mode should be used whenever the driver wants to select the shifts
instead of letting UltraShift select them automatically. Examples include, when
the driver is moving around the yard, over railroad tracks, or on steep grades.
