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.

EATON FULLER 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.)

MANUAL

LOW

LOW Transmission downshifts at the earliest opportunity for maxi-

mum engine braking.

Up / Down

Used in the MANUAL mode to select upshifts and downshifts.

Buttons

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

operation. (See “Transmission Countershaft Power Take Off” 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

Gear Display

The Gear Display shows the current gear position of the transmission. The Gear Display will flash the target gear position of the transmission when in neutral during a shift.

FLASHING

Down arrows on the Gear Display indicate the transmission is waiting to verify decreased input shaft speed, before a gear engagement from Neutral can be completed.

The “DASH” indicates the transmission may be torque locked in gear (see Service and Maintenance Locked in Gear).

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.
