Warnings
Set the parking brakes before starting a vehicle, always be seated in the
driver’s seat, move the shift level to neutral, and depress the master clutch.
If engine cranks in any gear other than neutral or without the master clutch
depressed, service your vehicle neutral safety start circuit immediately.
Before working on a vehicle or when leaving the cab with the engine running,
place the transmission in neutral and set the parking brakes.
Do not release the parking brake or attempt to select a gear until the air pres-
sure is at the correct level.
When parking the vehicle or leaving the cab, always place the shift lever in
neutral and set the parking brakes.
If your vehicle is equipped with a remote throttle, before operation, the trans-
mission must be in neutral.

General Information
General Information
Models in this series provide thirteen forward speeds and two reverse, con-
sisting of a five-speed front section and a 3-speed auxiliary section. The auxil-
iary section contains LO and HI range ratios, plus the L and H splitter gear
ratios.
The LO position in the front section is used only as a starting gear. The other
four ratios are used once in LO range and once again in HI range. Each of the
four ratios, when used in HI range, can be split with the splitter control button.
After shifting out of the LO position, use the Roadranger repeat “H” shift pat-
tern. LO range and HI range are selected with the range lever. It is used once
during the upshift and once during the downshift sequence.
Always preselect the range shift. After preselection, the transmission will
automatically make the synchronizer range shift as the shift lever passes
through neutral.
When in HI range, the gear ratios can be split by using the Splitter Control
Button. The “L”/Rearward position gives the 5th, 6th, 7th, and 8th speed
ratios; the “H”/Forward position splits each of the HI range speed ratios.
Therefore, eight progressive HI range ratios can be obtained.

Features

Range Shift
Preselect
Note: Always preselect all range and splitter shifts when upshifting or down-
shifting. Preselection requires that the range lever and/or splitter button
are moved to the needed position before starting the shift.
Preselected range shifts are completed automatically as the lever is moved
through neutral and into the next gear. Preselecting all range shifts prevents
damage to the transmission and provides for smoother shifts.
Preselected splitter shifts allow smooth and faster shifts. However, do not
delay, start and complete the shift immediately after preselecting the splitter to
avoid unnecessary wear on internal transmission parts.
Splitter Shift
The splitter control button selects LO split “L” or HI split “H”. It is used in each
HI range speed ratio.

Features
Optional Equipment
For easier and faster gear engagement while the vehicle is standing still, some
Eaton Fuller transmissions may be equipped with either a Countershaft Brake
or a Clutch Brake.
Countershaft Brake
(Used with push-type clutches) - The control button is mounted on the shift
lever just below the shift knob. To operate, disengage the clutch, press down
the control button, and shift into LO or reverse. This is an air-operated
mechanical brake which slows down the transmission gearing by forcing a
piston against the countershaft PTO gear.
Clutch Brake
(Used with pull-type clutches) -The clutch brake is applied by fully depressing
the clutch pedal to the floor board. When applied, the brake slows down and
can stop the transmission front box gearing. It is a disc-type brake incorpo-
rated into the clutch and transmission drive gear assemblies.

Operation
Double-Clutching Procedure
4. Quickly depress pedal to disengage clutch and move gear shift lever
to next gear speed position.
5. Release pedal to engage clutch.
*By engaging the clutch with the gear shift lever in the neutral position, the
operator is able to control the RPM of the mainshaft gears since they are reg-
ulated by engine RPM. This procedure enables the operator to match the RPM
of the mainshaft gears with those of the mainshaft driven by the vehicle’s rear
wheels.
9
Operation
Initial Start-up
1. Make sure the shift lever is in neutral and the parking brakes are set.
2. Turn on the key switch, start the engine.
3. Allow the vehicle air pressure to build to the correct level. Refer to
your “Operator and Service Manual” supplied with the truck.
4. Apply the service brakes on the vehicle.
5. Release the parking brakes on the vehicle.
6. Make sure the range lever is down in the LO range position and the
splitter control button is rearward.

Operation
Shifting
In the following instructions, it is assumed that the driver is familiar with oper-
ating heavy duty-trucks and tractors, and can coordinate the movement of the
shift lever and clutch pedal to make smooth gear engagements while upshift-
ing and downshifting. Always double-clutch when making lever shifts.
CAUTION: Never move the range lever or the splitter control button
with the shift lever in neutral while the vehicle is moving.
Upshifting
1. Move the shift lever, double-clutching, to the next desired gear posi-
tion in LO range.
Range Shift - LO to HI Range “L” (4th to 5th L)...
2. When in last gear position for LO range and ready for the next
upshift, pull up the range lever and move the shift lever, double-
clutching, to the next higher speed position according to your shift
pattern. As the shift lever passes through neutral the transmission
will automatically shift from LO to HI range.
CAUTION: Never move the shift lever to the LO gear position after
HI range preselection, or at any time the transmission is in HI
range.
11
Operation
Combination Lever shift and Splitter Shift - HI Range “H” to HI Range “L”
(5th H to 6th L)...
CAUTION: Never move the splitter control button or the range lever
with the shift lever in neutral while the vehicle is moving.
Downshifting
12
Operation
6. While in HI range “L” and ready for the next downshift, preselect LO
range, push the range lever down.
13
Lubrication
Proper Lubrication
CAUTION: Never mix engine oils & gear oils in the same trans-
mission.
14
Lubrication
Make sure the transmission lubricant is level with the bottom of the fill open-
ing. Being able to reach the lubricant with your finger does not mean the lubri-
cant is at the proper level. (On heavy duty transmissions, one inch of lubricant
level equals about one gallon of lubricant.)
Note: The first lube change for a Line-Haul vehicle may be extended to
500,000 miles (800,000 km) when a new transmission has been factory
filled with a lube that is Eaton approved for 500,000 miles (800,000 km)
(E-500, PS-164).
Note: Vocational service applications are those which require components to
be consistently operated at heavy loads, in contaminated environments
or on steep grades. For these applications, the Vocational Service sec-
tion should be used.

Draining Oil
Drain transmission while oil is warm. To drain oil, remove the two (2) drain
plugs at the case bottom and oil pan. Clean the drain plugs and flush the
cooler circuit before re-installing.
Refilling
The operational level should always be within the appropriate temperature
bands on the dipstick. The exact amount of oil depends on the transmission
inclination and model. Insufficient oil damages the pump and other compo-
nents, and can affect the function and reduce the life of the transmission.
When adding oil, types and brands of oil should not be mixed because of pos-
sible incompatibility.
Use clean oil and clean containers when filling transmission. Containers that
have been used for anti-freeze or water should not be used for transmission
oil.
1. Remove the dipstick and slowly add of the prescribed oil through the
fill tube.
2. Place the transmission in neutral position and apply the parking
brakes. Start the engine and let it idle for five (5) minutes, (this
allows oil to fill the converter, main case, and cooling system). Add
oil as needed to obtain a level at the proper temperature range. Total
oil quantity varies depending on the cooling system.
3. Increase the engine idle slowly to 1500 RPM for five (5) minutes.
Now recheck the oil level at normal idle speed in neutral, again add-
ing oil to obtain a level at the proper temperature range.
4. Replace the dipstick and tighten securely.

Upshift Procedure
Downshift Procedure
1. To downshift from top gear: Once the engine has reached the shift
point the transmission will automatically downshift.
2. To downshift from “AUTO” position to 7th H:
b. Once the engine has reached the shift point move the lever to
the next lower lever position while double-clutching.
21
Appendix
Driving Tips
To activate Top 2 mode, the transmission must be shifted from 7th H to AUTO
once the engine has reached the normal shift point. If the operator moves the
shift lever into the AUTO lever position below the engine’s normal shift point,
the transmissions will be in normal Super 13 mode. Once the engine reaches
the normal shift point, Top 2 mode will become active.
Throttle position determines the upshift point. Less throttle will lower the shift
point. Zero throttle (down hill push) will raise the upshift point. To reset the
shift points the engine must drop below its normal shift point.
With the engine brake active, the up and down shift points will be raised.
22
Appendix

23
Appendix
System Problem
In some situations, the system can be reset at a stop by leaving the key off for
10 seconds and then restarting the engine. If this does not clear the problem,
verify air pressure and check the electrical connections to the Top 2. To help
assure operation of the Super 13 Top 2, advise your maintenance personnel of
any oil leaks, above normal operating temperatures, unusual noises, fault
codes, or if the transmission is not operating right.
These instructions assume the driver is currently familiar with the operation of
a normal Super 13 transmission.
