Precautions
Cautions & Warnings
Read the entire driver instructions before operating this transmission.
Before starting a vehicle always be seated in the driver's seat, move the shift lever to
neutral, and set the parking brakes.
Before working on a vehicle or when leaving the cab with the engine running, place the
transmission in neutral, set the parking brakes, AND block the wheels.
When parking the vehicle or leaving the cab, always place the shift lever in neutral and
set the parking brakes.
When towing the vehicle, the output shaft of the transmission must not be allowed to
spin or turn. If the vehicle is towed with the drive wheels still in contact with the road
surface, the vehicle axle shafts or driveline must be removed or disconnected.
WARNING: Serious internal transmission damage can result from
improper vehicle towing.

General Information
Overview
A shift pattern diagram should be in your vehicle. If it has been lost, a replace-
ment may be obtained by writing to: Eaton Corporation, Transmission Divi-
sion, Service Parts Department, North American Headquarters, P.O. Box 4013,
Kalamazoo, Michigan 49003-4013. Please give the transmission model num-
ber when making request.
The 7-speed transmissions have seven forward speeds and one reverse. All
models are shifted as you would shift any manual transmission, following the
simple 7-speed shift pattern. Coordinate the necessary movements of the shift
lever and clutch pedal to make each gear engagement. Always double-clutch
when making lever shifts (See “Double-Clutching Procedure” Section).
The longer lever throw in 6th and 7th gear positions provide greater clutching
gear tooth contact.
Skip-Shifting
After becoming proficient in shifting, you may want to skip some of the ratios.
This may be done ONLY when operating conditions permit, depending on the
load, terrain and road speed.
Optional Equipment - The Clutch Brake
For easier and faster gear engagement, some Fuller
transmissions may be equipped with a Clutch Brake.
This brake is used to make initial gear engagement into
1st or reverse while the vehicle is standing still.
The brake is applied by fully depressing the clutch pedal
to the floor board. When applied, the brake slows down
the transmission gearing. It is a disc-type brake incor-
porated into the clutch and transmission drive gear assemblies.
Note: Never use the Clutch Brake when down-shifting, or as a brake to slow
the vehicle.

General Information
Driving Tips
• For a smooth start, always select an initial starting gear that will pro-
vide sufficient reduction for the load and terrain.
• Always use normal double-clutching procedures when making lever
shifts. (See “Double-Clutching Procedure” Section).
• Never slam or jerk the shift lever to complete gear engagement.
• Never coast with the gear shift in the neutral position.
• Never downshift at too high of a road speed.
• In most cases, depending on the engine and the axle ratios, you can
save valuable fuel by operating the engine at less than governed
RPM while cruising in 7th.
Double-Clutching Procedure
When ready to make a shift:
1. Depress pedal to disengage clutch.
2. Move gear shift lever to neutral.
3. Release pedal to engage clutch.*
a. Upshifts - decelerate engine until engine RPM and road speed
match.
b. Downshifts - accelerate engine until engine RPM and road speed
match.
4. Quickly depress pedal to disengage clutch and move gear shift lever
to next gear speed position.

General Information
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.

Lubrication
Proper Lubrication
Proper lubrication procedures are key to a good all-around maintenance pro-
gram. If the lubricant is not doing its job or if the lubricant level is ignored, all
the maintenance procedures in the world are not going to keep the transmis-
sion running or assure long transmission life.
Eaton® Fuller® Transmissions are designed so the internal parts operate in
an oil bath circulated by the motion of the gears and shafts.
Thus, all parts are amply lubricated if these procedures are closely followed:
1. Maintain lubricant level and inspect regularly.
2. Follow maintenance interval chart.
3. Use the correct grade and type of lubricant.
4. Buy lubricant from an approved dealer.
Mixing of Oil Types
CAUTION: Never mix engine oils & gear oils in the same transmission.
Engine oils and gear oils may not be compatible; mixing can cause breakdown
of the lubricant and affect component performance. When switching between
types of lubricants, all areas of each affected component must be thoroughly
flushed.
Note: For a list of Eaton Approved Synthetic Lubricants, see TCMT-0021 or
call 1-800-826-HELP (4357).
Note: Additives and friction modifiers must not be introduced.

Lubrication
Proper Transmission Lubrication Level
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.)
If the transmission operating angle is more than 12 degrees, improper lubrica-
tion can occur. The operating angle is the transmission mounting angle in the
chassis plus the grade (expressed in degrees).
Any time the transmission operating angle of 12 degrees is exceeded for an
extended period of time, the transmission must be equipped with an oil pump
or cooler kit to insure proper lubrication.
Lube Change Intervals
Lubricant changes should be based on a combination of the intervals shown
in TCMT-0021 Lubrication Specification MANUAL, and user judgement based
on the application and operating environment. Extending drain intervals
beyond those shown in the tables is not recommended and will put warranties
at risk.
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.
