Eaton Fuller Five and Six-Speed
Transmissions and TTC Spicer
Seven-Speed Transmissions
These transmissions have gears that automatically
synchronize when you shift up or down (except 1 (First)
gear on the five-speed and seven-speed transmission
which is unsynchronized). Choose the gear that will
maintain the road speed you want while keeping
the engine above two-thirds of the governed speed.
When the engine speed drops below two-thirds of the
governed speed, shift into the next lower gear before
your engine begins to lug. When you shift down, be sure
to double-clutch if required.

Eaton Fuller Nine and Ten-Speed
Non-Synchronized Manual
Transmissions
If the vehicle has one of these transmissions the engine
rpm and road speed must match when upshifting and
downshifting. The label above the windshield will tell you
the operating basics you need to know.
The following are driving tips.
•
Always choose an initial starting gear suitable for
the load and terrain.
•
Always use double-clutching procedures when
shifting.
•
Never move the range shift lever to the LO speed
gear position after HI range preselection, or
anytime the transmission is in the HI range.
•
Never move the range knob or lever with the shift
lever in N (Neutral) while the vehicle is moving.
•
Never make a range shift while moving in
R (Reverse).
Clutch Brake (Vehicles with
Non-Synchronized Transmission)
A clutch brake is used to stop transmission input shaft
rotation so that 1 (First) or R (Reverse) gear selection
can be initiated when the vehicle is at a standstill
and the engine is idling.
Press the clutch pedal all the way down to the floorboard
to apply the clutch brake.
When using the clutch brake, disengage the clutch pedal
and shift the transmission into either the initial starting
gear or R (Reverse). If the tooth-butting occurs between
the clutching teeth, re-engage the clutch while applying
light pressure to the shift lever. This will provide for a
smooth shift into either 1 (First) or R (Reverse) gear.
Notice: Using the clutch brake for shifting into any
gear other than 1 (First) or R (Reverse) may cause
premature wear of the clutch brake and make gear
shift effort more difficult. Do not use the clutch brake
for shifting after engaging 1 (First) or R (Reverse).
