DRIVING WITH A MANUAL TRANSMISSION, IF EQUIPPED
Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a
failure of the engine, transmission or clutch components.
To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold the vehicle
at a standstill on an upgrade as when waiting for a traffic light.
Manual transmission shift patterns
are displayed on the shift lever
knob.
Study this information carefully before you drive the vehicle even though
you may be familiar with similar units. Do not attempt to drive the
vehicle without knowing the exact shift pattern of the transmission.
Consult your authorized dealer if any questions exist as to the shifting
instructions posted in your vehicle.
Do not coast the vehicle with the clutch pedal depressed or with
the transmission in neutral. This practice could result in loss of
vehicle control.

Always use a gear ratio low enough to allow the engine to operate above
the minimum engine operation speed range. Do not lug the engine. When
more power is required, shift to a lower gear and accelerate the engine
near the governed speed.
Driving hints
The following driving hints are provided as a brief, general guide in
operating the different manual transmissions used in your vehicle.
•Always use the lowest gear to start the vehicle.
•Do not slam or jerk lever into gear.
•When shifting into 1 (First) or R (Reverse) with vehicle standing still,
quickly release and depress the clutch pedal (if necessary to complete
gear engagement).
Operating the Eaton FS-4205A and FS-5205A 5–speed
transmissions
The 5-speed transmission is
equipped with five forward gears
and one reverse. All forwards gears
are synchronized. The shift pattern
is embossed on the gear shift knob.
Do not shift the transmission into R (Reverse) while the vehicle is
moving as this could damage the transmission.
To go forward
With the engine idling, depress the
clutch pedal and shift into 1 (First).
Engage the clutch while pressing
the accelerator to start forward.
Operate the clutch and upshift as
required by driving conditions.

Removing key from ignition
•Turn the ignition key to
position 2.
•Push the release lever forward
and rotate the key towards you
and remove.
Power-take off operation (PTO) with a manual transmission
Transmission-mounted power take-off units are available for local
installation on Ford vehicles. See your Body Builder’s Layout Book for
restrictions on use and installation of power take-off units.
To engage the PTO unit, stop the vehicle and place the transmission
control in neutral. Depress the clutch and allow the gears to stop
rotating, then engage the PTO unit. The PTO can also be selected with
the transmission in gear as long as the clutch is depressed.

When operating the PTO unit with the vehicle stationary, first set the
parking brake (chock the wheels if the vehicle is on a hill or other
unlevel surface).
DRIVING WITH AN AUTOMATIC TRANSMISSION, IF EQUIPPED
Allison automatic transmission
Do not allow your vehicle to coast in N (Neutral). Transmission
braking is not available in N (Neutral). Allowing the vehicle to
coast in N (Neutral) could result in loss of vehicle control and severe
transmission damage.
The Allison automatic transmissions are a torque converter type, full
power shifting and fully automatic. They also have the added flexibility
of manually selecting and holding in the lower drive ranges which permit
the drive selection of the most suitable gear range to match varying road
and load conditions. To prevent destructive overspeeding of the engine,
the hold feature is not infinite, resulting in upshifts from the hold range
to the next higher range at some speed above the no-load governed
speed of the engine.
Allison AT-545
These transmissions have no P (Park) position. Before leaving
the driver’s seat, always shift into N (Neutral) and set the
parking brake. Shut off the engine and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
This transmission provides four forward speeds and one reverse range.
R (Reverse)
Use this position to back the vehicle. Completely stop the vehicle before
shifting from R (Reverse) to any forward gear (1, 2, 3 or D). The reverse
warning signal will sound when the selector is in R (Reverse). Reverse
has only one gear and provides the greatest gear reduction.
Driving
102
Page 103 of 208

N (Neutral)
Place the selector in N (Neutral) before starting the engine. Shift to N
(Neutral) and set the parking brake any time the engine is to be running
while the operator is not at the controls. The engine should be at idle
speed when any shift from N (Neutral) to a drive range is made.
D (Drive-Normal driving position)
The transmission starts in first gear and automatically shifts through
second, third and fourth depending on load and speed demands. This
range is used for highway driving under normal conditions.
3 and 2 (Third and Second)
Use these ranges when road, load or traffic conditions require a lower
gear. These ranges provide greater engine braking than D (Drive). When
conditions are improved that no longer require these lower gears, shift
back to D (Drive).
1 (First)
The transmission has to be manually shifted into 1 (First) and will not
shift into a higher gear. This range is used for extra heavy loads or where
maximum reduction is required.
Allison MD Series transmissions
These transmissions have no P (Park) position. Before leaving
the driver’s seat, always shift into N (Neutral) and set the
parking brake. Shut off the engine and remove your ignition key.
Always use wheel chocks for hilly or off-road parking. Unexpected and
possibly sudden vehicle movement may occur if these precautions are
not taken.
These transmissions are electronically controlled and have a push button
shifter. MD transmissions are available in five- or six-speed driving
ranges.

The push button shifter has a R
(Reverse), N (Neutral) and D
(Drive) selections as well as a
MODE button, up arrow (for
upshifts) and a down arrow
(downshift) and a digital display.
When a range button is pressed, a
tone will sound, the SELECT
indicator displays a chosen
operation (if the Electronic Control
Unit determines the shift is
acceptable) and the transmission
will shift to the starting range. In D
(Drive), selection of a specific gear
can be accomplished by pressing the
up or down arrow button. If the
CHECK TRANS light (located on the instrument panel) is illuminated,
the shifter control pad may be disabled, tones will not be heard, shifts
may not occur and directional shift changes will not be able to be
performed.
The MODE button may be used to
activate a second shift schedule
(this is typically programmed for
Economywhich will enable the
transmission to shift at a lower RPM
to conserve fuel).
These transmissions incorporate a hold feature to prohibit upshifting
above the gear selected during normal driving. During downhill
operation, the transmission may upshift from the selected gear if the
Electronic Control Unit detects the possibility of engine damage from
exceeding the governed engine speed.
