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.
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.

Gearshift positions
R (Reverse)- Use this position to
back the vehicle. Completely stop
the vehicle before shifting from R
(Reverse) to any forward gear. The
reverse warning signal will sound
when the selector is in R (Reverse).
Reverse has only one gear and
provides the greatest traction. The
Select and Monitor indicators will
display R when reverse is attained.
N (Neutral)- Use N (Neutral) for
starting the engine. If the engine
starts in any gear other than N
(Neutral), the start circuit should be
serviced immediately. 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.
The Select and Monitor indicators
will display N.
Do not allow your vehicle to coast in N (Neutral). Transmission
braking is not available in N (Neutral). This practice can also
result in transmission damage.

D (Drive)- The vehicle will attain
first gear, and as the speed
increases, the transmission will
automatically upshift through each
gear. As the vehicle slows down, the
transmission will automatically
downshift. The Select indicator will
display the highest gear available.
5th or 4th- 2nd gears (depending on application)- Road conditions,
load or traffic can make it desirable to restrict the automatic shifting to a
lower gear. These positions also provide progressively greater engine braking
for descending grades (the lower the gear, the greater the braking effect).
The push button selector uses up
and down arrow buttons to select
the desired gear. The select
indicator will display your choice
and the monitor will display the
gear selected.
1st gear- Use for pulling through mud or deep snow, when maneuvering
in tight spaces or when driving up or down steep grades. 1st gear
provides maximum driving power and engine braking.
In case of engine shutdown (i.e - running out of fuel), while the
transmission is in gear, the transmission will remain in gear until the
ignition key is turned to the OFF position. After the ignition is turned
off, the transmission will automatically shift to N (Neutral) and the
monitor on the shift pad will display N (Neutral) when the ignition key is
turned to the ON position.

This transmission provides five forward speeds in four ranges 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, 4 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.
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.
Do not allow your vehicle to coast in N (Neutral). Engine
braking is not available in N (Neutral). Allowing your vehicle to
coast in N (Neutral) may result in loss of vehicle control and severe
internal transmission damage.
D (Drive-Normal driving position)
In this position, the transmission starts in first gear and automatically
shifts through second, third, fourth and fifth depending on load and
speed demands. When the vehicle is slowing down, the transmission will
automatically downshift. This range is used for highway driving under
normal conditions.
4 and 2 (Fourth 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).
