With an Allison MD-equipped vehicle, it is not necessary to select the right moment to upshift or down-
shift during the changing road and traffic conditions. The Allison MD does it for you. However, knowledge
of the gear ranges and when to select them will make vehicle control and your job even easier.
MD 3060 GEAR SELECTION
WARNING: In the event the operator leaves the vehicle, even momentarily, while the engine is running,
be sure that the transmission is in Neutral, parking brake and/or emergency brakes are set and properly
engaged, and the wheels are chocked. Unexpected and possible sudden vehicle movement may occur if
these precautions are not taken.
R - Reverse
The vehicle must be completely stopped before shifting from Forward to Reverse or from Reverse to
F orward. The SELECT indicator will display R and the MONITOR will display R when Reverse is attained.
N - Neutral
Use Neutral to start the engine, to check vehicle accessories, and for extended periods of engine idle
operation. Under normal operation, the transmission is directed by the ECU to Neutral during the start-up
procedure. This occurs automatically with the push-button selector. If the vehicle starts in any range except
N
eutral, seek service immediately. Neutral is also used during stationary operation of the power takeoff (if
your vehicle is equipped with a PTO). The SELECT indicator will display Neutral and the MONITOR will
display Neutral.
WARNING: Do not allow your vehicle to coast in Neutral. This practice can result in transmission dam-
age. Also, no engine braking is available in Neutral.
D - Drive
The vehicle will attain first gear when D is selected, and as the speed increases, the transmission will
upshift automatically through each gear. As the vehicle slows down, the transmission will downshift auto-
matically. The SELECT indicator will display the highest gear available and the Monitor will display the
current operating gear.
2, 3, 4, 5 Gears
Occasionally, the road conditions, load, or traffic conditions will make it desirable to restrict the automatic
shifting to a lower gear. Positions 2, 3, 4, 5, provide progressively greater engine braking for going down
grades (the lower the gear, the greater the braking effect). The push-button selector utilizes arrow buttons.
Push the Up or Down arrow to the desired gear. The SELECT indicator will display your choice and the
MONITOR
will display the selected gear when it is attained.
1st Gear
Use position (1) gear when pulling through mud and deep snow, when maneuvering in tight spaces, or
while driving up or down grades. Low gear provides the vehicle with its maximum driving power and
maximum engine braking power.
The transmission incorporates a hold feature to prohibit upshifting above the gear selected during nor-
mal driving. For downhill operation, however, the transmission may upshift above the highest selected gear
when the engine governed speed is exceeded and damaging engine overspeed is a possibility.
DO NOT SHIFT LIGHT
The "DO NOT SHIFT LIGHT" is located on the shifter cover. The electronic control system is programmed
to inform you if operating parameters have been exceeded and automatically take action to protect the opera-
tor, vehicle, and transmission. A diagnostic code will be registered when the DO NOT SHIFT light is on and
also when other conditions are diagnosed which do not require the DO NOT SHIFT light to be on.
Every time the engine is started, the DO NOT SHIFT light comes on then goes off after a few seconds.
This momentary lighting is to show that the lighting circuit is working properly. If the light does not come on
during engine start, service should be requested immediately.
