Allison 2000 Bus series Transmission Gear selection
[WARNING] When leaving the vehicle while the engine is running, the opera-
tor must be sure the transmission is in Neutral, the parking brake is engaged,
and the wheels are chocked. The vehicle may move unexpectedly without
these precautions.
r—reverse. Use reverse to back up the vehicle. The vehicle must stop completely,
with the engine returning to idle speed, before shifting from forward to reverse or
from reverse to forward. If your bus is equipped with a reverse warning signal, it will
activate when shift selector is in reverse.
[CAUTION] Do not idle in “R” (reverse) for more than five minutes. Extended
idle time in “R” (reverse) may cause transmission overheating and damage.
Always select “N” (neutral) whenever time at idle exceeds five minutes.
n—neutral. Use neutral to start the engine, to check vehicle accessories, and for
extended periods of engine idle operation. If the vehicle starts in any other range,
seek service immediately.
[WARNING] Do not allow your vehicle to coast in neutral. This practice can
result in transmission damage. Engine retard and braking assistance is not
available when the transmission is in neutral. It may not be possible to get the
transmission back into gear while the bus is moving.
d—drive. When “D” is selected, the vehicle will begin to move in first gear and the
transmission will upshift automatically through each gear as speed increases. As the
vehicle slows down, the transmission will downshift automatically.
[CAUTION] Do not idle in “D” (drive) for more than five minutes. Extended
idle time in “D” (drive) may cause transmission overheating and damage.
Always select “N” (neutral) whenever time at idle exceeds five minutes.
1, 2, d Gears. Occasionally, the road conditions, load, or traffic conditions will make
it desirable to restrict shifting to a higher gear. Positions “D”, “2”, and “1” provide pro-
gressively greater engine power and braking for going down grades (the lower the
gear, the greater the braking effect).
1 Gear. Use position “1” gear when pulling through mud and deep snow, when ma-
neuvering in tight spaces, or while driving up or down grades. Low gear provides the
vehicle with its maximum power and maximum engine braking power.
Park. If your bus is equipped with a “Park” selection, use it only after coming to a
complete stop, and then apply the parking brake. Do not rely upon the transmission
park pawl position alone to prevent the bus from rolling.
