Allison 2500
WARNING: To avoid sudden, unexpected vehicle movement
and possible personal injury or death:
1. Bring the vehicle to a complete stop.
2. Shift the transmission into position N.
3. Apply the parking brake and make sure it is holding properly.
4. Turn the engine off when you leave the vehicle. Never leave the
vehicle unattended when the engine is running.
This transmission is available with a column-mounted gearshift lever. The
instrument cluster displays the gear positions.
Allison 3000
Note: For more information about this transmission, see the separate
Allison 3000 Series Operator's Manual.
The Allison 3000 series offers two shift modes: Performance and
Economy.
Performance mode gives the best all-around transmission operation. The
transmission defaults to this mode when you start the engine. Pressing
MODE on the shifter switches to Economy mode and illuminates the
Mode ON lamp.
Economy mode provides operation at lower engine RPM while
maintaining adequate performance.
If the engine speed is above idle when a gear is selected using the
shifter, the vehicle does not move; the shifter must be moved to re-select
a gear after the engine speed returns to idle.
Torque Lock
If you park your vehicle on an incline without properly engaging position
P (by shifting into position P before applying the parking brake), the
weight of the vehicle may generate an excessive amount of torque on the
parking pawl. This makes it difficult to shift the transmission out of
position P. Hold the brake pedal down while shifting out of position P,
then release the parking brake.
