Allison Transmission Emergency Vehicle Series User Manual

INTRODUCTION
Vehicle manufacturers may choose different types of shift selectors for their
vehicles. The shift selector in your Allison-equipped vehicle will be similar to one
of the pushbutton or lever styles shown above.
With an Allison-equipped vehicle, it is not necessary to select the right moment to
upshift or downshift during changing road and traffic conditions. The Allison
Emergency Vehicle Series transmission does it for you. However, knowledge of
the shift selector positions, available ranges, and when to select them, make
vehicle control and your job even easier. Select lower ranges when descending
long grades (with or without retarder) to reduce wear on service brakes. Refer to
the Range Selection table at the end of this section for related information.
