PERATION
The Trailer Jockey is equipped with an Allison automatic
transmission. Have a qualified technician occasionally check
operation of transmission neutral start switch. If unit starts in
gear, have it repaired.
The Allison transmission installed in your Trailer Jockey is
completely electronically controlled. It is not necessary to
select the right moment to upshift or downshift during chang-
ing road and traffic conditions. The transmission does it for
you. The pushbutton shift selector also provides the ability to
monitor transmission fluid levels and display diagnostic codes.
Having a thorouogh knowledge of the shift selector positions,
available ranges, and when to select them will make vehicle
control and your job easier. Select lower ranges when descend-
ing long grades to reduce wear and tear on service brakes.
Visually check the digital display whenever a button is pushed
to be sure the range selected is shown. For example, if you
press N (Neutral), the digital display should indicate N .
If the digital display is flashing, this indicates the gear
selected was not attained due to an active inhibit.
