ALLISON TRANSMISSION

The transmission is fully automatic: Proper ranges
should be automatically selected according to
driving speeds to improve vehicle performance
and control. The speed ratio of the power converter
changes automatically as vehicle speed increases
and direct-drive goes in and out as necessary. The
speed ratio is modulated by vehicle speed and
accelerator pedal position. You will find the
complete transmission operation instructions and
driving tips in the Allison 5th Generation Bus
Series Operator's Manual
Technical Publication web site.

OPERATION

When a button is depressed on the transmission
control pad, the corresponding letter or number is
displayed indicating the transmission is ready to
operate in the selected range. If the transmission
control module (TCM) detects a serious problem in
the transmission, the CHECK telltale lights on the
dashboard.
