Prognostic Features
5th Generation Electronic Controls Shift
Selectors display prognostics in text form to
provide at-a-glance status of Oil Life, Filter Life
and Transmission Health.
The WRENCH ICON will illuminate briefly after you turn
the key to the run position on your Allison-equipped
vehicle to indicate that prognostics are enabled. If the
WRENCH ICON remains on or flashes, this indicates there
is a service issue relating to clutch, filter or fluid life.

The status of the oil life is displayed as a percentage
(OIL LIFE 100%) until fluid is due for a change.
Filter Life Monitor
The status of filter life is displayed as OIL FILTERS OK
and alerts when filters are due for a change with REPLACE FILTERS.
Transmission Health Monitor (not available for TC10)
The status of transmission health is displayed as HIGH to LO.
