Whichever is the first of the following:

TES389
Whichever is the first of the following:
 If the TRANS SERVICE indicator
in the shift selector is illuminated
steady for 2 minutes after D
(drive) is selected
 24 calendar months

At time of transmission
overhaul
Prognostics Mode requires the use an Allison approved TES295 or TES389 transmission fluid and Allison High
Capacity filters.
A mixture of TES295 and TES389 fluid must continue to use the TES389 fluid change intervals, until two fluid changes
with only TES295 fluid have occurred, at which time the TES295 schedule may be used.
4.5.1 Oil and Filter Change Interval with
Prognostics Mode Disabled
Allison transmissions are factory fill with Castrol
TranSynd fluid. Oil change must be performed
with the vehicle on a flat and level surface and
with parking brake applied. Oil and filter change
frequency is determined by the severity of service
and operating conditions of the transmission and
by the filter equipment installed. See "TABLE 1 or
TABLE 2" for oil and filter change intervals when
PROGNOSTIC MODE is disabled. More
frequent changes may be required when
operations are subject to high levels of
contamination or overheating. Filters must be
changed at or before recommended intervals.
IMPORTANT NOTE
Your transmission is equipped with High
Capacity filters. High Capacity filters allow for
increased fluid and filter change intervals in
transmissions utilizing TES295 approved fluid
or TranSynd. High Capacity filters eliminate the
requirement of the initial 5000 miles (8000km)
main filter change.
IMPORTANT NOTE
Allison Transmission recommends that
customers use fluid analysis as the primary
method for determining fluid change intervals.
Many customers have a systematical annual
transmission fluid change while, in many cases,
fluid analysis could demonstrate that the
transmission fluid is still in good condition and a
fluid change is not required. In the absence of a
fluid analysis program, the fluid change interval
listed in TABLE 1 & TABLE 2 should be used.
4.5.2 Oil and Filter Change Interval with
Prognostics Mode Enabled
Oil Life Monitor and Filter Life Monitor of the
Prognostics mode provide indicators of required
maintenance actions. They are designed to
maximize fluid and filter utilization. Prognostics
enabled require the use of an Allison
approved TES295 or TES389 transmission
fluid and Allison High Capacity filters. If any
other fluids or filters are used, Prognostic mode
must be disabled. Prognostic information will
not be accurate with any other fluids or filters
