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 & TABLE 3 should
be used.
IMPORTANT NOTE
Your transmission is equipped with High
Capacity filters. High Capacity filters allow for
increased fluid and filter change intervals in
transmissions utilizing TES 295 approved
fluid/TranSynd™. High Capacity filters eliminate
the requirement of the initial 5000 miles
(8000km) main filter change.
Former Gold Series filter kits are completely
cancelled and serviced with current High
Capacity filter kits. However, if you are using
stocked Gold Series filter kits with TES 295
approved fluid/TranSynd™, use TABLE 3 for oil
and filter change intervals.
o 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 requires the use of 100%
TranSynd™ or an Allison approved TES-295
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 and could result in missed
maintenance activities resulting in transmission
damage.
IMPORTANT NOTE
The following schedule is to be used with
Prognostics enabled.
100% concentration of TES-295 Allison
approved fluids and Allison High Capacity
Filters is required. Less than 100%
concentration of TES-295 Allison approved
fluids are considered a mixture and shall not be
used with Prognostics mode or this change
schedule. Utilization of previous Non-TES 295
fluid/filter change intervals (Table 1) is required.
General or Severe Vocation
FLUIDS
Prognostics
enabled
Change fluid when indicated by
TRANSMISSION SERVICE indicator
or 60 month (five years) whichever
occurs first. In addition, change filters
with fluid.
FILTERS
Prognostics
enabled
Change filters (Main & Lube) when
indicated by TRANSMISSION
SERVICE indicator between fluid
change or 60 month (five years)
whichever occurs first.
o Changing The Transmission Oil And Oil
Filters
The procedure for changing the transmission oil
and oil filters is as follows:
Drain
1. The transmission should be at an operating
temperature of 160ºF (71ºC) to 200ºF (93ºC)
when the oil is drained. This will ensure
quicker and more complete fluid drainage.
NOTE
Remove transmission protective panel located
underneath transmission for easier access.
2. Remove the drain plug from under the
transmission (Fig. 7) and allow the oil to drain
into a suitable container. Check the condition
of the oil as described previously.
3. To replace the integral filters, remove twelve
bolts (6 on each cover), two filter covers, two
O-rings, two square cut seals and the two
filters from the bottom of the control module
(Fig. 7).
4. To install filters, pre-lube and install the two O-
rings, the two square cut seals followed by the
filters (lube the O-ring in filter cartridge only)
into the filter compartment. Index each
filter/cover assembly to holes in channel
plate/sump. Push the cover assembly in by
hand to seat the seals.
CAUTION
Do not use bolts to draw the cover to sump.
This can damage the cover, seal, or sump.
5. Install twelve bolts and both covers, and then
tighten to 38-45 lbf-ft (51-61 Nm).
