fluid. Oil change must be performed
with the vehicle on a flat and level surface and
with parking brake applied. Oil and oil 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, TABLE 2 or TABLE 3"
for oil and
filter change intervals. 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
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.
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. 6) 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. 6).
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).
6. Inspect the drain plug and O-ring. Replace if
necessary. Reinstall the drain plug and tighten
to 18-24 lbf-ft (25-32 Nm).
7. Reinstall transmission protective panel
