Fluid loss with filter change only
When changing main and lube filters at
recommended intervals, approximate fluid loss
for each filter as follows:
Main filter = 2 quarts (1.9 liters)
Lube filter =8 quarts (7.6 liters)
3.5.2 Refill
transmission
The amount of refill fluid is less than the amount
used for the initial fill. Fluid remains in the
external circuits and transmission cavities after
draining the transmission.
NOTE
Quantities listed below are approximations and
do not include external oil cooler lines.
Using the oil level dipstick filler tube, refill with
24 US qts (23 liters), 28 US qts (26.5 liters) if
equipped with retarder, and check the oil level
using the
Fluid Level Check Using
Pushbutton Shift Selector
procedure in this
section. Add transmission fluid according to
pushbutton shit selector fluid level check.

CLEANING AND INSPECTION OF
ALLISON AUTOMATIC TRANSMISSION
The exterior of the transmission should be
cleaned and inspected at regular intervals. The
length of service and severity of operating
conditions will determine the frequency of such
inspections. Inspect the transmission for:
1. Loosen bolts (transmission and mounting
components);
2. Oil leaks (correct immediately);
3. Loose, dirty, or improperly adjusted throttle
sensor linkage;
4. Damaged or loose oil lines;
5. Worn or frayed electrical harnesses, improper
routing;
6. Worn or out of phase drive line U-joint and slip
fittings.
CAUTION
DO NOT pressure wash the transmission
electrical connectors. Water and detergent will
cause the contacts to corrode or become
faulty.
3.6.1 Breather
The breather is located on the engine, flywheel
side near the valve cover. It serves to prevent
pressure build-up within the transmission and
must be cleaned to keep the passage opened.
The prevalence of dust and dirt will determine the
frequency at which the breather requires
cleaning. Use care when cleaning the engine.
Spraying steam, water or cleaning solution
directly at the breather can force the water or
solution into the transmission. Always use care
when removing the hose connector from
transmission to prevent the entry of foreign
matter.
4. TRANSMISSION OIL COOLER REMOVAL
4.1
TRANSMISSION WITHOUT RETARDER
Stop engine and allow engine to cool. Close
both heater line shutoff valves (refer to Section
05
‘’Cooling’’
).
To drain the cooling system, proceed as per
Section 05
‘’Cooling’’
, paragraph 5: Draining. If
the cooling system is contaminated, flush
