NOTICE
Do not fill above the COLD RUN band if the
transmission fluid is below normal operating
temperature. As fluid temperature increases, so
does the fluid level. Filling above the COLD RUN
band when the transmission is below normal
operating temperature may result in an overfilled
transmission, which causes fluid foaming and
aeration. Fluid foaming and aeration cause
transmission overheating and erratic shifting.
NOTE: Perform a hot check at the first
opportunity after the normal operating
temperature, 160 to 200°F (71 to 93°C) has
been reached.
Hot Check
1. Park the vehicle on a flat, level surface. Apply
the parking brakes and chock the rear tires.
2. Shift the transmission to NEUTRAL.
3. Operate the engine at idle (500 to 800 rpm) until
normal operating temperature is reached. Check
that the sump temperature is 160 to 200°F (71 to
93°C). Check that the converter-out temperature
is 180 to 220°F (82 to 104°C).

4. With the engine idling, remove the dipstick from
the tube and wipe it clean.
5. Insert the dipstick into the tube, then remove it.
6. Check the fluid level reading and repeat the
check procedure to verify the reading. Safe
operating level is within the HOT RUN band on
the dipstick. The HOT RUN band is between the
HOT FULL and HOT ADD marks.
If the fluid level is not within the HOT RUN band,
add or drain fluid as needed to bring the fluid
level within the HOT RUN band. See
approved Allison transmission lubricants, see
Table 3.

Eaton Fuller has a complete listing of approved
lubricants for its transmissions on its internet website.

Draining
IMPORTANT: Manual transmissions filled with
approved synthetic lubricants require a lubricant
drain and fill, and a magnetic plug cleaning
every 500,000 miles (800 000 km), regardless
of the service or vocation of the vehicle. Manual
transmissions with petroleum-based lubricants
require a lubricant drain and fill, and a magnetic
plug cleaning at each Maintenance 2 (M2)
interval. All transmissions, regardless of
lubrication used, also require a check of the
transmission breather at each Maintenance 1
(M1) interval.
1. Park the vehicle on a level surface. Apply the
parking brakes and chock the rear tires.
2. Drain the fluid while the transmission is warm, as
follows.
2.1 Clean the area around the drain plug(s).
Remove the drain plug(s) from the gear
case.
