TRANSMISSION FLUID LEVEL
WARNING
To prevent personal injury, do not service
transmission wearing loose clothing. Stand
clear of the engine and rotating
components while checking the oil level.
CAUTION
Do not mix fluid types or brands because of
possible incompatibility.
CAUTION
Use clean fluid and containers when filling
transmission. Never use containers that
have contained water or anti-freeze
(Glycol).
ALLISON TRANSMISSION FLUID LEVEL
The transmission fluid level can be checked with
the dipstick or with the use of the shift selector
display. For more information on how to use the
shift selector display to check the transmission
oil level, refer to Appendix C under “Allison
transmission oil level check using the
pushbutton shift selector” in this manual.
TRANSMISSION FLUID DIPSTICK
The transmission fluid level dipstick is accessible
through the engine compartment rear door and
is located on the left side of the engine.
To check the transmission fluid level, a "cold
check" and a "hot check" must be performed. A
cold check must be made when the transmission
fluid is between 60
o
F and 120
o
F (16
o
C and 50
o
C).
NOTE
Perform the cold check first to verify the
transmission fluid level before performing the
hot check.
To prevent dirt and foreign matter from entering
the transmission, clean the end of the oil fill
tube before removing dipstick. To remove
dipstick, unscrew filler cap approximately three
turns and pull out dipstick.
Cold Check
Run the engine until the transmission fluid
temperature is between 60
o
F and 120
o
F (16
o
C
and 50
o
C). With the engine idling, make sure the
parking brake is applied and the transmission is
in neutral (N). Remove and wipe the dipstick
with a clean cloth. Check oil level. If the oil level
is within the COLD RUN band, the oil level is
correct and a hot check can be performed. If the
oil level is on or below the lower line of the COLD
RUN band, add oil until the level lies within the
COLD RUN band. If the oil level is above the
COLD RUN band, drain oil until the level is within
the band.
