the dipstick. Do not overfill so the level is above
the upper marking on the dipstick. Add oil through
the oil filler pipe as required in order to maintain
level within the safe range.

DANGER
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 antifreeze (Glycol).
Allison Automatic 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
" OIL LEVEL CHECK USING THE
PUSHBUTTON SHIFT SELECTOR " on page 2
in Appendix B.
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

parking brake is applied and the transmission is
in neutral (N). Shift transmission from forward (D)
to reverse (R) and back into neutral (N) to fill
clutch cavities with fluid. Remove and wipe the
dipstick with a clean cloth. Check fluid level. If
the fluid level is within the COLD RUN band, the
fluid level is correct and a hot check can be
