WARNING
Accidental or intentional introduc-
tion of liquid contaminants into
the environment is in violation of
state, federal, and military regula-
tions. Refer to Lubrication Order
(para. 3-1) for information concern-
ing storage, use, and disposal of
these liquids. Failure to do so may
result in injury or death.
CAUTION
• When checking transmission oil
level, do not permit dirt, dust, or
grit to enter transmission filler
tube. Ensure dipstick handle and
end of filler tube are clean.
Serious internal transmission
damage may result if transmis-
sion is contaminated.
• Do not overfill transmission.
Internal transmission component
damage will result.
NOTE
On M939A2 series vehicles, normal
run level on transmission dipstick
should show between ADD mark
and FULL mark (para. 3-10).
a.
Allow engine to idle. Shift
transmission to neutral and apply
parking brake (para. 2-16).
b.
Withdraw dipstick (2) slowly to
prevent a false reading. If trans-
mission oil temperature gauge
reads 180°F (82°C) or below, level
on dipstick (2) should show between
marks designated for normal run
(1). If transmission oil temperature
is above 220°F (104°C), allow trans-
mission oil to cool by turning
engine off.
