4-156. TRANSMISSION ASSEMBLY MAINTENANCE (Continued).
c. Cold check.
(1) Be sure the oil temperature is between 60-120° F
(16-50°
C). With the engine idling and the
transmission in neutral (N), wipe the dipstick clean and
check the oil level. If the oil level registers in the REF
FILL band, the quantity of oil in the transmission is
sufficient to operate the vehicle until normal operating
temperature (160-200° F; 71-93° C) is reached. If the
oil level registers on or below the bottom line of the
REF FILL band, add oil to bring the level within the
band. If the oil level registers above the REF FILL
band, drain oil to bring the level within the band. Then
operate the vehicle and make a hot check when
normal operating temperature is reached.
The oil level rises as oil temperature increases.
Do not fill above the REF FILL band before the
transmission
reaches
normal
operating
temperature.
d. Hot check.
(1) Be sure the oil temperature is between 160-200° F
(71-93°
C). With the engine idling and the
transmission in neutral (N), wipe the dipstick clean and
check the oil level. If the oil level registers in the HOT
RUN band or between ADD and FULL, the oil level is
satisfactory to continue operation of the vehicle. If the
oil level registers on or below the bottom line of the
HOT RUN band or below the ADD line, add oil to bring
the oil level to the middle of the band.
e. Adjusting oil level.
(1) About one U.S. quart (0.946 liter) of transmission oil
(Appendix D, Item 38) is required to raise the oil level
from the bottom of the band to the top of the band. If a
hot check shown the oil level is above the HOT RUN
line, drain oil until it is level with the top of the REF
FILL band in a cold oil check. Drain oil to bring the oil
level within the band.
