NOTE 5 - Transmission Oil Level Check and Fill
CAUTION
Do not overfill transmission. Overfilling may cause aeration
of the transmission oil (milky appearance). If overfilling
occurs, drain transmission oil to bring to proper level.
If fluid level is low, bring to proper level with same oil
grade or type. Mixing of oil grade or type may cause
damage to internal transmission components.
NOTE
Park vehicle on level ground with the parking brake applied.
1. Start the engine and shift the transmission through all drive ranges to fill the
clutch cavities and oil passages, then shift to neutral.
2. Run the engine for at least one minute at 1,000–1,200 rpm to clear the system of
air.
Hot Oil Check (HOT RUN band)
Be sure the temperature of the transmission has reached 120° F (49° C) or above. With
the engine idling and the transmission in NEUTRAL, remove the dipstick (Figure 8)
from the oil fill tube and check the oil level. If the oil registers in the HOT RUN band,
the quantity of oil in the transmission is safe for operating the vehicle. If it registers on
or below the bottom line of the HOT RUN band, add required amount of oil necessary
to bring the oil level to the middle of the HOT RUN band (approximately one quart of
oil is required to move the oil level from the bottom line of the HOT RUN band to the
middle of the HOT RUN band).
Cold Oil Check (COLD RUN band)
Run the engine for one minute at 1,000 rpm to charge the system. With the
transmission oil temperature gauge reading below 120° F (49° C), and the engine idling
with the transmission in NEUTRAL, remove the dipstick (Figure 8) from the oil filler
tube and check the oil level. If the oil level registers in the COLD RUN band the
quantity of oil in the transmission is safe for operating the vehicle. If the oil level
registers on or below the bottom line of the COLD RUN band, add the required
amount of oil necessary to bring the oil level to the middle of the COLD RUN band
(approximately one quart of oil is required to move the oil level from the bottom line
of the COLD RUN band to the middle of the COLD RUN band).
