GENERAL MAINTENANCE
HOT CHECK
COLD CHECK
NOTE:
The purpose of the cold check is to determine if the transmission
has enough oil to be safely operated until a hot check can be made.
A cold check may be made when the sump temperature is 60-120ºF
(15-49ºC).
Run the engine for at least 1 minute to clear the oil system of air.
With the engine running at idle, wipe the dipstick clean and check the oil
level. any level within the COLD RUN (REF FILL) band is satisfactory for
operating the vehicle. If level is not within the COLD RUN (REF FILL) band,
add or drain oil as necessary to bring the level to the middle of the COLD
RUN (REF FILL) band.
Perform a hot check at the first opportunity after normal operating
temperature (160-200ºF, 71-93ºC) is reached.
NOTE:
The hot and cold check level marks are on opposite sides of the
dipstick.
NOTE:
The oil must be hot to ensure an accurate check. The oil level
rises as temperature increases.
Operate the transmission in a drive range until normal operating
temperature (160-200ºF, 71-93ºC) is reached.
Park the vehicle on level ground, shift to (N) neutral and apply the
park brake. Let the engine run at idle speed.
Wipe the dipstick clean and check the oil level. The safe
operating level is anywhere within the HOT RUN band on the
dipstick.
If the level is not within this range, add or drain oil as necessary to
bring the level to the middle of the HOT RUN band.
