Fluid Level Checking
Cold Check
IMPORTANT: The only purpose of the Cold
Check is to determine if the transmission has
enough fluid to be safely operated until a Hot
Check can be made.
1.
A cold check may be made when the sump tem-
perature is 60 to 104°F (15 to 40°C).
2.
Run the engine for at least one minute to clear
the fluid system of air.
3.
With the engine running, wipe the dipstick clean
and check the fluid level. Any level within the
COLD RUN (lower) band is satisfactory for oper-
ating the vehicle. If the level is not within the
COLD RUN band, add or drain fluid until it
reaches the middle of the COLD RUN band. See
Fig. 7
.
4.
Perform a hot check at the first opportunity after
normal operating temperature, 160 to 200°F (71
to 93°C), is reached.
Hot Check
1.
Operate the transmission in a Drive (D) range
until normal operating temperature, 160 to 200°F
(71 to 93°C), is reached.
NOTE: The fluid must be warm to ensure an
accurate check. The fluid level rises as tempera-
ture increases.
2.
Park the vehicle. Shift to Neutral (N) and set the
parking brake. Let the engine run at idle.
3.
Wipe the dipstick clean and check the fluid level.
A safe operating level is any level within the HOT
RUN (upper) band on the dipstick. See
4.
If the fluid is not within this range, add or drain
fluid as needed to bring the level to the top of
the HOT RUN band. See
for approved
automatic transmission lubricants, and
and
for automatic transmission lubricant
capacities.
