COLD CHECK
The Cold Check determines if the transmission has enough
fl
uid to be operated
safely until a Hot Check can be made.
NOTE:
The correct
fl
uid level
can not be determined
unless the
transmission is in a level position.
CAUTION:
DO NOT start the engine until the presence of sufficient
transmission
fl
uid has been con
fi
rmed. Remove the transmission
fl
uid
dipstick and be sure the static
fl
uid level is near the HOT FULL mark.
CAUTION:
The
fl
uid level rises as
fl
uid temperature rises. DO NOT
fi
ll
the transmission above the “COLD CHECK” band if the transmission
fl
uid is below normal operating temperatures. During operation, an
overfull transmission can become overheated, leading to transmission
damage.
A cold check may be made after initial start-up and the presence of transmission
fl
uid has been con
fi
rmed (the sump
fl
uid temperature is then typically 16°–49°C
(60°–120°F). To perform a COLD CHECK, do the following:
1. Start the engine and run it at idle (500–800 rpm) in
N
(Neutral) for about
one minute.
2. Shift to
D
(Drive) and then to
R
(Reverse) to clear the hydraulic circuits of
air.
3. Shift to
N
(Neutral) and leave engine at idle.
4. Move the vehicle to a level surface, put transmission in
N
(Neutral), and
set the parking brake.
5. With the engine idling (500–800 rpm), shift to
D
(Drive) and then to
R
(Reverse) to clear air from the hydraulic circuits.
6. Shift to
N
(Neutral) and leave engine at idle.
7. Remove the dipstick and wipe it clean. Insert the dipstick into the
fi
ll tube,
pushing down until it stops.
8. Remove the dipstick and observe the
fl
uid level. If the
fl
uid on the dipstick
is within the COLD CHECK band, the level is satisfactory. If the
fl
uid
level
is not
within this band, add or drain
fl
uid as necessary to bring the
level within the COLD CHECK band.
9. Perform a Hot Check at the
fi
rst opportunity after normal operating
temperature (71°–93°C; 160°–200°F) is reached.
