To check the automatic transmission fluid level
properly, the following procedure must be used:
1. The vehicle must be on level ground.
2. The engine should be running at curb idle
speed for a minimum of 60 seconds.
3. Fully apply parking brake.
4. Apply the service brakes and shift the trans-
mission into D (Drive) and R (Reverse) for a
minimum of two seconds in each gear position.
Shift into N (Neutral).
5. The fluid MUST be checked with the transmis-
sion in N (Neutral).
6. Remove the dipstick and feel if the fluid is hot
or warm. Hot fluid is approximately 180°F (82°C),
the normal operating temperature after the vehicle
has been driven at least 25 km (15 miles). The
fluid cannot be comfortably held between the
finger tips. Warm is when fluid is between 85° and
125°F (29° and 52°C).
7. Wipe the dipstick clean and reinsert until
seated. Remove dipstick and note reading.
a. If the fluid is hot, the reading should be in
the crosshatched area marked "OK".
b. If the fluid is warm, the reading should be
above the "Min" hole and below the circle in
the cross hatched area.

If the fluid level is low, add sufficient fluid to bring
to the proper level. Refer to Recommended Flu-
ids, Lubricants and Genuine Parts for correct fluid
type.
Fluid is added through the dipstick tube.
NOTE:
To prevent dirt and water from entering the
transmission after checking or replenishing
fluid, make certain that the dipstick cap is
properly reseated.
Fluid Level Check – 4.7L Engines
Check the fluid level while the transmission is at
normal operating temperature 180°F (82°C). This
occurs after at least 25 km (15 miles) of driving. At
normal operating temperature the fluid cannot be
held comfortably between the fingertips.
To check the automatic transmission fluid level
properly, the following procedure must be used:
1. Operate the engine at idle speed and normal
operating temperature.
2. The vehicle must be on level ground.
3. Fully apply the parking brake and press the
brake pedal.
4. Place the gear selector momentarily in each
gear position ending with the lever in P (Park).
5. Remove the dipstick, wipe it clean and reinsert
it until seated.
6. Remove the dipstick again and note the fluid
level on both sides. The fluid level should be
between the "HOT" (upper) reference holes on the
dipstick at normal operating temperature. Verify
that solid coating of oil is seen on both sides of the
dipstick. If the fluid is low, add as required into the
dipstick tube. Do not overfill. After adding any
quantity of oil through the oil fill tube, wait a
minimum of two (2) minutes for the oil to fully drain
into the transmission before rechecking the fluid
level.
NOTE:
If it is necessary to check the transmission
below the operating temperature, the fluid level
should be between the two "COLD" (lower)
holes on the dipstick with the fluid at approxi-
mately 21°C (70°F) (room temperature). If the
fluid level is correctly established at room
temperature, it should be between the "HOT"
(upper) reference holes when the transmission
reaches 82°C (180°F ). Remember it is best to
check the level at the normal operating tem-
perature.
