CHECKING TRANSMISSION FLUID LEVEL AND
CONDITION
Checking fluid level and condition (color and odor) at
regular intervals will provide early diagnosis
information about the transmission. This information
may be used to correct a condition that, if not
detected early, could result in major transmission
repairs.
IMPORTANT:
When new, automatic transmission fluid is red in
color. As the vehicle is driven, the transmission fluid
will begin to look darker in color. The color may
eventually appear light brown.
A DARK brown color with burnt odor may indicate
excessive fluid deterioration and signal a need for
fluid change.
FLUID LEVEL
When adding or changing fluid, use only DEXRON®-
III
.
Refer to the Maintenance and Lubrication (Section 0)
for maintenance information and servicing interval.
CAUTION:
DO NOT CHECK FLUID LEVEL UNDER THESE
CONDITIONS:
• Immediately after driving at sustained highway
speeds.
• In heavy city traffic during hot weather.
– If vehicle is towing a trailer.
If the vehicle has been operated under these conditions,
shut the engine off and allow the vehicle to “cool” for
thirty (30) minutes. After the cool-down period, restart the
vehicle and continue from step 2 above.
SERVICING
AUTOMATIC TRANSMISSION
CAUTION: Do not overfill.
Overfilling will cause foaming, loss of fluid, abnormal
shifting and possible damage to the transmission.
Techline
1. Parking the vehicle on level ground and apply the
parking brake firmly.
2. Check fluid level with engine running at idle.
NOTE:
Be sure that transmission fluid temperature is below 30°C
(86°F).
3. Move through all gear ranges the selector lever.
4. Move the selector lever to “Park”.
5. Let engine idle for 3 minutes and open the overfill
screw.
6. Let engine idle until a fluid temperature between 32°C
(90°F) and 57°C (135°F) is reached.
7. Add transmission fluid until it flows out over the
overfill screw-opening, then close the overfill screw.

CHANGING TRANSMISSION FLUID
There is no need to change the transmission fluid unless
the transmission is used under one or more of the
following heavy duty conditions.
A: Repeated short trips
B: Driving on rough roads
C: Driving on dusty roads
D: Towing a trailer
If the vehicle is used under these conditions, change the
fluid every 27,000 miles (45,000 km.)
1. Place a large drain pan under the oil pan.
2. Remove the transmission oil drain screw and drain
fluid.
3. Tighten drain screw.

4. Remove the transmission overfill screw and fill
transmission through overfill screw opening, using
DEXRON®-

ATF.
5. Let engine idle until a fluid temperature between 32°C
(90°F) and 57°C (135°F) is reached, then close the
overfill screw.
