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 20,000 miles (32,000 km).

1. Place a large drain pan under the oil pan.
2. Remove the transmission oil drain screw (2) and drain

4. Remove the transmission overfill screw (1) and fill

transmission through overfill screw opening, using
DEXRON



–III ATF.

NOTE: Add transmission fluid until it flows out over the
overfill screw opening.

5. Let engine idle until a fluid temperature between 32

°

C

(90

°

F) and 57

°

C (135

°

F) is reached.

6. Add transmission fluid until it flows out over the overfill

screw opening, then close the overfill screw (1).

Torque: 38 N

•

m (28 lb ft)

NOTE: To prevent fluid leaks, the overfill screw and oil
drain screws gasket must be replaced each time these
screws are removed.
