FLUID LEVEL CHECK AND FILL PLUG LOCATIONS
FLUID LEVEL CHECKING PROCEDURE
Start the engine as it must be running to properly
check the fluid level. Depress the brake pedal and
move the shift lever through all of the gear ranges,
pausing a few seconds in each range. Return the shift
lever to the PARK range.
Raise the vehicle on a hoist. The vehicle must be
level with the engine running and the shift lever in
the PARK range.
Caution:
The engine must be running when Check/Fill plug
is removed, or excessive fluid loss will occur.
Transmission fluid may be hot, and since the actual
fluid level is unknown, stand clear and take
precautions with protective clothing when removing
the plug. Have a container ready to capture any lost
fluid. Do not turn the engine off with the fill plug
removed as you can be injured by hot transmission
fluid being expelled from the Check/Fill plug
opening.
Let the transmission fluid temperature rise until it
has reached a temperature of 90-125°F (30-50°C).
Remove the transmission fill plug with care as
described above. Use Figure 13 for the locations as
they differ from gasoline models to diesel models.
The fluid should trickle from the plugs opening.
Add Dexron® III automatic transmission fluid in
increments of 0.5 L (0.5 quart) until the fluid drains
from the threaded opening. Torque specification for
the Check/Fill plug is 15 ft.lb.
