Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRON
II
or
III.
If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60
C – 80 C or 140 F – 175 F). You may also check the level
when the fluid is cold (about room temperature, 10 C – 30 C
or 50 F – 85 F) if the engine has not been run for about five
hours.

1. Clean all dirt off the reservoir.
2. Remove the reservoir cap by turning it counterclockwise
and wipe the dipstick clean.
3. Reinstall the reservoir cap.
4. Remove the reservoir cap again and look at the fluid level.
If the fluid is cold, the level should be in the ”COLD” range on
the dipstick. Similarly, if it is hot, the fluid level should be in the
”HOT” range. If the level is at the low side of either range, add
automatic transmission fluid DEXRON
II or III to bring the
level within the range.
5. After replacing the reservoir cap, visually check the
steering box case, vane pump and hose connections for leaks
or damage.
