1. Clean all dirt off the reservoir.
2. Remove the filler 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 ºCOLDº
range on the dipstick. Similarly, if it is hot, the fluid level
should be in the ºHOTº 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 filler cap, visually check the
steering box case, vane pump and hose connections for
leaks or damage.
