4. Check both sides of the dipstick and read the lower
level. Repeat the check procedure to verify the
reading.
5. Safe operating level is within the HOT cross hatch
band on the dipstick. If the fluid level is not within
the HOT band, and the transmission temperature is
between 160°F and 200°F (71°C and 93°C), add
or drain fluid as necessary to bring the level into the
HOT band. If the fluid level is low, add only
enough fluid to bring the level into the HOT band. It
does not take much fluid, generally less than one
pint (0.5L). Do not overfill.
6. If the fluid level is in the acceptable range, push the
dipstick back in all the way, then flip the handle
down to lock the dipstick in place.
Consistency of Readings
Always check the fluid level at least twice using the
procedure described previously. Consistency (repeatable
readings) is important to maintaining proper fluid level. If
readings are still inconsistent, contact your dealer/retailer.
