Hot Check Procedure
Use this procedure to check the transmission fluid level
when the transmission fluid temperature is between
160°F and 200°F (71°C and 93°C).
The hot check is the most accurate method to check the
fluid level. The hot check should be performed at the first
opportunity in order to verify the cold check. The fluid
level rises as fluid temperature increases, so it is
important to ensure the transmission temperature is
within range.
1. Locate the transmission
dipstick at the
rear of the engine
compartment, on the
passenger side of
the vehicle.
See Engine Compartment Overview on page 5-14
for more information.
2. Flip the handle up, and then pull out the dipstick
and wipe it with a clean rag or paper towel.
3. Install the dipstick by pushing it back in all the way,
wait three seconds, and then pull it back out again.
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.
