3. Install the dipstick by pushing
it back in all the way; wait
three seconds, and then pull it
back out again.

and read the lower level. Repeat
the check procedure to verify the
reading.
5. If the fluid level is below the
COLD check band, add only
enough fluid as necessary to
bring the level into the COLD
band. It does not take much
fluid, generally less than 0.5 Liter
(1 Pint). Do not overfill.
6. Perform a hot check at
the first opportunity after the
transmission reaches a normal
operating temperature between
71°C to 93°C (160°F to 200°F).
7. 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.
Hot Check Procedure
Use this procedure to check the
transmission fluid level when the
transmission fluid temperature is
between 71°C and 93°C (160°F
and 200°F).
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.
