How to Check
Because this operation can be a
little difficult, the decision may be
made to have this done at the
dealership service department.
If the decision is made to perform
this operation, be sure to follow all
the instructions here, or a false
reading on the dipstick could result.
Notice: Too much or too little
fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Wait at least 30 minutes before
checking the transmission fluid level
if the vehicle has been driven:
.
When outside temperatures are
above 32°C (90°F).
. At high speed for quite a while.
. In heavy traffic — especially in
hot weather.
. While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is 82°C to 93°C
(180°F to 200°F). Get the vehicle
warmed up by driving about 24 km
(15 mi) when outside temperatures
are above 10°C (50°F). If it is colder
than 10°C (50°F), drive the vehicle
until the engine temperature gauge
moves and then remains steady for
10 minutes.
A cold check can be made after the
vehicle has been sitting for eight
hours or more with the engine off,
but this is used only as a reference.
Let the engine run at idle for
five minutes if outside temperatures
are 10°C (50°F) or more. If it is
colder than 10°C (50°F), the engine
may have to idle longer. Should the
fluid level be low during this cold
check, the fluid must be checked
when hot before adding fluid.
Checking the fluid hot will give you
a more accurate reading of the fluid
level.
Checking the Fluid Level
Prepare the vehicle as follows:
. Park the vehicle on a level
place. Keep the engine running.
. With the parking brake applied,
place the shift lever in P (Park).
. With foot on the brake pedal,
move the shift lever through
each gear range, pausing for
about three seconds in each
range. Then, position the shift
lever in P (Park).
. Let the engine run at idle for
three minutes or more.
