When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission fluid level is when
the engine oil is changed.
Change the fluid and filter at the
intervals listed in Additional
Required Services on page 6-6, and
be sure to use the transmission
fluid listed in Recommended Fluids
and Lubricants on page 6-12.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, you may choose
to have this done at the
dealer/retailer service department.
If adding it yourself, be sure to follow
all the instructions here, or there
could be a false reading on the
dipstick.
Notice: Too much or too little
fluid can damage your
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 you check
your transmission fluid.
Wait at least 30 minutes before
checking the transmission fluid level
if you have been driving:
• When outside temperatures are
above 90°F (32°C).
• 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 180°F to
200°F (82°C to 93°C).
Get the vehicle warmed up by
driving about 15 miles (24 km) when
outside temperatures are above
50°F (10°C). If it is colder than
50°F (10°C), drive the vehicle
in 3 (Third) until the engine
temperature gage moves and then
remains steady for 10 minutes.
A cold fluid 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 50°F (10°C) or
more. If it is colder than 50°F (10°C),
the engine might have to idle
longer. Should the fluid level
be low during this cold check,
check the fluid hot before adding
fluid. Checking the fluid hot gives
a more accurate reading of the
fluid level.
