Chevrolet Impala Owner Manual - 2011
10-12 Vehicle Care
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 you have been driving:
.
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), the vehicle may have
to be driven longer.
Checking the Fluid Level
Prepare your vehicle as follows:
1. Park the vehicle on a level
place. Keep the engine running.
2. With the parking brake applied,
place the shift lever in P (Park).
3. With your 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).
4. Let the engine run at idle for
three to five minutes.
Then, without shutting off the
engine, follow these steps:
1. Pull out the dipstick and wipe it
with a clean rag or paper towel.
The transmission fluid dipstick
handle is the black loop with this
symbol on it. It is located near
the rear of the engine
compartment.
See Engine Compartment
Overview on page 10‑6 for more
information on location.
2. Push it back in all the way, wait
three seconds, and then pull it
back out again.
