Chevrolet 2005 Aveo Owner's Manual page 201

Wait at least 30 minutes before checking the transaxle
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.
To get the right reading, the fluid should be at
normal operating temperature, which is 158°F to 176°F
(70°C to 80°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),
you may have to drive longer.
Checking the Fluid Level
Prepare your vehicle as follows:
•
Park your vehicle on a level place. Keep the engine
running.
•
With the parking brake applied, place the shift lever
in PARK (P).
•
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 PARK (P).
•
Let the engine run at idle for three to five minutes.
Then, without shutting off the engine, follow these steps:
The automatic transaxle dipstick is located toward the
front of the engine compartment, near the power
steering fluid reservoir. See Engine Compartment
Overview on page 5-12 for more information on location.
1. Pull out the dipstick and wipe it with a clean rag
or paper towel.
2. Push the dipstick back in all the way, wait three
seconds and then pull it back out again.
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be between the two
dimples in the hot range.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
