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), you may have to
drive longer.
Checking the Fluid Level
Prepare the 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. For the 3.9L V6 engine,
locate the transmission
fluid dipstick top which
is a round loop with
this symbol.
See Engine Compartment Overview on page 6‑14
for more information on location.
2. Pull out the dipstick and wipe it with a clean rag or
paper towel.
3. Push it back in all the way, wait three seconds, and
then pull it back out again.
