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 5-14
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.
4. Check both sides of the dipstick and read the
lower level. The fluid level must be in the
cross-hatched area.
5. If the fluid level is in the acceptable range, push
the dipstick back in all the way.
