Checking the Exhaust System

ELS001OP

Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage, loose connections, chafing or deterioration.

Checking the Automatic Transmission Fluid (ATF)

ELS001OQ

1.

Before driving, the ATF level can be checked at ATF tempera-
tures of 30

°

 to 50

°

 C (86

°

 to 122

°

 F) using the “COLD” range on

the ATF level gauge as follows:

a.

Park the vehicle on a level surface and set the parking brake.

b.

Start the engine and move the selector lever through each gear
position. Shift the selector lever into the “P” position.

c.

Check the ATF level with the engine idling.

d.

Remove the ATF level gauge and wipe it clean with a lint-free
paper.

CAUTION:

When wiping the ATF from the ATF level gauge, always use
a lint-free paper, not a cloth.

e.

Re-insert the ATF level gauge into the charging pipe until the
cap contacts the top of the charging pipe as shown.

CAUTION:

To check ATF level, insert the ATF level gauge until the cap
contacts the top of the charging pipe, with the gauge
reversed from the normal inserted position.

f.

Remove the ATF level gauge and note the ATF level. If the ATF
level is at low side of range, add ATF to the transmission
through the charging pipe.

CAUTION:

Do not overfill the transmission with ATF.

g.

Install the ATF level gauge and the ATF level gauge bolt.

2.

Warm up the engine and transmission.

3.

Check for any ATF leaks.

4.

Drive the vehicle to increase the ATF temperature to 80

°

 C (176

°

 F).

5.

Allow the ATF temperature to fall to approximately 65

°

C (149

°

F). Use the CONSULT-II to monitor the ATF

temperature as follows:

NOTE:
The ATF level will be significantly affected by the ATF temperature as shown. Therefore monitor the ATF
temperature data using the CONSULT-II.

a.

Connect CONSULT-II to data link connector.

b.

Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.

c.

Read out the value of “ATF TEMP 1”.

6.

Re-check the ATF level at ATF temperatures of approximately
65

°

C (149

°

F) using the “HOT” range on the ATF level gauge as

shown. The HOT range is between 50

°

 - 80

°

 C (122

°

 - 176

°

 F).

CAUTION:

●

When wiping the ATF from the ATF level gauge, always
use lint-free paper, not a cloth.

●

To check the ATF level, insert the ATF level gauge until
the cap contacts the top of the charging pipe, with the
gauge reversed from the normal inserted position as
shown.

7.

Check the ATF condition.

●

If the ATF is very dark or has some burned smell, there may
be an internal problem with the transmission. Refer to 

AT-181,

"TROUBLE DIAGNOSIS FOR SYMPTOMS"

 . Flush the trans-

mission cooling system after repairing the transmission.

●

If the ATF contains frictional material (clutches, bands, etc.),
replace the radiator and flush the transmission cooler lines
using cleaning solvent and compressed air after repairing the
transmission.

8.

Install the ATF level gauge in the charging pipe.

9.

Tighten the ATF level gauge bolt to specification.

Changing the Automatic Transmission Fluid (ATF)

ELS001OR

1.

Drive the vehicle to warm up the ATF to approximately 80

°

 C (176

°

 F).

2.

Stop the engine.

3.

Remove the ATF level gauge.

4.

Drain the ATF from the drain plug hole and then install the drain
plug with a new gasket. Refill the transmission with new ATF.
Always refill with the same volume as the drained ATF. Use the
ATF level gauge to check the ATF level as shown. Add ATF as
necessary.

●

To flush out the old ATF from the transmission oil coolers, pour new ATF into the charging pipe with the
engine idling and at the same time drain the old ATF from the auxiliary transmission oil cooler hose
return line.

●

When the color of the ATF coming out of the auxiliary transmission oil cooler hose return line is about
the same as the color of the new ATF, flushing out the old ATF is complete. The amount of new ATF
used for flushing should be 30% to 50% of the specified capacity.

CAUTION:

●

Use only Genuine NISSAN ATF and do not mix with other fluids.

●

Using automatic transmission fluid other than Genuine NISSAN ATF will cause deterioration in
driveability and automatic transmission durability, and may damage the automatic transmis-
sion, which is not covered by the warranty.

●

When filling the transmission with ATF, do not spill the ATF on any heat generating parts such
as the exhaust manifold.

●

Do not reuse the drain plug gasket.

5.

Drive the vehicle to warm up the ATF to approximately 80

°

 C (176

°

 F).

6.

Install the ATF level gauge and tighten the ATF level gauge bolt to specification.

7.

Check the fluid level and condition. If the ATF is still dirty, repeat
steps 2 through 6.

8.

Install the ATF level gauge in the charging pipe and install the ATF level gauge bolt.

9.

Tighten the ATF level gauge bolt to specification.
