A/T FLUID

5.

Allow the A/T fluid temperature to fall to approximately 65

°

C (149

°

F). Use the CONSULT-III to monitor the

A/T fluid temperature as follows:

NOTE:
The A/T fluid level will be significantly affected by the A/T fluid temperature as shown. Therefore monitor
the A/T fluid temperature data using the CONSULT-III.

a.

Connect CONSULT-III to data link connector.

b.

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

c.

Read out the value of “ATF TEMP 1”.

6.

Re-check the A/T fluid level at A/T fluid temperatures of approxi-
mately 65

°

C (149

°

F) using the “HOT” range on the A/T fluid

level gauge as shown. The HOT range is between 50

°

 - 80

°

 C

(122

°

 - 176

°

 F).

CAUTION:

• When wiping the A/T fluid from the A/T fluid level gauge,

always use lint-free paper, not a cloth.

• To check the A/T fluid level, insert the A/T fluid level

gauge until the cap contacts the top of the A/T fluid charg-
ing pipe, with the gauge reversed from the normal
inserted position as shown.

7.

Check the A/T fluid condition.
• If the A/T fluid is very dark or has some burned smell, there

may be an internal problem with the transmission. Flush the
transmission cooling system after repairing the transmission.

• If the A/T fluid 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 A/T fluid level gauge in the A/T fluid charging pipe.

9.

Tighten the A/T fluid level gauge bolt to specification.

Changing the A/T Fluid (ATF)

INFOID:0000000005274192

CAUTION:

If using the vehicle for towing, the A/T fluid must be replaced as specified. Refer to 

MA-9, "For North

America: Introduction of Periodic Maintenance"

.

1.

Drive the vehicle to warm up the A/T fluid to approximately 80

°

 C (176

°

 F).

2.

Stop the engine.

3.

Remove the A/T fluid level gauge.

4.

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

• To flush out the old A/T fluid from the transmission oil coolers, pour new A/T fluid into the A/T fluid charg-

ing pipe with the engine idling and at the same time drain the old A/T fluid from the auxiliary transmis-
sion oil cooler hose return line.

• When the color of the A/T fluid coming out of the auxiliary transmission oil cooler hose return line is

about the same as the color of the new A/T fluid, flushing out the old A/T fluid is complete. The amount
of new A/T fluid used for flushing should be 30% to 50% increase of the specified capacity.

CAUTION:

• If genuine NISSAN Matic S ATF is not available, Genuine NISSAN Matic J ATF may also be used.

Using automatic transmission fluid other than Genuine NISSAN Matic S ATF or Matic J ATF will
cause deterioration in driveability and automatic transmission durability, and may damage the
automatic transmission, which is not covered by the NISSAN new vehicle limited warranty

• When filling the transmission with A/T fluid, do not spill the A/T fluid on any heat generating

parts such as the exhaust manifold.

• Do not reuse the drain plug gasket.

5.

Install the A/T fluid level gauge and tighten the A/T fluid level gauge bolt to specification.

6.

Drive the vehicle to warm up the A/T fluid to approximately 80

°

 C (176

°

 F).

7.

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

8.

Install the A/T fluid level gauge in the A/T fluid charging pipe and install the A/T fluid level gauge bolt.

9.

Tighten the A/T fluid level gauge bolt to specification.

A/T Fluid Cooler Cleaning

INFOID:0000000005274193

Whenever an A/T is repaired, overhauled, or replaced, the A/T fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block or restrict the flow of A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid enters the cooler inlet. It will be necessary to back flush the cooler
through the cooler outlet in order to flush out any built up debris.

A/T FLUID COOLER CLEANING PROCEDURE

1.

Position a drain pan under the A/T inlet and outlet fluid cooler tube to cooler hose connection.

2.

Put a different color matching mark on each cooler tube to cooler hose connection to aid in assembly.

CAUTION:

Use paint to make the matching mark. Do not damage the tubes or hose.

3.

Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.

4.

Drain any A/T fluid from the cooler hose.

5.

Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.

CAUTION:

• Wear safety glasses and rubber gloves when spraying the

Transmission Cooler Cleaner.

• Spray cooler cleaner only with adequate ventilation.
• Avoid contact with eyes and skin.
• Do not breath vapors or spray mist.

6.

Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until fluid flows out of the cooler inlet hose for 5 seconds.

7.

Insert the tip of an air gun into the end of the cooler outlet hose.

8.

Wrap a shop rag around the tip of the air gun and the cooler out-
let hose.

9.

Blow compressed air regulated to 5 - 9 kg/cm

2

 (70 - 130 psi) through the cooler outlet hose for 10 seconds

to force out any remaining fluid.

10. Repeat steps 5 through 9 three additional times.

11. Position an oil pan under the banjo bolts that connect the fluid cooler tubes to the A/T.

12. Remove the banjo bolts.

13. Flush each steel line from the cooler side back toward the A/T by spraying Transmission Cooler Cleaner

in a continuous stream for 5 seconds.

14. Blow compressed air regulated to 5 - 9 kg/cm

2

 (70 - 130 psi) through each steel line from the cooler side

back toward the A/T for 10 seconds to force out any remaining fluid.

15. Ensure all debris is removed from the steel cooler lines.

16. Ensure all debris is removed from the banjo bolts and fittings.
17. Perform "A/T FLUID COOLER DIAGNOSIS PROCEDURE".

A/T FLUID COOLER DIAGNOSIS PROCEDURE

NOTE:
Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.

1.

Position a drain pan under the A/T inlet and outlet fluid cooler tube to cooler hose connection.

2.

Clean the exterior and tip of the cooler inlet hose.

3.

Put a different color matching mark on each cooler tube to cooler hose connection to aid in assembly.

CAUTION:

Use paint to make the matching mark. Do not damage the tubes or hose.

4.

Disconnect the fluid cooler inlet and outlet rubber hoses from the
steel cooler tubes.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.

5.

Insert the extension adapter hose of a can of Transmission
Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.

CAUTION:

• Wear safety glasses and rubber gloves when spraying the

Transmission Cooler Cleaner.

• Spray cooler cleaner only with adequate ventilation.
• Avoid contact with eyes and skin.
• Do not breath vapors or spray mist.

6.

Hold the hose and can as high as possible and spray Transmis-
sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until fluid flows out of the cooler inlet hose for 5 seconds.

7.

Tie a common white, basket-type coffee filter to the end of the
cooler inlet hose.
