INFOID:0000000005148723
CAUTION:
If using the vehicle for towing, the A/T fl uid must be replaced as specified. Refer to MA-9, "
Introduc-
tion 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 ATF fluid other than Genuine NISSAN Matic S ATF or Matic J ATF will cause deterioration in driveability and A/T durability, and may damage the A/T, which is not covered by the 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 parts.
• 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. Drain plug : Refer to

A/T FLUID COOLER
A/T FLUID COOLER
A/T Fluid Cooler CleaningINFOID:0000000005148724
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 bloc k 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 c ooler 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 wi th 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 490 - 883 kPa (5 - 9 kg/cm
2, 71 - 128 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 490 - 883 kPa (5 - 9 kg/cm
2, 71 - 128 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 exte rior 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 inle t 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.

REMOVAL AND INSTALLATION
Removal
1. Drain A/T fluid. Refer to TM-150, "Changing the A/T Fluid (ATF)".
2. Remove oil pan clips (1).
3. Remove oil pan (2).
4. Remove oil pan gasket. • : Vehicle front
• : Oil pan bolts
• Drain plug (3)
5. Check foreign materials in oil pan to help determine c ause of malfunction. If the A/T fluid is very dark, has
some burned smell, or contains foreign particles, friction material (clutches, band) may need replacement.
A tacky film that will not wipe clean indicates varnish build up. Varnish can cause valves, servo, and
clutches to stick and can inhibit pump pressure.
CAUTION:
If friction material is detected, flush the transmission cooler after repair. Refer to TM-152, "
A/T
Fluid Cooler Cleaning".
6. Remove magnets from oil pan.
Installation
1. Install the oil pan magnets as shown.
