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 or Matic J will cause

deterioration in driveability. and may damage 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

°

A/T Fluid Cooler Cleaning

INFOID:0000000006244865

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.
