A/T FLUID : Changing the A/T Fluid (ATF)

INFOID:0000000005403152

CAUTION:

If using the vehicle for towing, the A/T fluid 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.
