°

F) using “HOT” range on A/

T fluid level gauge.

CAUTION:

• When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.
• Firmly fix the A/T fluid level gauge to the A/T fluid charging pipe using a stopper attached.

Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained ATF.
• To replace the ATF, pour in new ATF at the A/T fluid charging pipe with the engine idling and at the same

time drain the old ATF from the radiator cooler hose return side.

• When the color of the ATF coming out is about the same as the color of the new ATF, the replacement is

complete. The amount of new ATF to use should be 30 to 50% increase of the stipulated amount.

T durability, and may damage the A/T, which is not covered by the NISSAN new vehicle limited
warranty.

• When filling ATF, be careful not to scatter heat generating parts such as exhaust.
• Do not reuse drain plug gasket.

4.

Run engine at idle speed for 5 minutes.

5.

Check A/T fluid level and condition. Refer to 

MA-20, "A/T FLUID : Inspection"

. If ATF is still dirty, repeat

step 2. through 5.

6.

Install the removed A/T fluid level gauge into A/T fluid charging pipe.
