Changing A/T FluidNCS001AT
1. Warm up ATF.
2. Stop engine.
3. Loosen the level gauge bolt.
4. 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, at the same time drain the old ATF
from the radiator cooler hose return side.

When the color of the ATF coming out is almost same as the
color of the new ATF, the replacement is complete. The
amount of new ATF to use should be 30 to 50% of the stipu-
lated amount.
CAUTION:

Use only Genuine NISSAN Matic J ATF. Do not mix with other ATF.

Using ATF other than Genuine NISSAN 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 ATF, take care not to scatter heat generating parts such as exhaust.

Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to AT- 1 3 , "
Checking A/T Fluid" . If ATF is still dirty, repeat step 2.
through 5.
7. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
8. Tighten the level gauge bolt. ATF: Genuine NISSAN Matic J ATF
Fluid capacity: 10.3 (10-7/8 US qt, 9-1/8 lmp qt)
Drain plug: : 34 N·m (3.5 kg-m, 25 ft-lb)
Level gauge bolt: : 5.1 N·m (0.52 kg-m, 45 in-lb)

A/T FLUID
Revision: 2006 December 2006 FX35/FX45
CAUTION:

When wiping away the A/T fluid level gauge, always use lint-free paper, not a cloth one.

To check A/T fluid level, insert the A/T fluid level gauge
until the cap contacts the end of the A/T fluid charging
pipe, with the A/T fluid level gauge reversed from the nor-
mal attachment conditions as shown.
8. Check A/T fluid condition.

If ATF is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-14,
"RADIATOR" (for VQ35DE) or CO-41, "RADIATOR" (for
VK45DE) and AT- 1 5 , "
A/T Fluid Cooler Cleaning" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
10. Tighten level gauge bolt.
Level gauge bolt: : 5.1 N·m (0.52 kg-m, 45 in-lb)

INSTALLATION
Install liquid tank, and then install liquid tank bracket on condenser.
CAUTION:

Make sure liquid tank bracket is securely installed at protru-
sion of condenser. (Make sure liquid tank bracket does not
move to a position below center of liquid tank.)
