A/T FLUID
Revision: 2007 April2007 M35/M45
A/T FLUIDPFP:KLE40
Changing A/T FluidNCS001JI
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 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.
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

A/T FLUID
Revision: 2007 April2007 M35/M45
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 A/T fluid 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 engine), CO-43, "RADIATOR"
(for VK45DE engine) and AT- 1 4 , "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.
A/T Fluid Cooler CleaningNCS001JK
Whenever an A/T is 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 ATF. In either case, mal-
function of the newly serviced A/T may result.
Debris, if present, may build up as ATF 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 an oil pan under the A/T inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the A/T fluid cooler inlet and outlet rubber hoses
from the steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4. Allow any ATF that remains in the cooler hoses to drain into the
oil pan.Level gauge bolt

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.)

Replace O-rings of liquid tank pipe (inside pipe and outside
pipe) with new ones, and then apply compressor oil to it
when installing it.

When recharging refrigerant, check for leaks.
