PRECAUTIONS
Revision: 2006 July 2007 FX35/FX45
Precautions NCS001AP

Before connecting or disconnecting the A/T assembly har-
ness connector, turn ignition switch OFF and disconnect
the battery cable from the negative terminal. Because bat-
tery voltage is applied to TCM even if ignition switch is
turned OFF.

After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
If the repair is completed the DTC should not be displayed
in the “DTC Confirmation Procedure”.

Always use the specified brand of ATF. Refer to MA-12, "Fluids and Lubricants" .

Use lint-free paper not cloth rags during work.

After replacing the ATF, dispose of the waste oil using the methods prescribed by law, ordinance, etc.

Before proceeding with disassembly, thoroughly clean the outside of the transmission. It is important to
prevent the internal parts from becoming contaminated by dirt or other foreign matter.

Disassembly should be done in a clean work area.

Use lint-free paper or towels for wiping parts clean. Common shop rags can leave fibers that could inter-
fere with the operation of the transmission.

Place disassembled parts in order for easier and proper assembly.

All parts should be carefully cleansed with a general purpose, non-flammable solvent before inspection or
reassembly.

Gaskets, seals and O-rings should be replaced any time the transmission is disassembled.

It is very important to perform functional tests whenever they are indicated.

The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.

Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.

Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.

Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

After overhaul, refill the transmission with new ATF.

When the A/T drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque con-
verter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to AT- 1 2 , "
Changing A/T Fluid" , AT- 1 3 , "Checking A/T Fluid" .

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% 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
Fluid capacity: 10.3 (10-7/8 US qt, 9-1/8 lmp qt)

9. Check foreign materials in oil pan to help determine causes of malfunction. If the ATF is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.

If frictional material is detected, perform A/T fluid cooler
cleaning. Refer to AT- 1 5 , "
A/T Fluid Cooler Cleaning" .
10. Remove magnets from oil pan.
