PRECAUTIONS
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-9, "
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 out side of the transmission. It is important to pre-
vent the internal parts from becoming cont aminated 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 interfere
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 s lide 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 t he 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- 11 , "
Changing A/T Fluid", AT- 11 , "Checking A/T Fluid".
Service Notice or PrecautionINFOID:0000000001327125
ATF COOLER SERVICE
If ATF contains frictional material (clutches, bands, etc. ), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T fluid cooler mounted in the radiat or or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. For A/T fluid cooler cleaning procedure, refer to AT-13, "
A/T
Fluid Cooler Cleaning". For radiator replacement, refer to CO-13 (for VQ35DE), CO-40 (for VK45DE).
OBD-II SELF-DIAGNOSIS
 A/T self-diagnosis is performed by the TCM in comb ination with the ECM. The results can be read through
the blinking pattern of the A/T CHECK indicator or the malfunction indicator lamp (MIL). Refer to the table on
AT-84, "
CONSULT-III Function (TRANSMISSION)" for the indicator used to display each self-diagnostic
result.
 The self-diagnostic results indicated by the MIL ar e automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure on AT-38, "
OBD-II Diagnostic Trouble Code (DTC)" to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-54
(for VQ35DE) or EC-632 (for VK45DE).
 Certain systems and components, especially those re lated to OBD, may use the new style slide-lock-
ing type harness connector. For descrip tion and how to disconnect, refer to PG-68
.

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 chargingpipe 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 AT F 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- 11 , "
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.
Checking A/T FluidINFOID:0000000001327129
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Loosen the level gauge bolt.
4. Before driving, A/T fluid level can be checked at A/T fluid tem- peratures of 30 to 50 °C (86 to 122 °F) using “COLD” range on A/
T fluid level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi- tion. Leave selector lever in “P” position.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free paper.

A/T Fluid Cooler CleaningINFOID:0000000001327130
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 becom e trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can bl ock or restrict the flow of ATF. In either case, mal-
function of the newly se rviced 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's inlet and outlet cooler hoses.
2. Identify the inlet and outlet A/T 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.
5. Insert the extension adapter hose of a can of Transmission Cooler Cleaner (Nissan P/N 999MP-AM006) into the cooler out-
let hose.
CAUTION:
 Wear safety glasses and rubber gloves when spraying theTransmission Cooler Cleaner.
 Spray Transmission Cooler Cleaner only with adequate
ventilation.
 Avoid contact with eyes and skin.
 Do not breath vapors or spray mist.
6. Hold the hose and can as high as possible and spray Transmis- sion Cooler Cleaner in a continuous stream into the cooler outlet
hose until ATF flows out of the cooler inlet hose for 5 seconds.Level gauge bolt:

STALL TEST
Stall Test Procedure
1. Inspect the amount of engine oil. Replenish the engine oil if necessary.
2. Drive for about 10 minutes to warm up the vehicle so that the A/T fluid temperature is 50 to 80 °C (122 to 176 °F). Check the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Start engine, apply foot brake, and place selector lever in “D” position.
5. While holding down the foot brake, gradually press down the accelerator pedal.
6. Quickly read off the stall speed, then quickly remove your foot from the accelerator pedal.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
7. Move the selector lever to the “N” position.
8. Cool down the ATF. CAUTION:
Run the engine at idle for at least 1 minute.
