• 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.
• Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to
Refer to .
• After overhaul, refill the A/T with new ATF.
• When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid 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
MA-22, "
Changing A/T Fluid", MA-22, "Checking A/T Fluid".
Service Notice or PrecautionINFOID:0000000001703155
ATF COOLER SERVICE
If A/T fluid contains frictional material (clutches, bands, etc.), or if an A/T is repaired, overhauled, or replaced,
inspect and clean the A/T oil cooler mounted in the radiator or replace the radiator. Flush cooler lines using
cleaning solvent and compressed air after repair. Check Service Bulletins for latest A/T oil cooler cleaning pro-
cedure. For radiator replacement, refer to Refer to CO-11
.
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:
• External leaks in the hub weld area.
• Converter hub is scored or damaged.
• Converter pilot is broken, damaged or fits poorly into crankshaft.
• Steel particles are found after flushing the cooler and cooler lines.
• Pump is damaged or steel particles are found in the converter.
• Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)
• Converter is contaminated with engine coolant containing antifreeze.
• Internal malfunction of stator roller clutch.
• Heavy clutch debris due to overheating (blue converter).
• Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:
• The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.
• The threads in one or more of the converter bolt holes are damaged.
• A/T malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch plate lin-
ing material in unit and inside the fluid filter.
• Vehicle has been exposed to high mileage (only). The exception may be where the torque converter clutch
dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic, such as
taxi, delivery or police use.
OBD-II SELF-DIAGNOSIS
• A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through
the blinking pattern of the OD OFF indicator lamp or the malfunction indicator lamp (MIL). Refer to the table
on AT-78, "
Diagnosis Procedure without CONSULT-III" for the indicator used to display each self-diagnostic
result.
• The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure “HOW TO ERASE DTC” on AT-36, "
OBD-II Diagnostic Trouble Code
(DTC)" to complete the repair and avoid unnecessary blinking of the MIL.
• The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when the
OD OFF indicator lamp does not indicate any malfunctions.
-PNP switch
- A/T 1st, 2nd, 3rd, or 4th gear function
*: For details of OBD-II, refer to AT- 3 6
.
•Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector.
For description and how to disconnect, refer to PG-65
.

A/T FLUID
5. Run engine at idle speed for 5 minutes.
6. Check A/T fluid level and condition. Refer to MA-22, "
Checking A/T Fluid".
A/T Fluid Cooler CleaningINFOID:0000000001703160
Whenever the A/T is repaired, overhauled, or 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 A/T fluid. In either case,
malfunction of the newly serviced A/T may result.
Debris, if present, may build up as A/T fluid 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. Identify the A/T inlet and outlet fluid cooler hoses.
2. Position an oil pan under the A/T 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 A/T fluid 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 the
Transmission 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 A/T fluid flows out of the cooler inlet hose for 5 seconds.
7. Insert the tip of an air gun into the end of the cooler outlet hose.
8. Wrap a shop rag around the air gun tip and end of cooler outlet
hose.
9. Blow compressed air regulated to 5 - 9 kg/cm
2 (70 - 130 psi) through the cooler outlet hose for 10 seconds
to force out any remaining A/T fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connect the A/T fluid cooler steel lines to the A/T.
12. Remove the banjo bolts.Fluid grade and capacity: Refer to MA-10

REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-23, "
Removal and Installation".
3. Drain the A/T fluid. Refer to AT- 1 5
.
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of
malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
•If ATF contains frictional material (clutch, bands, etc.),
replace radiator and flush cooler line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
11.
