< PRECAUTION >

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-16, "For North America"

.

• 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 pre-

vent 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 interfere

with the operation of the transmission.

• Place disassembled parts in order for easier and proper assembly.

• All parts should be carefully cleaned 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.

• Clean or replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to 

TM-

152, "Service Notice or Precaution"

.

• After overhaul, refill the transmission 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

TM-157, "Changing the A/T Fluid (ATF)"

, 

TM-155, "Checking the A/T Fluid (ATF)"

.

Service Notice or Precaution

INFOID:0000000005258168

TM-36,

"CONSULT-III Function (TRANSMISSION)"

 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 on 

TM-34, "OBD-II Diagnostic Trouble Code (DTC)"

 to complete the

repair and avoid unnecessary blinking of the MIL.

 For details of OBD-II, refer to

A/T Fluid Cooler Cleaning

INFOID:0000000005258173

Whenever an 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. Position a drain pan under the A/T inlet and outlet fluid cooler tube to cooler hose connection.
2. Put a different color matching mark on each cooler tube to cooler hose connection to aid in assembly.

CAUTION:

Use paint to make the matching mark. Do not damage the tubes or hose.

3. Disconnect the fluid cooler inlet and outlet rubber hoses from the

steel cooler tubes.

NOTE:

Replace the cooler hoses if rubber material from the hose

remains on the tube fitting.

4. Drain any A/T fluid from the cooler hose.

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 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 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 tip of the air gun and the cooler out-

let 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 fluid.
