Adjustment

INFOID:0000000005250343

CAUTION:

• Use only Genuine NISSAN Matic S ATF. Never mix with other ATF.
• Using ATF other than Genuine NISSAN Matic S ATF will cause deterioration in driveability and A/T

durability, and may damage the A/T, which is not covered by the INFINITI new vehicle limited war-
ranty.

• When filling ATF, be careful not to scatter heat generating parts such as exhaust.
• Always maintain the ATF temperature within between 35

°

C (95

°

F) and 45

°

C (113

°

F) while checking

with CONSULT-III when the ATF level adjustment is performed.

A/T FLUID COOLER

Cleaning

INFOID:0000000005250344

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.

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 by-pass 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 the

Transmission Cooler Cleaner.

• Spray Transmission Cooler Cleaner only with adequate

ventilation.

• Avoid contact with eyes and skin.
• Never 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.

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 of the cooler outlet
hose.

9.

Blow compressed air regulated to 5 to 9 kg/cm

2

 (71 to 128 psi)

through the cooler outlet hose for 10 seconds to force out any
remaining ATF.

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.

13. Flush each steel line from the cooler side back toward the A/T

by spraying Transmission Cooler Cleaner in a continuous stream for 5 seconds.

14. Blow compressed air regulated to 5 to 9 kg/cm

2

 (71 to 128 psi) through each steel line from the cooler

side back toward the A/T for 10 seconds to force out any remaining ATF.

15. Ensure all debris is removed from the steel cooler lines.

16. Ensure all debris is removed from the banjo bolts and fittings.

17. Perform “DIAGNOSIS PROCEDURE”.

A/T FLUID COOLER

DIAGNOSIS PROCEDURE

NOTE:
Insufficient cleaning of the cooler inlet hose exterior may lead to inaccurate debris identification.

1.

Position an oil pan under the A/T inlet and outlet cooler hoses.

2.

Clean the exterior and tip of the cooler inlet hose.

3.

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.
• Never breath vapors or spray mist.

4.

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.

5.

Tie a common white, basket-type coffee filter to the end of the
cooler inlet hose.

6.

Insert the tip of an air gun into the end of the cooler outlet hose.

7.

Wrap a shop rag around the air gun tip and end of cooler outlet
hose.

8.

Blow compressed air regulated to 5 to 9 kg/cm

2

 (71 to 128 psi)

through the cooler outlet hose to force any remaining ATF into
the coffee filter.

9.

Remove the coffee filter from the end of the cooler inlet hose.

10. Perform “INSPECTION PROCEDURE”.

INSPECTION PROCEDURE

1.

Inspect the coffee filter for debris.

a.

If small metal debris less than 1 mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T fluid cooler/radiator can be re-used and
the procedure is ended.
