A/T FLUID LEAKAGE AND A/T FLUID LEVEL CHECK

1.

Warm up engine.

2.

Check for A/T fluid leakage.

3.

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.

Firmly fix the A/T fluid level gauge to the A/T fluid charging
pipe using a stopper attached.

f.

Remove A/T fluid level gauge and note reading. If reading is at
low side of range, add ATF to the A/T fluid charging pipe.

CAUTION:

Do not overfill.

4.

Drive vehicle for approximately 5 minutes in urban areas.

5.

Make the A/T fluid temperature approximately 65

°

C (149

°

F).

NOTE:
A/T fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to
perform operation while checking data with CONSULT-III.

A/T FLUID CONDITION CHECK

Check the A/T fluid condition.

1.

Warm up ATF.

2.

Stop engine.

3.

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 and at the same

time drain the old ATF from the radiator cooler hose return side.

• When the color of the ATF coming out is about the 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 NISSAN new vehicle limited
warranty.

• When filling ATF, be careful not to scatter heat generating parts such as exhaust.
• Do not reuse drain plug gasket.

4.

Run engine at idle speed for 5 minutes.

5.

Check A/T fluid level and condition. Refer to 

TM-214, "Inspection"

. If ATF is still dirty, repeat step 2.

through 5.

6.

Install the removed A/T fluid level gauge into A/T fluid charging pipe.

A/T FLUID COOLER

A/T FLUID COOLER

Cleaning

INFOID:0000000001672234

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.
• 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.

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

 (70 to 130 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

 (70 to 130 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”.
