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 breathe 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.

b.

If one or more pieces of debris are found that are over 1 mm
(0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the A/T fluid cooler is not serviceable. The A/T
fluid cooler/radiator must be replaced and the inspection proce-
dure is ended. Refer to

CO-13, "Removal and Installation"

.

STALL TEST

Inspection and Judgment

INFOID:0000000008285893

INSPECTION

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). Inspect the amount of ATF. Replenish if necessary.

3.

Securely engage the parking brake so that the tires do not turn.

4.

Start the engine, apply foot brake, and place selector lever in “D” position.

5.

Gradually press down the accelerator pedal while holding down the foot brake.

6.

Quickly read off the stall speed, and then quickly release the accelerator pedal.

CAUTION:

Never hold down the accelerator pedal for more than 5 seconds during this test.

7.

Shift the selector lever to “N” position.

8.

Cool down the ATF.

CAUTION:

Run the engine at idle for at least 1 minute.

9.

Repeat steps 5 through 8 with selector lever in “R” position.

A/T POSITION

Inspection and Adjustment

INFOID:0000000008285894

INSPECTION

1.

Place selector lever in “P” position, and turn ignition switch ON (engine stop).

2.

Check that selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
check that selector lever can be shifted from “P” position only when brake pedal is depressed.

3.

Shift the selector lever and check for excessive effort, sticking, noise or rattle.

4.

Confirm that the selector lever stops at each position by feeling the engagement when it is moved through
all the positions. Check whether or not the actual position the selector lever matches the position shown
by the shift position indicator and the A/T body.

5.

The method of operating the lever to individual positions cor-
rectly is shown in the figure.

6.

When selector button is pressed in “P”, “R”, or “N” position with-
out applying forward/backward force to selector lever, check but-
ton operation for sticking.

7.

Confirm that the back-up lamps illuminate only when lever is
placed in the “R” position. Confirm that the back-up lamps do not
illuminate when selector lever is pushed against “R” position in
the “P” or “N” position.

8.

Confirm that the engine can only be started with the selector
lever in the “P” and “N” positions. (With selector lever in the “P”
position, engine can be started even when selector lever is
moved forward and backward.)

9.

Make sure that A/T is locked completely in “P” position.

10. DS mode must be indicated on the combination meter when the selector lever is shifted to the manual

shift gate. When the selector lever is shifted to the “+” or “

” side in the DS mode, manual mode should be

indicated on the combination meter.
In addition, a set shift position must be changed when the selector lever is shifted to the “+” or “

” side in

the manual mode. (Only while driving.)

ADJUSTMENT

1.

Loosen nut (

).

2.

Place manual lever and selector lever in “P” position.

3.

While pressing lower lever (A) toward rear of vehicle (in “P” posi-
tion direction), tighten nut to specified torque. Refer to

TM-182,

"Removal and Installation"

.

CAUTION:

Be careful not to touch the control rod while pressing lower
lever of A/T shift selector assembly.
NOTE:
Press lower lever of A/T shift selector assembly with a force of
approximately 1 kg (9.8 N).

INSPECTION AFTER REMOVAL

Check foreign materials in oil pan to help determine causes of mal-
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up.
Varnish can cause valves, servo, and clutches to stick and can
inhibit pump pressure.
If frictional material is detected, replace radiator after repair of

A/T. Refer to

CO-13, "Removal and Installation"

.

INSPECTION AFTER INSTALLATION

Check A/T fluid leakage. Refer to

TM-173, "Inspection"

.
