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 automatic transmission's 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 cooler cleaner only with adequate ventilation.

Avoid contact with eyes and skin.

Do not 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 (70 to 130 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 AT- 1 7 , "

A/T FLUID COOLER 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 fluid cooler is not serviceable. The A/T fluid
cooler/radiator must be replaced and the inspection procedure is
ended. Refer to CO-14, "
RADIATOR" and CO-17, "RADIATOR
(ALUMINUM TYPE)" (for VQ35DE), CO-41, "RADIATOR" and
CO-45, "
RADIATOR (ALUMINUM TYPE)" (for VK45DE).
A/T FLUID COOLER FINAL INSPECTION
After performing all procedures, ensure that all remaining oil is cleaned from all components.

6. Start the engine, then measure the line pressure at both idle and
the stall speed.
CAUTION:

Keep the brake pedal pressed all the way down during
measurement.

When measuring the line pressure at the stall speed,
refer to AT- 5 2 , "
STALL TEST" .
7. After the measurements are complete, install the oil pressure detection plug and tighten to the specified torque.
CAUTION:

Do not reuse the O-ring.

Apply ATF to the O-ring.

Judgement Possible cause
Idle speed Low for all positions
(“P”, “R”, “N”, “D”,

For example

Oil pump wear

Pressure regulator valve or plug sticking or spring fatigue

Oil strainer
oil pump
pressure regulator valve passage oil leak

Engine idle speed too low
Only low for a spe-
cific position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
High Possible causes include a sensor malfunction or malfunction in the line pressure adjustment func-
tion.
For example

Accelerator pedal position signal malfunction

ATF temperature sensor malfunction

Line pressure solenoid malfunction (sticking in OFF state, filter clog, cut line)

Pressure regulator valve or plug sticking

TROUBLE DIAGNOSIS
Revision: 2005 July 2005 FX
ROAD TEST
Description

The road test checks overall performance of the A/T and analyzes possible malfunction causes.

The road test is carried out in the following three stages.
1. Check before engine is started. Refer to AT- 5 6
.
2. Check at idle. Refer to AT- 5 7
.
3. Cruise test

Inspect all the items from Part 1 to Part 3. Refer to AT- 5 8 , AT- 6 0 , AT- 6 1 .

Before beginning the road test, check the test procedure and inspection items.

Test all inspection items until the symptom is uncovered. Diagnose NG items when all road tests are com-
plete.
Check Before Engine Is StartedACS002LZ
1. CHECK A/T CHECK INDICATOR LAMP
1. Park vehicle on level surface.
2. Move selector lever to “P” position.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON.
Does A/T CHECK indicator lamp light up for about 2 seconds?
YES >> GO TO 2.
NO >> Stop the road test and go to AT- 1 9 3 , "
A/T CHECK Indicator Lamp Does Not Come On" .
2. CHECK A/T CHECK INDICATOR LAMP
Does A/T CHECK indicator lamp flash for about 8 seconds?
YES >> For TCM fail-safe mode, perform self-diagnostics and record all NG items on the AT- 4 7 , "DIAG-
NOSTIC WORKSHEET" . Refer to AT- 9 3 , "SELF-DIAGNOSTIC RESULT MODE" , AT- 1 0 3 , "Diag-
nostic Procedure without CONSULT-II" .
NO >> 1. Turn ignition switch OFF.
2. Perform self-diagnostics and record all NG items on the AT- 4 7 , "
DIAGNOSTIC WORKSHEET"
. Refer to AT- 9 3 , "SELF-DIAGNOSTIC RESULT MODE" , AT- 1 0 3 , "Diagnostic Procedure with-
out CONSULT-II" .
3. Go to AT- 5 7 , "
Check at Idle" .
Stall speed Oil pressure does
not rise higher than
the oil pressure for
idle. Possible causes include a sensor malfunction or malfunction in the pressure adjustment function.
For example

Accelerator pedal position signal malfunction

TCM breakdown

Line pressure solenoid malfunction (shorting, sticking in ON state)

Pressure regulator valve or plug sticking

Pilot valve sticking or pilot filter clogged
The pressure rises,
but does not enter
the standard posi-
tion. Possible causes include malfunctions in the pressure supply system and malfunction in the pres-
sure adjustment function.
For example

Accelerator pedal position signal malfunction

Line pressure solenoid malfunction (sticking, filter clog)

Pressure regulator valve or plug sticking

Pilot valve sticking or pilot filter clogged
Only low for a spe-
cific position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
