A/T Fluid Cooler Cleaning INFOID:0000000004305297
Whenever the 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 becom e trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can bloc k 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 c ooler 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. Identify the A/T inlet and outlet fluid cooler hoses.
2. Position an oil pan under the A/T inlet and outlet fluid cooler hoses.
3. Disconnect the A/T fluid cooler inlet and outlet rubber hoses from the steel cooler tubes or bypass valve.
NOTE:
Replace the cooler hoses if rubber material from the hose
remains on the tube fitting.
4. Allow any A/T fluid 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 breathe 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 A/T fluid flows out of t he 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 end of cooler outlet hose.
9. Blow compressed air regulated to 5 - 9 kg/cm 2
(71 - 128 psi) through the cooler outlet hose for 10 seconds
to force out any remaining A/T fluid.
10. Repeat steps 5 through 9 three additional times.
11. Position an oil pan under the banjo bolts that connec t the A/T fluid cooler steel lines to the A/T.
12. Remove the banjo bolts. Fluid grade and capacity: Refer to
MA-14 .

13. Flush each steel line from the cooler side back to
ward the A/T by spraying Transmission Cooler Cleaner
in a continuous stream for 5 seconds.
14. Blow compressed air regulated to 5 - 9 kg/cm 2
(71 - 128 psi) through each steel line from the cooler side
back toward the A/T for 10 seconds to force out any remaining A/T fluid.
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 "A/T FLUID COOL ER DIAGNOSIS PROCEDURE".
A/T FLUID COOLER DIAGNOSIS PROCEDURE NOTE:
Insufficient cleaning of the cooler inlet hose exte rior 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.
• Do not 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 A/T fluid flows out of t he 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 - 9 kg/cm 2
(71 - 128 psi)
through the cooler outlet hose to force any remaining A/T fluid
into the coffee filter.
9. Remove the coffee filter from the end of the cooler inlet hose.
10. Perform "A/T FLUID COOL ER INSPECTION PROCEDURE".

DTC P0744 A/T TCC S/V FUNCTION (LOCK-UP)
Description INFOID:0000000004305397
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosis malfunction.
• This malfunction is detected when the A/T does not shif t into fourth gear position or the torque converter
clutch does not lock-up as instructed by the TCM. This is not caused by electrical malfunction (circuits open
or shorted) but by mechanical malfunction such as c ontrol valve sticking, improper solenoid valve operation,
malfunctioning oil pump or torque converter clutch, etc.
CONSULT-III Reference Val ue in Data Monitor Mode INFOID:0000000004305398
Remarks: Specification data are reference values.
On Board Diagnosis Logic INFOID:0000000004305399
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0744 A/T TCC S/V FNCTN” wi th CONSULT-III is detected when A/T cannot per-
form lock-up even if electrical circuit is good.
• This diagnosis monitors actual gear position by checki ng the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is much lower than the pos ition (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach t he specified value, TCM judges this diagnosis malfunc-
tion.
This malfunction will be caused when shift solenoid valve B is stuck closed.
• Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve B stu ck closed: 1, 2, 2 and 1* positions to each gear position
above
*: “P0744 A/T TCC S/V FNCTN” is detected.
Possible Cause INFOID:0000000004305400
• Line pressure solenoid valve
• Torque converter clutch solenoid valve
• Each clutch
• Hydraulic control circuit
DTC Confirmation Procedure INFOID:0000000004305401
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine and select “DATA MONITOR” m ode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Make sure that output voltage of A/T fluid temperature sensor is within the range below. FLUID TEMP SE: 0.4 - 1.5 V
If out of range, drive vehicle to decrease voltage (warm up the fluid) or stop engine to increase voltage
(cool down the fluid).
4. Select “TCC S/V FNCTN P0744” of “DTC & SR T CONFIRMATION” mode for “TRANSMISSION” with
CONSULT-III and touch “START”.

•
Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly or
not. CVT-49, " TCM Terminal and Reference Value " .
• After performing each TROUBL E DIAGNOSIS, perform “DTC
Confirmation Procedure”.
If the repair is completed the DTC should not be displayed in
the “DTC Confirmation Procedure”.
• Always use the specified br and of CVT fluid. Refer to MA-14, " Flu-
ids and Lubricants " .
• Use lint-free paper, not cloth rags, during work.
• After replacing the CVT fluid, dispose of the waste oil using the methods prescribed by law, ordinance, etc.
Service Notice or Precaution INFOID:0000000004666859
CVT FLUID COOLER SERVICE If CVT fluid contains friction material (clutches, brakes , etc.), or if an CVT is replaced, inspect and clean the
CVT fluid cooler mounted in the radiator or replace t he radiator. Flush cooler lines using cleaning solvent and
compressed air after repair. For CVT fluid cooler cleaning procedure, refer to CVT-18, " CVT Fluid Cooler
Cleaning " . For radiator replacement, refer to
CO-38 .
OBD-II SELF-DIAGNOSIS • CVT self-diagnosis is performed by the TCM in comb ination with the ECM. The results can be read through
the blinking pattern of the malfunction indi cator lamp (MIL). Refer to the table on CVT-51, " CONSULT-III
Function (TRANSMISSION) " for the indicator used to display each self-diagnostic result.
• The self-diagnostic results indicated by the MIL ar e automatically stored in both the ECM and TCM memo-
ries.
Always perform the procedure on CVT-30, " OBD-II Diagnostic Trouble Code (DTC) " to complete the
repair and avoid unnecessary blinking of the MIL.
For details of OBD-II, refer to EC-541, " Introduction " .
• Certain systems and components, especially those re lated to OBD, may use the new style slide-lock-
ing type harness connector. For descripti on and how to disconnect, refer to PG-64 . MEF040DA
