VALUES ON DIAGNOSIS TOOL
NOTE:
1. The CONSULT-III electrically displays shift timi
ng and lock-up timing (that is, operation timing of each
solenoid).
Check for time difference between actual shift timi ng and the CONSULT-III display. If the difference is
noticeable, mechanical parts (except solenoids, sens ors, etc.) may be malfunctioning. Check mechanical
parts in accordance with the specified diagnostic procedures.
2. Shift schedule (that implies gear position) on CONSULT-III may slightly differ from that is described in Ser-
vice Manual. This occurs because of the reasons as per the following:
- Actual shift schedule has more or less tolerance or allowance
- Shift schedule in Service Manual refers to the point where shifting starts
- Gear position on CONSULT-III indicates the point where shifting completes
3. Display of solenoid valves on CONSULT-III changes at t he start of shifting, while gear position is displayed
upon completion of shifting (which is computed by TCM).

CAUTION:
 Use only Genuine NISSAN Matic S ATF. Never mix with other ATF.
 Using ATF other than Genuine NI
SSAN Matic S ATF will cause deteri oration 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 scatte r heat generating parts such as exhaust.
1. Step 1
a. Install the O-ring (315268E000) (A) to the charging pipe (310811EA5A) (B).
2. Step 2
a. Use CONSULT-III to check that the ATF temperature is 40 °C (104 °F) or less.
b. Lift up the vehicle.
c. Remove the drain plug from the oil pan, and then drain the ATF.
d. When the ATF starts to drip, temporarily tighten the drain plug to the oil pan. NOTE:
Never replace drain plug and drain plug gasket with new ones yet.
e. Remove overflow plug from oil pan.
f. Install the charging pipe (A) to the overflow plug hole. CAUTION:
Tighten the charging pipe by hand.
g. Install the bucket pump hose (B) to the charging pipe. CAUTION:
Insert the bucket pump hose all the way to the end of the
charging pipe.
h. Fill approximately 3 liters (3-1/8 US qt, 2-5/8 lmp qt) of the ATF.
i. Remove the bucket pump hose to remove the charging pipe, and then temporarily tighten the overflow plug to the oil pan.
CAUTION:
Quickly perform the procedur e to avoid ATF leakage from
the oil pan.
j. Lift down the vehicle.
k. Start the engine and wait for approximately 3 minutes.
l. Stop the engine.
3. Step 3
a. Repeat “Step 2”.
4. Final Step
a. Use CONSULT-III to check that the ATF temperature is 40 °C (104 °F) or less.
b. Lift up the vehicle.
c. Remove the drain plug from the oil pan, and then drain the ATF.
Recommended fluid and fluid capacity : Refer to TM-296, "General Specification".

l. Make the ATF temperature approximately 40 °C (104 °F).
NOTE:
The ATF level is greatly affected by the temperat ure. Always check the ATF temperature on “ATF TEMP
1” of “Data Monitor” using CONSULT-III.
m. Park vehicle on level surface and set parking brake.
n. Shift the selector lever through each gear pos ition. Leave selector lever in “P” position.
o. Lift up the vehicle when the ATF temperature reaches 40 °C (104 °F), and remove the overflow plug from
the oil pan.
CAUTION:
Perform “Step 4-o” with the engine at idle.
p. When the ATF starts to drip, tighten the overflow plug to the oil pan to the specified torque. Refer to TM-

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 AT F. 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 quickly release the accelerator pedal. CAUTION:
Never hold down the accelerator pedal for more than 5 seconds during this test.
