Changing A/T FluidECS00FWD
1. Warm up ATF.
2. Stop engine.
3. Loosen level gauge bolt.
4. Remove A/T fluid level gauge.
5. Remove drain plug and drain ATF from drain hole.
6. Install drain plug gasket and drain plug to oil pan.
CAUTION:
Do not reuse drain plug gasket.
7. Tighten drain plug to the specified torque. Refer toAT-218,
"COMPONENTS".
8. Refill with new ATF. Always refill same volume with drained ATF.
lTo replace the ATF, pour in new ATF at A/T fluid charging pipe
with the engine idling and at the same time drain the old ATF
from A/T fluid cooler hose return side.
lWhen 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 specified amount.
CAUTION:
lUse only Genuine NISSAN ATF Matic Fluid J. Do not mix with other ATF.
lUsing ATF other than Genuine NISSAN ATF Matic Fluid J will cause deterioration in driveability
and A/T durability, and may damage the A/T, which is not covered by the NISSAN new vehicle
warranty.
lWhen filling ATF, take care not to spillover heat generating parts such as exhaust.
9. Run engine at idle speed for 5 minutes.
10. Check A/T fluid level and condition. Refer toAT-12, "
Checking A/T Fluid". If ATF is still dirty, repeat step 2
through 9.
11. Install the removed A/T fluid level gauge into A/T fluid charging pipe.
12. Tighten level gauge bolt to the specified torque. Refer toAT- 2 4 7 , "

A/T FLUID
Checking A/T Fluid
ECS00FWE
1. Warm up engine.
2. Check for A/T fluid leakage.
3. Loosen level gauge bolt.
4. 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.
c. Check A/T fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away A/T fluid level gauge, always use lint-
free paper, not a cloth one.
e. Reinsert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
To check A/T fluid level, insert A/T fluid level gauge until the cap contacts the end of A/T fluid
charging pipe, with A/T fluid level gauge reversed from the normal attachment conditions.
f. Remove A/T fluid level gauge and note reading. If reading is at low side of range, add ATF to A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. 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-II.
a. Connect CONSULT-II to data link connector. Refer toAT-79, "
CONSULT-II SETTING PROCEDURE".
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Readthevalueof“ATFTEMP1”.
7. Recheck A/T fluid level at A/T fluid temperatures of approximately 65°C(149°F)using“HOT”rangeonA/
T fluid level gauge.

TROUBLE DIAGNOSIS
How to Perform Trouble Diagnosis for Quick and Accurate Repair
ECS00FWX
INTRODUCTION
The TCM receives a signal from the vehicle speed sensor, accelera-
tor pedal position sensor or PNP switch and provides shift control or
lock-up control via A/T solenoid valves.
Input and output signals must always be correct and stable in the
operation of the A/T system. The A/T system must be in good oper-
ating condition and be free of valve seizure, solenoid valve malfunc-
tion, etc.
It is much more difficult to diagnose a error that occurs intermittently
rather than continuously. Most intermittent errors are caused by poor
electric connections or improper wiring. In this case, careful check-
ing of suspected circuits may help prevent the replacement of good
parts.
A visual check only may not find the cause of the errors. A road test
with CONSULT-II or a circuit tester connected should be performed.
Follow theAT-37, "
WORK FLOW".
Before undertaking actual checks, take a few minutes to talk with a
customer who approaches with a driveability complaint. The cus-
tomer can supply good information about such errors, especially
intermittent ones. Find out what symptoms are present and under
what conditions they occur. A “DIAGNOSTIC WORKSFEET” as
shown on the example (Refer toAT-38
) should be used.
Start your diagnosis by looking for “conventional” errors first. This will
help troubleshoot driveability errors on an electronically controlled
engine vehicle.
Also check related Service bulletins.

A/T Fluid Condition Check
Inspect the A/T fluid condition.
STALL TEST
Stall Test Procedure
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/
Tfluidtemperatureis50to80°C(122to176°F). Inspect the
amount of ATF. Replenish if necessary.
3. Securely engage the parking brake so that the tires do not turn.
4. Engine start, apply foot brake, and place selector lever in “D”
position.
5. While holding down the foot brake, gradually press down the
accelerator pedal.
6. Quickly read off the stall speed, then quickly remove your foot
from the accelerator pedal.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
7. Move selector lever to the “N” position.
8. Cool down the ATF.
