range on ATF level gauge as follows.
a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear position. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove ATF level gauge and wipe clean with lint-free paper.
CAUTION:
When wiping away the fluid level gauge, always use lint-free paper, not a cloth one.
e. Re-insert ATF level gauge into charging pipe as far as it will go.
CAUTION:
To check fluid level, insert the ATF level gauge until the cap contacts the end of the charging pipe,
with the gauge reversed from the normal attachment conditions.
f. Remove ATF level gauge and note reading. If reading is at low side of range, add fluid to the charging
pipe.
CAUTION:
Do not overfill.

NOTE:
Fluid level will be greatly affected by temperature as shown in figure. Therefore, be certain to per-
form operation while checking data with CONSULT-II.
a. Connect CONSULT-II to data link connector.
b. Select “MAIN SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
c. Read out the value of “ATF TEMP 1”.
7. Re-check fluid level at fluid temperatures of approximately 65°C (149°F) using “HOT” range on A/T fluid
level gauge.
CAUTION:

When wiping away the fluid level gauge, always use lint-free paper, not a cloth one.

To check fluid level, insert the A/T fluid level gauge until
the cap contacts the end of the A/T fluid charging pipe,
with the gauge rotated from the normal attachment condi-
tions as shown.
8. Check fluid condition.

If fluid is very dark or smells burned, check operation of A/T.
Flush cooling system after repair of A/T.

If ATF contains frictional material (clutches, bands, etc.),
replace radiator and flush cooler line using cleaning solvent
and compressed air after repair of A/T. Refer to CO-14,
"RADIATOR" , CO-39, "RADIATOR" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.

Changing A/T FluidALS000GC
1. Warm up ATF.
2. Stop engine.
3. Remove the tightening bolt for ATF level gauge.
4. Drain ATF from drain plug and refill with new ATF. Always refill same volume with drained fluid.

To replace the ATF, pour in new fluid at the charging pipe with the engine idling and at the same time
drain the old fluid from the radiator cooler hose return side.

When the color of the fluid coming out is about the same as the color of the new fluid, the replacement
is complete. The amount of new transmission fluid to use should be 30 to 50% increase of the stipu-
lated amount.
CAUTION:

Use only Genuine NISSAN Matic J ATF. Do not mix with other fluid.

Using automatic transmission fluid other than Genuine NISSAN Matic J ATF will cause deterio-
ration in driveability and automatic transmission durability, and may damage the automatic
transmission, which is not covered by the warranty.

When filling ATF, take care not to splash heat generating parts such as exhaust with ATF.

Do not reuse drain plug gasket.
5. Run engine at idle speed for 5 minutes.
6. Check fluid level and condition. Refer to MA-28, "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2.
through 5.
7. Install the removed ATF level gauge in the fluid charging pipe.

2. Using releasing agent, remove double-faced adhesive tape from the road wheel.
CAUTION:

Be careful not to scratch the road wheel during removal.

After removing double-faced adhesive tape, wipe clean traces of releasing agent from the road
wheel.
WHEEL BALANCE ADJUSTMENT

If a tire balance machine has adhesion balance weight mode settings and drive-in weight mode setting,
select and adjust a drive-in weight mode suitable for road wheels.
1. Set road wheel on wheel balancer using the center hole as a guide. Start the tire balance machine.
2. When inner and outer unbalance values are shown on the wheel balancer indicator, multiply outer unbal-
ance value by 5/3 to determine balance weight that should be used. Select the outer balance weight with
a value closest to the calculated value above and install it to the designated outer position of, or at the
designated angle in relation to the road wheel.
CAUTION:

Do not install the inner balance weight before installing the outer balance weight.Oil grade and Viscosity:

Before installing the balance weight, be sure to clean the
mating surface of the road wheel.
Indicated unbalance value × 5/3 = balance weight to be installed
Calculation example:
23 g (0.81 oz) × 5/3 = 38.33 g (1.35 oz) = 40 g (1.41 oz) balance
weight (closer to calculated balance weight value)
Note that balance weight value must be closer to the calculated
balance weight value.
Example:
37.4 = 35 g (1.23 oz)
37.5 = 40 g (1.41 oz)
a. Install balance weight in the position shown in the figure at right.
b. When installing balance weight to road wheels, set it into the
grooved area on the inner wall of the road wheel as shown in the
figure so that the balance weight center is aligned with the wheel
balancer indication position (angle).
CAUTION:

Always use genuine Nissan adhesion balance weights.

Balance weights are unreusable; always replace with new
ones.

Do not install more than three sheets of balance weight.
c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 7.5 g (0.26 oz) each or below.

If either residual unbalance value exceeds 7.5 g (0.26 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
