Changing A/T FluidACS0079Z
1. Warm up ATF.
2. Stop engine.
3. Loosen the level gauge bolt.
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 stipulated 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 deteriora-
tion in drive ability and automatic transmission durability, and may damage the automatic trans-
mission, 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 AT- 1 2 , "
Checking A/T Fluid" . If fluid is still dirty, repeat step 2
through 5.
7. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
8. Tighten the level gauge bolt.
Checking A/T FluidACS007A0
1. Warm up engine.
2. Check for fluid leakage.
3. Loosen the level gauge bolt.
4. Before driving, fluid level can be checked at fluid temperatures
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 fluid level with engine idling.
d. Remove A/T fluid level gauge and wipe clean with lint-free
paper.
CAUTION:
When wiping away the A/T fluid level gauge, always use
lint-free paper, not a cloth one.A/T fluid: Genuine Nissan Matic J ATF

e. Re-insert A/T fluid level gauge into A/T fluid charging pipe as far as it will go.
CAUTION:
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 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 fluid to the A/T fluid
charging pipe.
CAUTION:
Do not overfill.
5. Drive vehicle for approximately 5 minutes in urban areas.
6. Make the fluid temperature approximately 65°C (149°F).
NOTE:
Fluid level will be greatly affected by temperature as shown in the figure. Therefore, be certain to
perform level check operation checking warm up condition 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 A/T 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" (for VQ35DE) or CO-39, "RADIATOR" (for
VK45DE) and AT- 1 4 , "
A/T Fluid Cooler Cleaning" .
9. Install the removed A/T fluid level gauge in the A/T fluid charging pipe.
