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

A/T Fluid Cooler CleaningACS007A1
Whenever an automatic transmission is replaced, the A/T fluid cooler mounted in the radiator must be
inspected and cleaned.
Metal debris and friction material, if present, can become trapped in the A/T fluid cooler. This debris can con-
taminate the newly serviced A/T or, in severe cases, can block 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 cooler 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. Position an oil pan under the automatic transmission's inlet and outlet cooler hoses.
2. Identify the inlet and outlet fluid cooler hoses.
3. Disconnect the 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 the 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 the Transmission Cooler Cleaner only with ade-
quate ventilation.

Avoid contact with eyes and skin.

Do not breath vapors or spray mist.
6. Hold the hose and can as high as possible and spray the Trans-
mission Cooler Cleaner in a continuous stream into the cooler outlet hose until fluid flows out of the cooler
inlet hose for 5 seconds.Level gauge bolt:
