Transmission Oil Service

[T88turbo]

Has anyone performed an automatic transmission oil change yet?

I have the nissan j matic oil for the 2003 coupe.

What else is required? do they run filters? Are there any gaskets that need to be replaced?

Also there is an option either to drain the oil from the transmission or feed it through from the radiator hose to fully flush the system until clean oil is visible when disembarking the pipe. What method have you guys used?

Regards

Never done it. but this should help.

Changing A/T Fluid ACS004LA

1. Warm up A/T fluid.

2. Stop engine.

3. Remove the tightening bolt for A/T fluid level gauge.

4. Drain A/T fluid from drain plug and refill with new A/T fluid. Always refill same volume with drained fluid.

To replace the A/T fluid, 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% 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 deterioration

in driveability and automatic transmission durability, and may damage the automatic transmission,

which is not covered by the warranty.

When filling A/T fluid, take care not to scatter heat generating parts such as exhaust.

5. Run engine at idle speed for 5 minutes.

6. Check fluid level and condition. Refer to AT-13, "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 fluid charging pipe.

Checking A/T Fluid ACS004LB

1. Warm up engine.

2. Check for fluid leakage.

3. Remove the tightening bolt for A/T fluid level gauge.

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 position. 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 fluid level gauge, always use lint-free paper, not a cloth one.

e. Re-insert A/T fluid level gauge into 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 charging

pipe, with the 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 charging

pipe.

CAUTION:

Do not overfill.

5. Drive vehicle for approximately 5 minutes in urban areas.

A/T fluid: Genuine Nissan Matic J ATF

Fluid capacity: 10.3 (10-7/8 US qt, 9-1/8 lmp qt)

Drain plug:

: 34 N·m (3.5 kg-m, 25 ft-lb)

Level gauge bolt:

: 5.1 N·m (0.52 kg-m, 45 in-lb)

AT-14

A/T FLUID

Revision; 2004 April 2003 G35 Coupe

6. Make the fluid temperature approximately 65°C (149°F).

NOTE:

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.

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 charging pipe, with the

gauge reversed from the normal attachment conditions

as shown.

8. Check fluid condition.

If fluid is very dark or has some burned smell, refer to check

operation of A/T. Flush cooling system after repair of A/T.

If A/T fluid 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-12, "RADIATOR"

.

9. Install the removed A/T fluid level gauge in the fluid charging pipe.

bloody hell, it is a bit long winded and not sure why you would have engine idling at step 4 when you pour in fluid...

that is a bit odd.

Just a question, how often is the ATF meant to be replaced/flushed?

i do mine every second service or 10000k

[iamhe77]

Only done mine once in 70,000km's.

Service was performed my a GOOD Nissan dealership who put in Matic D which is a synthetic AT fluid (Matic J is not synthetic).

I was told that the 5 speed tiptronic was a "sealed" unit and does not have a filter.

The Nissan tech also said that once the trans is sealed, the fluid is not required to be changed!

Don't know about that, but my trans has been running perfectly for the past 2 years so who knows?
