So I just took the plunge into my first tranny fluid change and took some pics. I used 5 quarts instead of flushing all of it.

Important Note: Nissan Matic J was replaced with S.

THINGS YOU’LL NEED:

• Nissan Matic J transmission fluid (got lucky and found some on eBay but most likely you’ll have to go to a Nissan dealer and pay $15/qt)
• 10mm Socket
• Bucket
• Plyers
• A friend to help
• Funnel
• Ramps/jack stands (so you can fit the bucket under)

STEPS:

1. Lift car and remove splash guard.

2. Remove the engine cover so you can get to the charging pipe behind the engine.

4. If you’re replacing X quarts of fluid, fill your bucket with X quarts of water and make a line at the water level. This way you’ll know when do stop draining.

5. Get all your Nissan Matic J transmission fluid opened and lined up so you or you’re friend can continuously pour. Start your engine (nothing will drain without the engine running).

6. Get under the engine with your bucket ready. You’ll be removing the smaller hose from the radiator (see picture).

7. With your plyers, squeeze the hose clamp and slide it farther up the hose.

8. Put your bucket directly below the end of the hose and get positioned so you can watch the fluid level reach the line on the inside of the bucket.

9. Pull the hose off the radiator. I used plyers on this step but it might be easier to just use your hand. TIP: JUST AS THE HOSE RELEASES FROM THE RADIATOR, GIVE IT A PINCH TO STOP THE FLUID FROM SPRAYING ALL OVER YOUR GARAGE!. Otherwise you’re garage will look like this.

10. Yell to your friend to start pouring. Aim the hose at the bucket and stop pinching. Watch the fluid fill the bucket. As soon as it reaches the line in the bucket, pinch the hose again and reconnect it to the radiator. Hopefully all the old fluid is in your bucket and not on your body/garage floor.

11. Slide the hose clamp back to the end of the hose with your plyers.

12. Turn off your engine and give your friend a high five or a kick in the nuts, depending on his performance.

13. Put the splash guard back on. Screw the dipstick bolt back into the charging pipe. Put your engine cover back on.

14. Good work, now go drink a beer and order some more mods for your FX.

Drain Plug

Checking Fluid Level

Important Notes

Actually the transmission holds 10 3/4 quarts. The 30,000 and 60,000 mile services call for a drain and fill which takes about 3 1/2 quarts to do.

OP what I would do is buy 8 quarts, drain the pan, and refill with 3 1/2 quarts. Drive 50-100 miles and repeat the process. Give the car about 1-2000 miles and repeat. That way you don’t shock the tranny all at once with new fluid. I don’t think the tranny has been hurt unless you track your car but check your fluid ASAP. If it is dark or brown and smells burnt, you probably need to ignore my first advice and take it to the dealer for a complete flush and fill.

The tranny fluid is Nissan S-Matic, it replaced the J-Matic and is the only transmission fluid recommended for our engines.

—————————————

I had my tranny fluid changed last month. Me and my buddy did it with the car on the hoist. We used the drain plug on the tranny oil pan. Drained out about 4~6 qts. Then we filled another 4 ~ 6 qts back to the oil pan (depending on how much you drain out). The turn on the engine, with the brake on, shifting from P to R, to D, then D to R to P, each gear stays about the 20 secs to let the new fluid to mix out with the old fluid. Then we did the process again. After that test drive the car in manual mode for about 10 mins. Then measure the fluid level. If not enough, then top out from the tranny dip stick tube with a thin tube funnel.

I do my tranny fluid change about every 30k miles. The car is running fine, no issue with the tranny.
