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.


  • 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)


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.

Parts that I replaced:

  • OEM Axle Seals: 38342-81X00 (driver side) 38342-81X01 (passenger side)
  • Throw-out Bearing
  • Clutch (I used a 5th gen setup)
  • Stillen Lightened Flywheel
  • Obviously a tranny. I used my old ’95 tranny with 108k. (My current car has 180k)
  • Amsoil synthetic GL-4 tranny fluid. Pricey but recommended.

Alright, step by step removal down to the tranny. First may I note that I think I did this with removing the least amount of stuff possible. I left the cross member on and y-pipe on. Removing these will obviously make removing the tranny easier but is optional. PS: if you remove the cross member you will need to support the engine.

Step One:
Start draining the fluid. Draining the tranny fluid takes a long time so start with this right away. I didn’t and I had to wait for while. This pic shows the bolt that is removed to do this.

Step Two:
Remove the driver side wheel.

Step Three:
Remove the caliper. My 300zx calipers were held on by 2 17mm bolts in the back. Use a wire or zip tie to hold them on the springs so they don’t hang by the brake line.

Step Four:
Remove the Rotors. Mine just slid right off.

Step Five:
Now remove the cotterpin and the washer behind it. Use a pliers.

Step Six:
Remove the 36mm axle nut. Impact gun is strongly recommended. There is also a washer behind it so keep track of that too.

Step Seven:
Disconnect the hub from the struts. It is a 19mm nut on a 17mm bolt.

Step Eight:
Now pull the hub off of the axle. I also used a hammer to help start push the axle out. I again used a ziptie to hang the hub from the strut so it would not pull the ABS line tight.

Now to attack from under the hood. Here is my engine compartment before doing anything. Mostly a mess, I know.

Step Nine:
Remove the intake. Disconnect the vac hoses, MAF and air temp plugs, and disconnect from the throttle body.

Step Ten:
Remove the battery and battery tray.

Step Eleven:
Remove the Starter. This involves disconnecting the big positive cable and the other connector. Then unbolt the 14mm and 17mm bolts.

Step Twelve:
Remove the slave cylinder. This was held on I think by two 14mm bolts. They are hard to get at so I had to use a wrench. Then also remove the ground wire that is bolted right next to where the slave cylinder is.

Step Thirteen:
Remove the tranny mount. First remove the long bolt that goes through it. Then the 4 bolts that hold it onto the tranny. Also notice the oil everywhere?…no wonder there is none in my tranny…it is instead all over everything else!

Step Fourteen:
In order to access a few tranny bolts, it is also necessary to remove the shifter linkages/rods from the tranny. It is ok to let them hang from where they connect to the shifter. Also 1 of these bolts is a pain to get at with out taking off the cross member but I did it with a wrench.
(sorry no pics of this)

Step Fourteen point five:
Also make sure the crank position sensor on the tranny is unplugged and the gear sensor is unplugged. I removed the crank position sensor completely.

Step Fifteen:
Now you should have everything off of the tranny. So now remove all the bolts holding the tranny onto the engine. There should be 8 since one was already taken off with the starter and one with the shifter rod. KEEP TRACK OF THE BOLTS! There are different sizes, what I did was I drew a picture of a circle and placed the bolts on the circle relative to each other on the tranny. 2 of the bolts on the bottom of the tranny I could not completely remove with the cross member still on, but I didn’t need to since they were completely unthreaded from the tranny. Once all the bolts are out its time to take off the tranny. What I did which isn’t recommended as the best, was place a jack under the tranny (but not pushing up on it) and then I used a screw driver to pry it from the engine. Then with the tranny sitting on the jack, I lowered it down. This isn’t recommended cause it is very hard to balance a tranny on the jack.

Step Fifteen point 5:
Remove the clutch. It is held on by I think 10 12mm bolts IIRC.

Step Sixteen:
Remove your flywheel. This is held on by 8 14mm bolts. I used an impact gun with a 14mm impact socket. These bolts are very tight and using a ratchet is difficult unless you can effectively stop the flywheel from rotating.

Step Seventeen:
Assemble lightened flywheel from stock ring gear, timing gear, and the stillen piece.

Step Eighteen:
Reassemble everything in reverse order, making sure to torque everything to spec and to replace the axle seals, and then refill with 4.8ish quarts of tranny fluid. DO NOT use an impact gun to install the flywheel and clutch onto the engine. These bolts are weak and can break…don’t ask me how I know.
Edit: Thanks to nismology for pointing this out, when refilling the tranny, do it with the car level on the ground and refill until oil comes out of the refill hole (It takes approximately 4.8 quarts)

Other notes…reinstalling the tranny was a major PITA since it’s so heavy. I recommend using a tranny jack. If you don’t have a tranny jack and if you aren’t super buff, you should remove the passenger side axle. It’s the same steps as the driver side with the addition of removing 3 bolts for the bracket that holds the axle to the engine.

Matic-D may not be a technical requirement but it is certainly and unquestionably the safest choice … if one cares what the FSM says, that is.

In having owned my 1999 since MAR of that year and in having personally completed the vast majority of services and repairs since the expiration of the manufacturer’s warranty, I feel comfortable in letting those interested know what I’ve found works. Nonetheless, if others hold differing perspectives, based on their notable experience and long-term trials and errors, with regard to a specific topic (this case being the 4th generation Nissan Maxima) those individuals should feel free to espouse those perspectives in an effort to contribute to assisting those who’ve asked for assistance.

Thanks to Kirill, we just ordered a set of “Street” Selector Springs for our 2002 6-Speed Supercharged 5thgen Maxima. Will post a review afterward. The owner Peter will get back to you quickly. This is only for the manual FWD RS6 6-Speed  and RS5 5-Speed Transmissions. Also, if you are having issues with reverse just make sure the spring cup on the larger spring is not upside down.

Overview & Purpose from Vision1Racing

From the factory, Nissan utilizes two springs within the transmission to “center” the shifter in the 3/4 gate. These OEM springs are very weak and often cause 3rd gear lockout issues when attempting to quickly shift. This is simply due to the driver overpowering the spring’s ability to line up the shift mechanism in the 3rd gear fork. VisionOneRacing offers two kits to fit the driver’s needs.

Our Street Kit is 200% stiffer than the factory and provides a nice, crisp feel. This is truly how it should have come from the factory. Our Race Kit utilizes a higher grade spring steel and is over 300% stiffer than the factory. This will provide the necessary “kick” to the shifter when slamming them gears down the track.

Both kits have received excellent feedback and have propelled the V1R Sentra into the 9’s, being the first QR to do so. They have also helped send the all-motor Maxima into the 10’s with many other success stories along the way!

It’s also worth noting that I highly recommend aftermarket shifter bushings when using our Race Kit. These can be had from 2J Racing among others.

Overview & Purpose from Vision1Racing

The Diamond Claw® Crank Lock utilizes precisely sized CBN particles with a hardness of 10,000 Vickers that effectively LOCK your flywheel and harmonic damper in place. With a thickness of only .008″ – Driveline alignment remains unaffected.

Previously only available for the most common platforms – including the Nissan GTR, Vision One Racing remains focused on bringing these solutions to the entire Nissan family. Protect your most expensive and crucial components with this small yet powerful addition! At an affordable cost, the Diamond Claw will be reusable for virtually the entire life of your engine.

When modifying engines and pushing them beyond their designed capabilities, harmonic vibrations are your worst enemy. Long strokes, balance shaft removal, increased RPM, single mass flywheels, turbocharged applications, and even higher compression all are capable of contributing to increased harmonics. These micro-vibrations often times cause surface welding (also known as “fretting”) on the crankshaft, flywheel and other expensive components.

The V1R Diamond Lock® helps to prevent flywheel bolts from backing out with increased RPM and power output. In the event that the flywheel does become loose and begin to vibrate against the crank, the Diamond Claw® can help protect the crankshaft and prevent further damage.

We’ve seen firsthand the detrimental effects that fretting can pose – sometimes even destroying a crankshaft beyond use. While mitigation techniques have been around for ages, nothing has proven to fully prevent this anomaly… UNTIL NOW!
