is there anyone okay with your 370Z after 100K miles without ATF change?
 

I did read the maintenance guide. It said the 370Z's automatic transmission is maintenance free.

I really get confused here. Now I'm using my second Nissan genuine automatic transmission on my 370Z. I got it installed after its fluid had been changed when around hitting 100K miles and was soon broken after that ATF replacement. (it was a Nissan genuine AT fluid of course, because I got service at a Nissan dealership).

It does not mean that changing fluid surely did break it. I got my 370Z as a pre-owned one, and have no idea about what exactly its previous owners had put into it. (If in case they had put any third party ATF, then it might not be maintenance free, right?) - or it just unfortunately might be classified as a 'defect'.

Anyway I really do not want to see my transmission broken again. I want to keep my Z as long as possible even after I buy another car in the future. My dealership recommends me to get it checked everytime I take the oil change and replace its AT fluid basically every 100K miles.

I don't go to the track, and consider myself as a just normal daily driver with some rare spirited driving that I enjoy my zero to sixty when I enter to the freeway.

So, is there anyone in this forum okay with your automatic transmission without changing its fluid even after 100~200 miles? Is its fluid literally 'ever-lasting' as maintenance free? I've done pretty much research for this by myself, but still cannot make my decision.

:yum:

This title made me think.

Fuckin ATF is after our guns and our Z's?

I've been told many times not to ever swap the AT fluid in a car and the differential fluid IFF, they have high miles because of the muk and gum that builds up within the system. Basically that dirtiness that builds up in there helps fill in gaps and wear within the systems and so when you put in new fluid all that helpful gum comes out and thus leaving your stuff vulnerable... My $0.02. :)

However if you swap your fluid early enough and continue this practice you should be good.

would this logic work for all fluids (i.e. engine oil)?

OP, im starting to find your threads a bit disturbing....

Na haha I wish though, that's why they say that it's "maintenance free". Basically if you do the fluid swap you could mess your stuff. ESPECIALLY automatic transmissions. Now I know you hear about people swapping their tranny fluid and clutch fluid but well that's precisely the difference. AT vs MT manuals usually will go longer for the same reasons that you swap the clutch and swap your fluid. You can actually work with it as opposed with the AT. They are very delicate and they don't like it when you swap the fluid they get comfy in. Now I don't know a hole lot of details but that's how it makes sense to me.

Please don't take my word for it. Ask some mechanics you might know. Ask em this "is it suggested or good to swap out the transmission fluid on an automatic?" And make sure you mention your miles because that's a big variable.

As I know, the maintenance guide does not say other fluids are also maintenance free.

Rather it says the engine oil must be changed on some specific intervals.

Oh man please don't tell me people are going to mistake what I said and turn it into something it's not. I did not mention he engine oil or any other fluid at any moment. Only differential and tranny :)

I like to change ATF every 40000-50000 miles. Or sooner, if it gets very dark or smelly. 100000 miles is way too long.

While there is a bit of truth to the don't-change-if-miles-are-high theory (mainly with older ATs), it's not gospel. Depends on the lube and what's being lubed. With modern ATs/ATFs, it shouldn't be a problem.

Years ago, I asked what motor oil to use (when I didn't know any motor oil thread was not welcomed and closed), then someone answered to me that the best engine oil for my 370Z is an extra virgin olive oil.

Fortunately I did not know how to change oil by myself either, and later found out at a dealership that it must have been just a joke.

If I did, maybe I really might have tried it and sent my used sample for oil analysis..

:eek:

differential ??

370Z's VLSD fluid is also maintenance free?

Just curious.

Sorry I suppose newer models do need the service haha my mistake.

The diff fluid is serviceable at least every 30K miles. The VLSD fluid is not serviceable. That is why it sucks.

I own a 2010 370Z Sport, and my maintenance guide (of 2011) does not mention seperately that its VLSD fluid is also maintenance free.

Can you tell me where I can see the VLSD fluid is non-serviceable ??

You just did. The unit is sealed and is only replaceable. It is not a maintenance item.

manual is :bs: even the stealership mechanics who know a little bit say it is.

diff fluid ~30k miles depending on how you drive. lots of track or hard driving maybe just do it once a year.

ATF 30k-50k miles. i did mine at 45k recently

Did u know u can add tap water to fuel and get better mpg?




:ugh:

Stealerships are called dat for a reason.

also why the manual is written the way it is lol

their parameters will work if you drive 2k miles a year never passing 3500rpm

:bowrofl:

if we dont break anything the dealerships and manufacture dont make anything on the backend.

actually i may do a diff fluid change this year too. just did oil change and cleaned/oiled my intake filters over the weekend.

U just don't like "manuals" all together. :gtfo2:

atleast we can brag about our CSC costs :ugh2:

150k without changing ATF. I ended up changing it a few months ago and now I need a rebuild lol

ROFL XD I like that.

Im old school, 50K change fluids..diff, tranny,PS, PB, front diff, coolant etc. no problems in MANY years..:driving:

Yeah that's exactly why. You would do it in good time I believe the best or most ideal is every 30-40k miles but the longer it's set off the more likely one is prone to experience failure.

Again, I am not a professional nor am I licensed in any of this. I am only going by what I've been told in the past and what makes sense to me.

Since you mentioned oiling the filters. I also just recently cleaned and oiled my air filters, however I came across a thread on here where a member mentioned that using oil is no good for the filter because it can mess with MAF? Is this accurate? Or is it no biggie?

honestly i dont know. i've heard people say it before but considering filters are mass produced as dry or oiled on such a large scale vs being some random DIY mod i feel it's not that detrimental to the car's performance.

i pulled mine off, washed them, let dry, oiled, let dry, replaced on the car. i'm mad at myself because i think i waited too long because i can actually feel it pulling harder now. guess they were well past a good cleaning.

The key to K&N filters and oiling is not to over oil them, and like Presto did, let them dry... The challenges comes when some folks have so much oil on the filter it drips off.... Last car I had with an oil bath air filter was a 1949 Chrysler...:rolleyes:

:iagree:

the instructions for the "recharge" kit say after oiled let dry for 20 min. i did mine mid oil change and just bullshitin with my dad in the garage. i think mine sat about 45-60 min before i installed then i backed it out to give it a quick wash........then into the garage at home for a day since it was cold and stormy monday lol

soooo yea this time isnt a great example of a dry time to good to drive scenario :bowrofl:

i will say if you pick up the filter and theres drops running down it or a ring on the ground, wipe the excess off, and let sit a bit longer. you may have gone a little heavy but it'll dry.

Go figure.....:eekdance:

I think a good solution is pick up another set so you can swap it out right away and then have the next one dry and ready to go for the next cleaning.

speaking of which I'm probably going to check mine later...

i thought of that but it doesnt really take that long.

pick a small window of time on a sunday or something. jack it up, drop the bumper, and go.


giggity.

initial water dry takes a little time but if it's daylight let the sun speed that up. oil technically calls for only 20 min but i'd say go 40 min to be sure. not liek it hurts it.

Yeah you know what I did over soil mine :$ as much as u hate to admit :(

The Porch guys only oil the incoming air side, too much oil can play havoc with the MAF

So do you mean your transmission was broken after its fluid change at 150K miles around .. ??

You know, not all modern automatic transmissions are maintenance-free.

I actually somewhat agree to that no-change-at-high-miles theory because in my experience my Z got pretty faster acceleration (like having higher torque) just after its ATF change at around 100K miles, but soon some weeks later after all it got broken.

I guess that previous transmission must have malfunctioned after its fluid change anyway ..

If you drive the car hard it needs to be changed. I've changed mine twice and it was nasty. The car only has 35K on it but it's tracked with a supercharger. I just had level 10 rebuild it and the fluid that came out of it was so full of clutch material that I'm surprised it wasn't acting up. It's just my 2 cents, but I've never left a fluid in a car for 100k.

.....NO SH*T!!....#sarcasm :facepalm:

:wtf:

once again, OP, i find most of your threads and posts appalling and disturbing....

OP, no offense, but you specifically made a thread because you didn't know how to work the paddle shifters, which to me translates to you don't know how to drive an automatic....it's no mystery that your tranny went bye bye.

@FPenvy, side note, i came across one of your youtube vids and your exhaust sounds SICK!!!!! :excited::excited::excited::excited::excited:

Please do not put the olive oil to your engine.

It would do harm.
