Transmission Oil Review

[xtreme_s14]

Ummm.. Yeah, AMS oil is definitely the way to go motor and transmission wise. I've yet to try it on my Kaaz differential.. Anyone care to try?

Are you guys aware of AMS Oil's warranty? You guys should really read up on their stuff. If you happen to destroy your motor in belief that it was caused by their oil, they'll ask for a sample of the motor oil to check the chemical properties that they claim should not/will not harm your motor. (Something along those lines)

They're oil is supposedly capable of 25,000 miles or one year, whichever comes first. As much as I'd like to save myself some money, I still would prefer to change it at every 2,500-3,000 miles or three months, whichever comes first. Research their stuff, it's pretty interesting!

@slider2828

So why'd you try so manny different oils, what problems were you having?

I'm down to give AMSOIL a shot but I wouldn't like to end up still having the same grinding problem afterwards...

I would think that an oil with a higher weight than what i have now (Royal Purple 75w-90) would be better since it would provide more lube for shifting

Thats why I'm just a little sketchy on switching out the oil for the exact same weight and expecting better performance. I'm not an expert on gear oil by any means though, so I wouldn't know if it really could make a difference...

Manual Transmission & Transaxle Gear Lube 75W-90 Product Code: MTGQT-EA

You can order via this site AMSOIL Synthetic Automatic and Manual Transmission Fluid

I don't think they will ship overseas cause its oil maybe? If NONE of you guys can find some I have a local place that carries ALL of the lines of Amsoil. I can get it for you guys pack it and ship it. Place is called Vic Hubbard in Hayward, but like I said I can ship it if you guys can't find it.

Let me know.

I switched to this as I tried to the Sever Gear from Amsoil and this one is better.... I just did it over the weekend. Immediately noticed the difference.....

To add to this I am a dealer and can have it dropped shipped right from the factory to anyone and my price will probably be better than the stores and I know it will be better than if you just go to the Amsoil website. Pm me for anything you need!

Also me and a friend both run the dominator race series oil in the motor and both love it! I run amsoil in everything I own!!

with all this talk about amsoil in this thread, I'm considering giving it a shot, but I'd really like to know beforehand if its possible that it will solve my grinding.

@fliprayzin240sx
lol, thats almost exactly the issue I posted about 2 posts up....

other suggestions?
i

I always like lucas's transmission oil additive, and thought one day i would try their "lucas HD".... read below... But for you if you want synthetic i'd do the motul shock proof stuff, in an 80w-90, or the NEO RHD, but its 75w-90... depends on what you want to spend too, but if you add a bottle of that lucas additive it should smooth things out nicely. make sure you are filling it to the proper level and make sure your vent tube isint blocked or clogged as well.

Beats all except in extremely cold weather.

never Ever EVER run this shit! I tried it, and had to drain it 20 miles later, it would not let me in any gear, shit was WAY too thick, even after it got warmed up, trust me i'm in texas, and its plenty warm, and its NO GOOD for our trannys.

Just finished my 5 speed swap (took 5 hellish days).

The tranny I bought was supposidly bad, so I was taking a high risk. I pulled the casing and saw the gears were worn, and I expected some heavy grinding in every gear.

Filled up with 2.4qts of amsoil 75w90 and it runs better than new.

Royal purple WILL kill your tranny

Nah, I changed the oil already. This RP is only about 1 month old. Maybe it just fucking sucks...

[tinys s14]

im almost dun with a 5spd swap n need gear oil so i got valvoline 75w-90 since they was no redline or amsoil. just wondering if its good or not or I shouldnt be cheap n buy some royal purple for 17 a quart

[scuba_steve91]

Amsoil tranny oil got rid of my 2nd gear grind. I love the stuff.

[drift freaq]

I used to run Amsoil in my 90 Hardbody pickup KA24E. Changed it out every 24k had the truck from when I bought it till 130k, it ran great when I sold it. I will run Amsoil in my HR VQ as well.

[nismoskyz]

Wow, some pretty strong claims towards AMSOIL.

i think i'm sold.

I guess I'll go for the 75w-90... I pray it works out and solves the 3rd gear grinding... we'll see then.

[fliprayzin240sx]

Same here, i just grabbed 3 qts of AMSOIL 80-90...$9.50 a pop, cheaper than RP which cost $15 a pop.

Anyways, Im gonna change my tranny oil tomorrow and install my Peak Performance Tranny mount...ill post up again with the outcome if this oil made a difference on my tranny.

[xs240]

So we need 2.5 quarts for tranny as a hole correcto?

[silviaz]

yes............. 2.4 in the fsm.

[ZenkiKid]

I had an occassional 3rd gear synchro grind before i changed my tranny fluid, then i switched to royal purple and the 3rd gear grind happens every single time i shift when the oil gets warm. I hate it. Im thinking of either going mt-90 or just buying the nissan oem fluid

[Bigsyke]

^^^^did you not read anything in this thread? Royal purple is garbage. Amsoil is the only thing to get, some napa stores are amsoil dealers.

Switch to amsoil I assure you your grinding will go away

Why 80-90? I didnt even know they sell this weight. It's not on the amsoil.com website at least.

I was gonna pick up the "Manual Transmission & Transaxle Gear Lube 75W-90".

It's $12.85 a quart on their website... Unless Zeller gets back to me with a better deal.

I have the exact same issue as well man (using RP). Hoping the AMSOIL will take care of it.

I'll post my results once I get it in, although it might not be for a week or so...

Just to clarify, that's 2.4 litres, or approximately 2.5 quarts. (2.5360517, says google)

[Bigsyke]

2.4qts and it doesnt make a big difference. 2 and 1/2 bottles to make it easy.

Huh, works in Appleton, WI in 9 different 240's.

FUCK ME, I grabbed the wrong fluid...I grabbed 80-90W Gear Lube instead of tranny fluid.

[nismoskyz]

Isn't that the same thing?

This is what I was looking to purchase...
says Gear Lube.

[fliprayzin240sx]

Nopes...I got this by accident...Gear Lube

[Zeller]

Yes, that is what you want! Use the sever gear lube for the diff! I sent you a PM! Sorry was busy yesterday. If that is costing you $12+ something a bottle without tax or shipping than yes I can save you a decent amount!

[Bigsyke]

snap, I got the GL5 stuff, which said gear lube, however it was 75w90, which SHOULD be the same stuff.

Although I'm no expert, if I were you I'd pick up the GL4 stuff, just to play it safe, since that's what Nissan recommends.

[nismoskyz]

So I swapped in the AMSOIL this Sunday...

Unfortunately, , I'm not as impressed as I thought I'd be.

Don't get me wrong, it's definitely much better than the 20K old Royal Purple it replaced and shifts are noticeably smoother. However, the primary goal/expectation of mine was that it would remove my 3rd gear grinding, which it didn't.

Grinding does seem reduced and, just as before, when shifting cold, grinding is entirely nonexistant (such a teaser!), but once things warm up, the grinding comes back as usual.

Nevertheless, the rest of my shifts do seem much smoother than before, so that's nice.
Also, it seems that once the trans warms up to a certain point, shifting becomes noticeably difficult in every gear. I was having the same issue with the Royal Purple I had before.

Now, is there any possible way for me to get the trans to shift as well when its warm as it does when its cold? A thicker weight or an additive of some sort?

I can't afford to swap out all the oil again, so soon.

Thanks.

[slider2828]

Try additives, I mean it preserves the life of your tranny, but its not a miracle worker that fixes tranny's..... All you can try is maybe just some Lucas Additives or something.... How are you shifting, lightened flywheel, lightened shaft hi rev shifting or just regular shifting its grinding....?

[nismoskyz]

Hmm, I've read good and bad things about Lucas Additives (even in this thread alone) so I'm not sure...

Hah, I wish I had lightened flywheel and shaft. No, I'm shifting on stock setup, just with a counter-weighted shift knob.

I know the trans is old and has had its share of wear and tear, but when I first start driving and the trans is cold (I'd say about 50-70 deg F or so), It shifts like butter in every gear, including 3rd, of course. That's the only thing that's giving me hope that my 3rd gear grind can be remedied somehow.

It just seems like it could use something thicker, although I wouldn't want to use something too thick...

[slider2828]

Yeah anything thicker would move you to sever oil like 90-140 Sever gear oil which is sold. I dunno what can help you, but it ain't going to fix all your grinding issues inherent to tranny issues.
