New Member/New to me 2013 M37

[Moveitsmikey]

Hello fellow members. I have been lurking around the community for a bit and finally decided to register here.. See Some really nice rides here. I'm Michael and I live in Arizona.

I just purchased a 2013 M37 w/ premium package. Its a one owner ( retired guy owned it ) certified Pre owned just turned 44k miles. Has FULL warranty left for 2 years unlimited miles.

It is stormfront grey metallic with black interior.( I've been told this color was only produced for one year is that true?) I'm absolutely loving this car so far. I previously owned a 2014 bmw F30.

I have some questions about the Y51 chassis since its new to me. Does anyone know the gear ratio in our rear diffs and is it indeed a VLSD?

Also I plan to change transmission fluid because I'm a huge stickler with maintenance, along with rear differential. I did some searching and low ans behold our transmissions don't have a dipstick so is the only way to change the fluid is to drop transmission pan? Also do these transmissions have a filter or just a screen?

Sorry for the lenghty post. Ill attempt to upload some photos soon
Regards
Michael.

Welcome to the forum!

Quite a few of us in AZ. Welcome to the M. I would only have the dealer change the transmission fluid. So much can go wrong. Better to have them responsible for it.

Welcome to NICOclub.


3.357.
That is your gear ratio in the back. It is not a mechanical limited slip differential, but I assure you that for most intents and purposes of this class of car, the braking system will be more than adequate.
Page 193 of this document has more info on your diff:

It is part of our factory service manual, which I like to describe as a Haynes/Chilton manual on steroids. I have the website linked in my signature.

The sport models come with limited slip diffs i think. The regular models don't. As for the transmission its "sealed" and apparently very hard to replace the fluid dealership recommends it at 60,000. My transmission went bad and i got it replaced under warranty so i didn't need new fluid but its around 200$ at the dealer for a trans flush i think. I think there's a do it yourself guide for the rear diff fluid i changed it on mine a while ago currently at 60,000.

Welcome to the forum!

Thanks so much for the warm welcome.

Thank you. I don't have a problem going to the dealer for this, but my gripe is I don't want to run OEM fluid. I'm a believer in amsoil and it meets recommendation for our transmissions. I doubt they would not external fluid for the procedure.

Wow that's odd. I would of thought these are fairly reliable transmissions. Did I make a mistake buying one now? Sure hope not.. Love mine...

I think it was a one off problem. Never heard of anyone getting my problem.(car would jerk heavily/not even shift had to have it towed to the dealership)

Oh wow. Almost sounds like a manufacturing defect. My sister has a 2013 rav 4 and her transmission went out just before her warranty ended. I think hers was doing the same thing..

Yeah im so happy that i made it in before my warranty ended. It would've been very expensive

Congrats on the new rig & Welcome. We’ll need some pics however, to document the purchase.

Thanks a lot! I will get some uploaded soon. Interior and all. I'm loving the color. It looks great under the sun.. Hey quick question is this forum supported on tapatalk? Or maybe a Facebook group? I hate navigating through the website...

[Mark Linkous]

Hello,
Congrats on the new purchase! I too just picked up a 2012 M37x on Friday replacing a 2011 G37x.
As a former 2004 M45 owner, I cannot believe just how much they have changed.

Sorry to ramble on as this is your thread. May your new car bring you years of motoring pleasure.
Best,
ML

Micheal,

I'm not a fan of the factory fluids, in fact I asked the Nissan dealer and they didn't even use the factory stuff. The cost is way too much.

I changed out the front and rear diffs, transfer case and transmission all with Amsoil. I love that stuff, I know everyone has a favorite but I really like the stuff. I went to the Nissan dealer due to a cheaper price and I could bring in my own fluids. I've also come to know and trust their master mechanic and is the only person I have trust working on my car.

The transmission is a sealed system and is a drain and fill only, plus the mechanics connect some computers up and based on temp and other data it drains fluid at a certain rate.

Let us know how it goes and welcome and good luck.

Andy

Hey thanks Andy. I appreciate the warm welcome. Funny you mention amsoil because that's all I use myself as well.

I just did an oil change with the amsoil Signature series. As well with the gear oil in the rear differential. 75W90 severe gear. Next is transmission.

I am also not a believer in OEM fluids. Its a huge marketing scheme for the company to make more money. To change fluid every 30k miles with conventional transmission fluid is a joke.

I did talk to one of the service advisors at infiniti about a transmission service. He told me that if it has 80k or more they don't flush the transmission with the machine and they ususlly just do the drain and fill method.

I had then mentioned I have low miles. (45k) he told me with low miles like that I have the option to flush it via machine. 12 quarts
through the trans, 150.00 for labor, even said it was fine if I wanted to bring my own fluid.

[Big_Tone]

I'm curious about Tapatalk, too. I thought this forum was on it, but I don't see it

[Malbec 56 Beast]

That's weird, I was told by Nissan and Infiniti that our cars are only drain and fill.

I really like this stuff, I feel way more configurable with Amsoil than any factory stuff.

Good luck

Happy to hear your am Amsoiler

When I search nicoclub the only result that shows is frontierclub.org there is q50 and q70 category amongst others but no actual nicoclub, not a group on facebook either. This site is so slow every time I type it lags horribly. I hate it

Probably because not many people actually ask those questions so they just go with what's recommended.

I'm very meticulous and I don't want any Nissan fluid mixed with the amsoil. I feel it will take away from its integrity so I would rather have it all completely replaced.

I'm with you on that one. There simply is no better fluid, gear or engine oil. They prove it time and time again. I always notice a HUGE difference from the crap oil the dealer uses, to making the switch to SS. It always amazes me.

Ultimate long lasting protection. I also had my gear oil changed. That made a huge difference. Just imagine though how long your transmission and engine will last... With the least amount of engine wear physically possible... Given the facts on the oil and how its protecting... Amazing stuff....

[Larz]

I always use the dealer for this service. I don't want anyone messing about with such an expensive part of my car. Plus, I have a warranty and I don't want to give them any chance to say I used the wrong fluid, etc and deny any claims. I'm past 100k miles and it still shifts like new. Warranty goes to 150k so if it does go titz-up, only the dealer has accessed it and the service records for ALL maintenance is well documented ion their own system.

I get what you're saying but have a read here.

Not many people know this. I swear the dealership is fear based.

It is only drain and fill, according to the FSM. No way in hell I would flush this transmission, regardless of what the dealer says about mileage.

Thats what's recommended. Which is what the majority of people do. I've flushed several transmissions in cars I owned, even high mileage and it was fine. As long as the fluid isn't burnt and you have no shifting issues flushing is okay. You can flush on these, I had it already looked at which I'm in the process this week to do.
