According to the manual, you have to use the OEM tranny fluid or risk voiding the warranty. From what I see, it is 80$ per liter and uses 8-9 liters per change.

Dodson Fluid is another alternative as well.

Thousands of pages likely could be written on this subject.

I'll summarize, very quickly. If you daily drive, OEM is fine. If you track, OEM without a high quality transmission cooler is not a very good idea (unless you like changing every 1800 miles).

HKS has it's own fluid. Cannot speak for how well it works, but likely it's good.

WillAll was the first comer to the replacement market, and is a high quality fluid. I know more about the package, but respect the nice people who gave me the details, so I'll just let you know it is a great gear oil. We don't know about long term clutch effect, but so far, no problems. It will stand up to the high temps of the GR6 transmission very well.

Dodson came later, with much less hoopla and fanfare, and is a little more economical. I also know this package, and is also a great gear oil. It has chemistry distinctly different than the WillAll, and may be a little more synchro friendly over time, while sacrificing some extreme pressure gear protection (but both should be head and heels above the OEM, which will suit for regular non-high performance usage if you don't have a tranny cooler, but is a relatively thin ATF type fluid which have come a long long way over the last 20 years, but are still not as good for gears as a true gear oil like WillAll or Dodson).

Pentosin is a special, very highly refined synthetic fluid. Its base is not even petroleum, as far as I can tell. There are many users out there, and it is reasonbly close to OEM viscosity. I do not know what the long term with Pentosin will be, but BMW trusts it to be "lifetime fill" for some of its transmissions.

If you put something other than OEM and have a transmission problem, how will that affect the warranty?

Nissan has gone both ways on this. I've heard of trans that are filled with Willall being warrantied and others denied because of Willall or aftermarket fluid. I don't think there is a clear cut answer on this one.

+ a gazillion. Inconsistent answers on this one. For the clearly structural related failures (clutch seals, solenoid failures, etc.) they have warrnted with aftermarket fluid, because there is NO WAY the fluid could have caused those failures.

For highly modified vehicles that have been launched and with WillAll in the transmission, warranties have been denied. Stated causes have varied.

There are inbetween cases that have gone each way. Not consistent to this point.

Safest way: Stay with OEM, but if you track, get a transmission cooler. BUT.... Nissan could deny warranty based on presence of a cooler as well.

I've just imported a MY11 GT-R into Malaysia from the United Kingdom. This is the 530bhp version. Over here our weather is HOT & HUMID all year long. During the day temperatures are from 32 degrees celcius to 38 degrees celcuis depending which months of the year.

I will be adding a FORGE Transmission Cooler Kit along with Willall Racing's Front Differential Cooling Kit to keep things cool. For the differential fluid a local shop recommended OS Giken. Said it's more suitable to our local climate.

Now it all boils down to which tranny fluid? I emailed Willall and they recommended their VICTORY SPEC as I said over in Malaysia we can run the cars at high speeds due to our 'soft laws' of speeding.

Both WILLALL RACING & DODSON is available locally. So I'm actually quite confused to which tranny fluid to purchase. I might track the car a little bit. As you know we have our F1 Circuit avaiable for track day sessions. Oh yes, might also upgrade the car's power to SWITZER P800 Package.

I believe based on our weather and driving styles, every 10,000kms/6,000 miles (if not using OE tranny fluid) is good to change out the transmission fluid. Also remove the solenoid valve body every 30,000kms/18,750 miles for servicing.

Malaysia doesn't officially sell the GT-R here so there are allot of grey imports coming in from the UK and Japan. No warranty. Everything is on our own. The only thing we can do is rely on TUNER SHOPS that specializes in this car.

So any feedback would be much appreciated. Suggestions?

I would stick with oem and I doubt you will reach high temp with 2012 GTR with a cooler. So to me the fluid are within the temp specs. Locally the two GTRs have bad tranny are both on none oem fluids. It might or might not be the cause, but no issues with me and bro's GTR on oem.

I am using Pentosinn FFL-4

No warranty so no problems. Drives better than OEM and very smooth.

I have seen a few cars running 1000whp on Pentosinn FFL-4 and works fine (a lot of fluid changes).

My understanding is willal "light" is the same color as OEM, and still protects much much better....at least thats what the guys at Forged told me

Should make it a little more difficult for Nissan to deny your warranty unless they are going to do lab tests on the oil.

Oil has been running pretty good in my 09 tranny so far.

Crazy GTR tax on even some transmission oils.

We had in the past here a vote poll for Transmission oils and here it is:

We have been using Motty's fluid from Japan with great results on a client's SPE650 at the track with no DCT cooler.

Chaz has quoted the following:

"First off: the Moty's
- Driving around on the freeway and in traffic, I noticed regular temps of 190-193, with temps hitting around 204 when coming back down from BW in 98 degree weather in some traffic.
- On track, same config and ambient temps last time (#13 CW, 95-100 degrees) I hit trans oil temps of 248 with a 2:06.95. This time, the highest the oil hit was 233 with a 2:05.36 (I know I'm still slow, leave me alone LOL). Transmission shift feel was the same with the OEM fill with R mode. Driving around town though the car definitely feels smoother with the Moty's.
- All in all, excellent fill with noticeably lower temps on track. Great option vs. OEM for people who run on track. Price is excellent too."

Been running Dodson GR6 fluid and I love it. Haven't tried Pentosin or Willal, but Dodson was an improvement over OEM.

Whether or not I'll reach high temp with a cooler kit, its for peace of mind along with better tranny fluid. I believe more care is needed for the GR6 gearbox. And in Malaysia we're able to run up very high speeds on our highways for long durations.

This is why better tranny fluid, tranny cooler kit and a differential cooler kit is advisable for our climate and driving styles.

Pentosin FFL-4 since a lot of the Malaysians gt-rs use this fluid. Since you have no warranty I would say try it.

You can try Moty's from Japan, lots of JDM tuners use it for their GT-R.

I got a 20L pail from N1Racing. Can't comment on its performance since I'm going to fill mine this weekend. All I can say is that the price is much more reasonable compare to other aftermarket oil, basically half the cost based on my calculations.

Let me know your thoughts on Moty's. Seems allot of people have gone off elsewhere after trying WILLALL. Seems like more people prefer Pentosin, Moty's and Dodson.
