Finally, last week, the dealer installed a new gearbox on my Leaf. I didn't get to see the inside of the old reduction gearbox, so we'll never know what the production error was that make it leak. I think it must have been a faulty oil seal.

Now that the whole reduction gearbox has been replaced, there's no need to worry about wear caused by driving without oil in the gearbox. But it's a pity we don't get to see what the damage of approx. three years driving with almost no oil actually was.

The Nissan dealer didn't charge me anything for all the work they did, nor for any parts. They just had me sign some kind of form that this part replacement was done under warranty.

Thanks to all of you who helped me to find out what the actual cause of the leak could be! The dealer needed a lot of convincing before they admitted something was wrong and also pin-pointing the problem on the seal inside the gearbox was not something they would have done without me telling them where to look (which I could not have done without the help on this forum).

Just to be safe, I will check for leaks after 6 months :roll:

I've been following your saga, so good for you...and kudo's to Nissan for (eventually) stepping up and doing the right thing!
Now you can think about putting some of that Valvoline ULV stuff in there (and see the miles/kWh gains)...

Yes, that would be interesting to see how much/little was caused.
It does tell us a few things, that the gears are built in such a strong way that missing lubricant isn't enough to destroy them immediately. If you drove an ICE around without any oil, the engine would be dead within a few miles of driving.
At least if you were in some bizarre accident in your Leaf that it lost all of it's gear oil, provided the gears were not destroyed, you could still drive it quite a long distance to a repair shop without worrying about an immediate seize up along the way.
Second, the amount of gear oil it in by default is more than enough to keep things lubricated properly, even if you wait a long time to change it.
Third, really thick gear oil is not necessary, provided what you use isn't so thin that it leaks between the seals, which is good news for those of us trying to squeeze out every last mile of range. :)

Re: How To: Reduction Gear Oil Change

Hello all. First post. We have entered the EV world with a 2013 Leaf bought a couple weeks back. I always like to do a service/fluid change when buying used vehicles as I don't know the history of the vehicle and I then know all fluids are new.
I came accross the reduction gear oil change during my research. Having read all 33 pages of this thread I am wondering if this would be OK to use.

https://www.amazon.co.uk/MANNOL-MN8207- ... C88&sr=8-3

I'm struggling to find geniune OEM Nissan Matic S ATF from my location (an small island off the North coast of Scotland) but found this on Amazon. Looks to have Matic S compatibility. Also need to find new washers if possibile as, again, struggling to find OEM here.

Thoughts appreciated.

This website rewrites Amazon links and breaks them in the process...

So, when posting Amazon links, use a URL shortener.

Here's your link, now fixed:

That sounds like good ATF. We used Valvoline full synthetic that is available in usa. I expect most light weight motor oil would work fine.

Our 2016 got totalled in 2019 at 37K miles so while the front cap including radiator etc was stripped off in the rebuild process we drained, flushed and refilled while we had line of sight view a three plugs. The fluid was very dark and both magnetic plugs were loaded with steel shavings sludge. I read stories from other Leaf owners that thought was it makes most of the metal in the first 5,000 miles. I bought a new Nissan in 1973 and after 600 mi they drained the motor oil the transmission and the differential .

Have you downloaded Leaf Spy Pro to monitor your battery pack? I really use it often. Our 30 kWh pack triggered the battery warranty at 25K miles and we have put 17K miles on the new 40 kWh pack from Nissan.

Best of success.

If you search for "Nissan Matic-S Automatic Transmission Fluid" on Amazon, you don't get any matches or you don't get any matches that can ship to you directly?

Here is what I found if you want the real deal.

Re: How To: Reduction Gear Oil Change

@gale
Thanks for the input on ATF. Not downloaded Leaf Spy. Car has 70k miles and 11 battery bars (24kwh) so think we’re about as good as we can be. And being a new EV owner I already have minor range anxiety while I get used to the small range so constantly checking my battery health won’t help with that :D

@knightmb
Both your links say “currently unavailable” when I click through hence I’m looking for an alternative.

@bobkart
Thanks for your suggestions. I will check these out. Looking for a middle ground between value and quality.
I usually rate castrol and they do a Dex VI but it’s £28/litre and I’m not wanting to pay that much.

They show in stock for me, so my guess is Amazon is restricting by location then. :(
