I was just getting ready to do this for my 2020 nd next weekend - thanks for uploading the video, good to know it's approximately as simple as I was expecting.
Thanks for posting this video - I just picked up a 2020 GT and have been thinking about switching the manual trans oil out. It's got 7400 miles on it but I'm not a fan of how it's switching gears right now.
Check out my follow up video showing the oil analysis by Blackstone: ruclips.net/video/rMKOZPSNo4w/видео.html My takeaway is that it is probably a good idea to change the fluid out based on the time service interval. I didn't notice a huge difference shifting with the fresh oil but I used OEM fluid. The ND transmission is notchy and all manuals can have quirks like being difficult to shift into 1st in certain situations. My 2023 Honda Civic is actually way worse than my ND when it comes to not shifting into 1st or 2nd, I've gotten caught out at lights multiple times in the Civic because it refuses to go into 1st gear - this is common based on what I find other owners saying online.
@@Moriggia There is no service interval for it. It is documented in the service manual as part of the transmission replacement process - a brand new transmission needs the turret filled. I have seen people change it at the 25k mile mark and it looks basically brand new (compared to the black oil I pulled out at 25k miles). I wouldn't worry about it unless you are tracking your car.
There is no specified interval that I am aware of. The oil in the turret is not seeing the heat or shearing that the oil in the gearbox sees so unless it leaks or you disassemble the transmission (per the shop manual www.hexorcism.com/16ND/sm353149/) it isn't necessary to address.
Mazda sells quarts, 2.11 quarts = 2.0 liters. You need 3 quarts from Mazda to fill the transmission and 90% of the third quart won't be used. Very annoying, I know.
@@Moriggia Can't say what the impact would be. You're just slightly more than 5% off the required fill. Personally, knowing the ND transmission is a weak point of the car, I would try to correct this when you have the chance but I wouldn't say it is urgent unless you are tracking / autocrossing it.
This can be accounted for, you can see that I turned the crowfoot 90 degrees to the wrench handle: www.tekton.com/blog/how-to-accurately-use-a-torque-wrench-with-a-crowfoot-wrench
Can I borrow your lift?
Proudly displaying how you skinned your knuckles, you get a like for that.

I would recommend a medium length 3/8” breaker bar and shallow sockets to crack the 24/23mm drain and fill plugs on both gearbox & differential……
A little bit tougher on jack stands but I did this last year. The magnetic drain plug looked about the same as yours did on a 2016 Club model.
Great straightforward video. I'm laughing at 3:00 though haha, the miata demands a blood sacrifice

Hi, thanks for the great video!
By chance, do you know if the replacement is the same for automatic transmission?
The replacement is different for an automatic, I believe I linked to the shop manual for it in another comment.
Nice presentation. Would same procedure apply for automatic transmission on same car?

Hello, does this transmission has turret oil separate from the gearbox? Thank you
It does. I did not change it during this process.
@@paulgaecke9055 I don't find videos on youtube LoL I was just curious.

@@paulgaecke9055 I agree with you, that oil isn't stressed.
4:30 what is your exhaust set up? TIA
Stock exhaust except for a Good-Win-Racing RoadsterSport SuperStreet axle back:

Is it recommended to replace the oil in turret ?
There is no specified interval that I am aware of. The oil in the turret is not seeing the heat or shearing that the oil in the gearbox sees so unless it leaks or you disassemble the transmission (per the shop manual www.hexorcism.com/16ND/sm353149/) it isn't necessary to address.
It seems more than 2 liters of the manual right?

@@paulgaecke9055 ah ok, I bought 2 bottles of Redline, 946 ml X2=1892ml, I don't know if it changes much.

@@paulgaecke9055 you are right, I think I will fix this issue :)
The torque wrench with the lateral extension gives a wrong torque.
