Here’s the Transmission Update on my 2023 Miata!

Welcome back guys! Here’s my 2023 Mazda M-5 Miata Club! Its recently had its 6 speed manual transmission replaced due to the 3rd and 4th gear brass synchros failures.

I believe Mazda had issues with supply of the factory fill OEM fitted “Long Life Gear Oil IS”transmission oil manufactured by Idemitsu
I live in the U.K. and have a 2023 Homura. At 3500miles I fitted Redline MT90 GL-4 being renowned as perfect for the ND 6 speed box offering better cold performance, quicker shifts, perfect synchroniser coefficient of friction, and being Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause corrosive damage to the synchronisers

The Club version of the soft top Miata is slightly over $38k before the government’s charges. Probably another $4k here in CA. That ND3 is sure pretty but I think I’ll hang on to my NC1 for now, it’s got 190k miles and still runs great.

My 2023 1.5RF had the third gear synchro fail at 4200 miles. Mazda know all about it but won't admit it. I waited about 4 weeks for a warranty gearbox to arrive but gave up in the end and sold the car back to the dealership

I had a throw out bearing go out on a pickup, but didn’t realize it until the clutch went out, so as I was saving the money, I drove the truck clutchless for a couple of weeks. When the engine RPM matches the rotation of the transmission, you can easily slip it into the gear that you need to.
When you come to a stop, put the transmission in neutral and when you need to get going, put the transmission into first gear and let the starter get it going. It’s hard on the starter, but if you’re in a pinch, you make do with what you have .

I was concerned about the issues raised re the manual transmission on the 2023 Miata, since I own one. I drive it regularly but not frequently as I also have a Camry as my daily. So far this has not been an issue at all. My local dealer service manage who I’ve know for years says she has not seen this issue about the 3rd gear problems or any problems like you described. Moreover with a 5 year power train warrant it would totally covered. So I feel pretty good. This manual has not given me any problems so far and if it does I’ll get it fixed under warranty. Only a year so far with low miles. I’m not going to use it as my daily anyway so no problem at all.

As an ND2 owner myself and also having driven many cars, I completely agree with your opinion on how amazing of a car this is 😊

Mine is in for it's 2nd transmission in just 24, 000 miles. Same 3rd/4th synchro issue.

Very good video. So glad you talk with video on the car. Car videos of a guys face kills me when I just want to see the car and listen. White looks great on the MX-5.

Yeah warranty covers it happened to my cx3

I just bought a 2023 grand touring with just 3200 miles yesterday from a private seller. I drove it home 360 miles but highway driving 5th and 6th mostly. Today I drove it for 40 minutes and half way though, the 3rd gear was hard to get into. Feels like synchros.

Mine is in for a new transmission too. 2023 I agree it’s a fantastic car

There's an interesting thing i learned on a recent trip to the dealership... Apparently 19 to 21 miatas have a special transmission fluid... This isn't, apparently, a mazda transmission fluid and as a result the trans flush is quite expensive on those cars... 22 and up have relatively more standard mazda gear oils ... Wonder if this has something to do with what you're seeing here....

[patrickstover]

I have a '23 soft top grand touring I bought new last year. I am concerned about this, but honestly if the transmission fails, even after the warranty is up, I'll pay to replace it because the driving is bliss.

[PaulHojda]

my 2023 1.5l is still waiting on it's new transmission. Same synchro problem with 3rd gear. eta on a new transmission is two months😢

[fahmidnd]

mine did, do a fluid change after 2000miles just watch the silver come out. i put in ford motorcraft 'unicorn tears', it shifts so much better. FOR NOW.

[techne]

I have a problem with my 2024 with it whining. Can I ask where the tow hooks came from or what brand?

[realaveragegamer]

Did you just double clutch till it got fixed?

my 2nd gear synchro went out in my s2k and it was a pain in the ass

[michaelfishkin]

Have they determined what is causing it so it is not a repeat problem?

[jameschan]

had the same exact problem, 2nd gearbox breaking 💀💀💀 Dealer said no other case in North America 💀💀💀💀

[Masatao]

Is it the same transmission in the 2024?
