So no warning signs at all re: the trans? I have heard of the issue but don't know too much about it.

I’m at 24k miles, no mechanical issues at all, transmission is working well, although most that have popped were not experiencing an issues beforehand.

Great to know your Miata has been trouble-free so far but wondering the same thing, that's a bit unnerving!

It’s hard to determine why and when and to whom. Most of the transmissions that have blown up were Clubs, modified to some extent, and autox or tracked. I. Say most because some have reported never autox or tracked and were unmodified. Most just got bang with no notice, no funny nosie, no hard shifting....just boom! Mileage has not mattered, some were 20k one I know of was 64k miles. I’m concerned that some of the issues were related to the driver and they’re “style” of driving/shifting. I’m at 25k now who knows...😬..let’s face it, they shaved a whole lot of weight from the car, some of it came out of the tranny as well! 😉

Interesting...Do you know if this affects all ND years so far or have they made changes to the transmission?

It has effected 16-18, in 19 they went to a dual mass flywheel and rev #5 of the tranny, I’ve not heard of any 19‘s or 20’s detonating.
savagegeese has an interview with Dave Coleman Miata Designer and he explains how they didn’t break any during the testing of the ND. As soon as they got on the track as cup cars, many explosions.
I think because mazda made this tranny in house they may have missed an essential design or manufacturing piece and the revisions have not solved it up and until 19/20.

Fascinating and good to know...Do you know if the auto transmissions have suffered a similar fate? Granted I'm not sure how many people track Miatas with auto transmissions.

Not an issue for the automatic. The auto did have a recall for a sudden down shift, but the was an easy reprogram of the ecm.

finished detailing the engine bay. honestly it wasn't that bad...even after driving it for 5 months were it normally would be stored, driving in NC and FL did it no harm. looks like I drove for a while with a small nail in my drivers front Direzza. very slow leak but I cant patch it, its to close to the edge of the tire wall.

Thanks for the quick explanation of the trans issues. A little unnerving if you are an owner, just waiting to see if it goes or not.

Engine bay looks great...as always. :p Sorry to hear you can't fix the tire. Sticking with the Direzza's or going another route?

not sure....i like them, but the road noise of directional tires as they wear is almost unbearable on the highway...but they sure are sticky
