thesnowboarder just broke one.
Bob, parts are cheap. I paid $360 in labor and $250 in parts to have my 5/R shift fork, selector, reverse synchro and gear replaced over the winter. Open it up and have it looked at before something goes really bad and wrecks multiple gears.
Sounds like I need to find a spare gearbox.

Downshifted to 4th and it let go. He hasn't opened it yet.
Jay, nobody makes/builds a stronger 6-speed box except the MSM boxes with the shotpeened gears. TSB is the first one I know of to fail during road course use. My box looked perfect when I had it open. If I do start breaking stuff, just start filling it with MSM gears.
If the gearbox lasts 2 years at these power levels, that's acceptable to me.

I should have the new motor in with the 6 speed in a couple weeks, tranny should be broken not long after that I imagine lol.
On a side note, none of my 5 speeds made any noises before breaking.

I have 16-hours on my 6-speed at 250whp and although I haven't had the best lap times in the world, the car is driven like a warrior. I have no symptoms or noises of any kind.
I also have a metal clutch...which needs to come to an end. TheSnowboardingQueer also had about 300whp if not more going through the trans too.

My 6 speed is making rattly gear stripping noises at high revs in second and 3rd gear maybe 4th too.
The 5 speeds I have broken 3 different ways. Stripping second or third was just a loud bang at full acceleration right about the point in the RPM range where I am making peak torque. The ones I broke the gear that drives the secondary shaft on all would make loud squealing noises on coast down after a hard use for a little while before Kablamo.
I need to get a spare before I take this one out and try and figure out what’s going on.
Dang it, driving a Miata this fast is expensive. I can’t afford some of the upgrades I want if I keep spending so much money keeping it rolling.

I might be interested in that. I need to get a spare first and I got to save up some cash flow first.
I got another 5 speed I can throw in if I have to for a couple weeks if it goes Kaboom.

I guess ill yank it out this week and see what kind of damage happened. To be fair to the transmission, I do not treat is nicely, lots and lots of fast/hard shifts. I can say i never really did a stand still burn out or clutch popping on it though.
