6 speed transmission #4 go boom.
This time new failure mode. Stripped second gear instead of 4th this time. Newish 275 A6 hoosiers nice 80 degree day on a super grippy lot. Car was ridiculously fast until that happened near the finish of my first autocross run.
Sure wish somebody would make a proper solution with good gearing for this weak link.

This transmission might have been a little suspect as I built it myself out of two damaged transmissions. The first transmission I broke actually had a thrust retainer failure and the gears were fine on one of the shafts where as a 4th gear strip out takes out the other shaft.

Just finishing up my build and found this post and the other 6 speed post. These two post have me worried and after some research I found this. Seams like a good high HP and T fix. I emailed them and I
Was informed this will fit in the Mazda box. They will even make custom hear ratios. It's a lot cheaper then the Nismo box as well.

" Hi,
Approximate ratings for each,
Dog sets 1000hp, 800Nm
Synchro 800hp, 650Nm.
Are you using the gear set for street driving or purely track use?
Since the transmission is an Aisin the same as used in nissan and mazda certain models besides the input and output shafts the prices can be found on ur site,

I don't know much about it since I haven't had to look into this at my power level but I've heard more than one time about the RX-7 trans mounting up with an adapter plate and handling much more power. Not a good solution? Bad gearing?
