So it's nothing new everyone knows about the 3rd and 5th gear grinding noise the transmission makes and there's nothing out there to build these transmission but I was just curious is anyone's seen or heard about this

OS giken gears have been out for years.. that price is only for 1st gear though.. not the whole kit.. the whole kit I believe is more like $4-5k

 

you will spend more money rebuilding it, than you would buying a cd009 from Z1

 

Here's my standard advice for syncro problems. If you haven't done so, change the tranny fluid over to Redline MT85. It's a synthetic lube with just enough friction engineered in to allow the syncros to work properly. It also matches the viscocity requirements Nissan has published for our trannys.

 

But if I buy the kit. Does it makes it stronger than a c009. I'm just trying to understand I've built tons of Hondas/acuras and know just about anything possible. And I just bought a 04 350z and wanna start building it just wanna make sure the transmission can hold.

 

you would be an idiot to spend so much on rebuilding vs buying a new one for less
