Hello, I have an 07 RX8 GT with the 6 speed manual. I have to rebuild the trans with new synchros and bearings. Just wondering, what is the transmission code and is there a service/overhaul manual for them and what is a good synchro to use? I was reading about carbon fiber ones or something along the lines of that. Also when I am in 3rd, 5th and 6th the trans is louder than all the other gears. Is that normal?

Thanks,
Zac

 

If you can find a good used transmission it will be a lot cheaper...the syncros and crap for these trannies are expensive

AFAIK..there are no carbon syncros for this transmission

 

If you haven't dismantled it yet and are not 100% the tranny is worn out, some new gear oil might make a hell of a difference. It did for me anyways.

 

++1 on both suggestions above

Also the Tranny being loud, check your tranny leather boot its got holes in a few spots that is ususally the reason behind tranny being loud in certain gears.

Cover them up and it will disappear.

 

Yea I had the transmission fluid flushed. And I might do a swap if I can find a series 2 trans. Hear that they are better than te first series. That leather boot though. Where is that located?

 

Around your shifter attached to the top of the trans tunnel

 

is the series 2 trans a direct bolt and plug and play or are their mods that need to be done?

 

Before you get flamed to well done...do a quick search. .... there is a detailed thread on the swap

 

Do you know where that thread is cause ive been looking and cannot find it
