I zoom therefore I am.
actually the RX8 tranny isn't junk and lots of people have used it with engine mods that far surpass what 99.9% of owners could ever hope to see. I'm not referring to just NoS and daily driving FI, we're talking people who race for more then a hobby.
But hey, this is the internet and people with no real clue about anything can say anything they want just to make a post... maybe i'm one of those people. then again, maybe i'm not.

All in all our trasmission is not bulletproof but after the 5th repair i would doubt who did the rebuild or the driver.
Can't you ask for a new one?

a tranny that can hold under 10,000k and over 150mph is not a POS. Its just that these trannies are asked to hold up under conditions that 90% (out of my a$$) of all transmission on the market could not.
Im sure its a cost/benifit for mazda. Make the tranny bulletproof and up the price by a few thousand. Or make a tranny with a certian fail rate and replace those few.
at your 5th rebuild though I would start taking it to other shops, or if its under warranty demand a whole new unit.

I had the bearings replaced in mine.
A 2009 transmission should swap in no problem. Honestly if you have to come out of pocket for one that would be the way to go.

Fixing these tranny issue is costly "enough" to get Mazda's attention.This is one of the reasons why Mazda has to come up with a new box for 09+
09+ tranny is a direct swap to the older one. no issues.
I drive mine easy. Im at 49K miles now, I change my fluid like every 10-15 K. Thats more than enough for tranny. but starting just 2 months ago when it was cold(around 20-30 degrees), it was impossible to shift into reverse, sometimes not even first. It never happened before. Now its warmer and its getting better. but thats not acceptable to me. and Im going to have them look at it This wednesday or thursday.

Or we could buy the Syncro Saver Kits we sell to prevent issues like this happening and spending hundreds on costly rebuilds and replacements...

the OP isn't slamming the thing into gear or racing the car.

Please do not try to answer questions for something you clearly don't understand.

Excuse me Brice, did you EVER overhaul a transmission?
Slamming the gears is not the only way to damage synchros but, to quote somebody, what do i know?
Now please tell us why the synchros tend to go south too often.

As for me not understanding, quite the contrary. I've had my transmission replaced for bad synchros so I know all about this issue. Besides, I probably have more experience working on cars then you do so don't confuse yourself or others by thinking you are intellectually on the same automotive level as I am, becuase you're not.

OP: to answer your question; NO, everyone does not have problems with their transmission. Early models had problems with the shift forks and Mazda issued a TSB for them.
You mentioned that you weren't racing when it happened...do you race at other times? (either on the street or track, I'm just wondering what kind of use your car gets)
how's your clutch pedal? how's the clutch? what fluids are you running?

Jedi, your force strikes again.
To the OP, could you please be more specific regarding your issues? Like in what gear did the happen and so on? This would really help.

Sorry but i still think the rx8 transmission is a pos. Although i would like to listen to your logic behind why you think its not considered a pos. Just because of marketing reasons? Id rather have a bulletproof tranny then one that costs less. How does the 09+ trannies hold up with FI? Just wondering if i should go this route. :S

636: not sure if that was directed at me or not but I don't think the transmission is a POS.
I'm pretty sure a lot of the transmission replacements that happened in the past were a result of bad clutch pedals and not necessarily bad transmissions.
Just look at all the companies that have tried to fix the pedal. Mazport / Fluid brace, BHR welding, Mazda bracket, etc
Dont' get me wrong, I'd LOVE a bulletproof transmission as well but I've got almost 30k on my 2nd transmission with a welded clutch bracket and it's been perfect.
As for the 09, it's supposed to be a beefier transmission but I don't believe there are sufficient FI cars with that transmission to derive any true data as to it's real potential with added hp. We'll have to wait and see
