Hi all, nice to meet you people,

I am coming to you guys with a questions regarding my 09 RX-8 R3. As you may already know, the 09 RX-8s have some issue with their transmissions, and sadly mine has gone to ****. By that I mean that my 3rd and 4th gears are simply MIA, sometimes I am able to get it into 3rd and it's not poping out, but that's only if I'm really lucky, and 4th is simply gone.
I've looked all of the place for a manual trans for an 09 but I am unable to find one. I did find some all the way in the US, but since I'm in Romania, shipping one is not worth it, as I'm better off getting a scrap R3 from UK and just the trans from that since it's cheaper. I was able to find loads of 6 speed manual trans from previous generations, but I am unable to find anywhere on the internet information about it fitting my R3 or not.

Does anybody know if I will be able to fit a 6 speed trans from a previous gen on my R3? And if Yes, what modifications will I need to make if any. Thanks in advance.

 

You can fit S2 transes into an S1 so I believe it's doable. The shifter is different so you'll need an S1 shifter if it doesn't come with one. Otherwise I can't think of why it wouldn't work.

 

Isn't there a procedure to realign the shifter system to stop the pop out on 3rd and 4th?

 

Try this one:

Not sure this applies to my issue, my never popped out. It used to make grinding noises when driving it hard and trying to get into either 3rd or 4th. At the moment, I can't get it to go in to 4th at all while 3rd sometimes goes in and stays in.

 

Not sure this applies to me, as I can't get it into gear anymore. To be fair, mine was never popping out of gear, it was something griding when trying to put it into 3rd or 4th while driving hard, but never popped out

 

it bolts directly in.

the only issue is the reverse and neutral switch connectors are different. They’re just two-wire 5 Volt connecters though. So you can just cut the connectors off the S2 trans and rewire them onto the S1 trans. Or put any two-wire connector set you want there.

other than it maybe being less durable, the S1 trans is a better match for the S2 4.77 rear gear. 3rd gear especially is a much better ratio.

good luck

 

Awesome reply, pretty much answered everything I needed to know.
I've just ordered a trans a few minutes ago, I will be with me in about 2 weeks time.

Thank you again, to you and everyone else that replied!

 

I did forget to mention that 6th gear is a less steep ratio on the S1 transmission. So the cruise rpm will be higher.

That's more than fine, I'm loving the sound the car makes at 5-6000 rpm anyway. Not to mention, as I'm pretty much stuck with getting a s1 trans anyway, can't really complain,.as it's better than what I'm having at the moment

I took the car for a drive around town on Saturday, going from 9000 rpm in 2nd straight to 5th was not much fun lol😊
