Something inside my transmission wanted to pop out and say hi, what is it?
As the title states something inside my transmission broke out the casting on the 5th/reverse housing on my transmission and I can't identify what it is looking in my manuals.
It happened during an auto-x run and I did another run before noticing the oil leaking out from the hole in the transmission. Transmission still works and I drove to dinner and home. Transmission did have 5th gear grind; I kept it in 4th since this incident, didn't try 5th.
Anyone know what the metal rod in this part of the casting is that broke through the casting right here in front of the oil fill plug?

Not sure what that would be, but regardless that's called Time for a New Transmission.
It's by no means a common failure at least. Get a JDM trans, swap it out, and you're done.

Yes, of course it is time for a new transmission as you say.
I haven't been able to find a transmission yet close enough that I can get to me without paying $500+ (with bellhousing removal) in shipping or drive to pick up in order to get it in time to swap it out this weekend so that it is ready for my next race.
Or I could pay $1,000 through a wrecker to get an unknown quality used trans in time.
I guess I should pull the extension housing and the 5th/rev housing and check it out!
Maybe I could get away with gutting 5th or whatever parts it is I need to get out of the housing. That way whatever that is doesn't come lose and cause mayhem. Sealing the case where the puncture is the easy part.
I do have a spare S5 TII JDM trans I might be able to rob the 5th/reverse housing off if it is compatible as it appears to be.
I wasn't able to find a part # for a complete new FD trans through MazdaSpeed- does such a thing exist?

You sure you didn't run over something that jab the hole into the transmission? A piece of rebar stuck in the ground perhaps? There is nothing in that part of the transmission that could create force enough to punch out the side of that housing and certainly nothing if the transmission continues to work properly.

Yes, it is the metal rod/pin that is in that casting boss that got kicked 45 degrees sideways and punched through the case. It is still in there and I can push it in a little and spin it, but not pull it out.

I am way up in Northern California near Eureka, CA.
I will drive within a roughly 400 mile radius on Friday 9-27-13 to pick a transmission up if someone has one for sale in Northern CA or Oregon or Southern WA.
I put wanted add in NW and West section.

there is a part number for the FD trans, although i'm at work and can't look it up in the BOOK.
we used to yell at Mazda because they have warehouses full of parts that aren't in the parts catalog...

Too weird. Regardless, I do believe you can swap the S5 intermediate housing with the FD. You will need to disassemble that and see what failed. That may be your bigger problem when it comes to the parts you will need to get back on the track.
Yes, I agree it will probably be opening a can of worms if I get the trans apart and really see what happened. I hope I can find a replacement trans instead.
does reverse work? there is the reverse idler shaft in there, but i've never seen one angry enough to try to quit without 2 weeks of notice.
Reverse does work as well as 1st-4th and I haven't been brave enough to try 5th yet.
I thought of the reverse idler shaft as well, but it looks to be at least 1/2" diameter and this little pin is maybe 1/4" at most. It does just look like a locating dowel. Perhaps something larger knocked into the case right there and pushed the dowel out sideways.
I can see now that like getgone said, there isn't room in the case for something to rotate on this pin like a shaft as the casting boss is right there on the surface.

If you can find that part # tonight it would be bad ***. If it is halfway reasonable like the '09-'11 RX-8 6 speed for $2,000 and in the US already I might go that route.
Its probably $5,000+ knowing Mazda pricing for old parts.
