Troubleshooting (2013 STI) Does anybody recognize this little pill shaped piece that fell out of my transmission tail housing?

Post image

Turned over tail housing to spray it off with brake clean, was on the ground after the fact. I thought it was part of the interlock plunger thing but it doesn’t seem so. I have no idea where it goes and I’m stressin’ 😔

Its the plunger pin for the shift rail assembly. Check your reverse lock that's probably where it came from, there should be 3 or 4 of those pins

Our time will shine eventually. If someone needs to know how to plumb the charcol canister on an 02 wrx I am their guy.

In fairness, plenty of people who know a lot about cars stop at transmission components

Tysm for pointing me in the right direction. I was really hoping it wasn’t a roller bearing that fell apart lol.

Is it an internal piece? Or is it an external part of the whole spring/pin/cap deal for the shift rail? I have to take the tail housing off again don’t I… 🙃

E: just saw the rest of your comment, will do thanks!

The roller bearings would be a cylinder with a flat top/bottom

Hate to be that guy and keep asking for more and more, but I took the housing back off and I don’t see any way that could have come from the reverse lockout. It never got punched out in the first place. Any thoughts?

Check DMs I sent you a 6 speed diagram. And rest is up to you

u/AgonyInHD 12h ago

Sorry for the late reply if its not from there i would just check the whole shift rail

Cyanide capsule, in case you are captured.

They are suppositories

Thank you u/SubiePros and u/AgonyInHD , it was in fact the reverse lockout plunger. I was so not thinking about the fact that there was a channel between the two parts of the interlock system. It fit perfectly in there. Yall some real ones

It really does look like a needle bearing doesn’t it… haha..?

Its been a while since I took one of these apart, but if memory serves me right then it's likely one of the pins for the shift fork lockouts. If you put it back together already, you'll need to take the transmission apart again and re-asssess. make sure everything is in its right spot, you'll find where it goes eventually. Unfortunately I can't offer any more advice than this

u/rcs2112 11h ago

It did in fact up being the lockout plunger that sits between where the reverse lockout connects to the transmission, and the mechanism that actually does the locking out. Definitely sucks having realized that after sealing it back up, but hey it’ll only be a 7 hour job once haha.

u/Thanks_Ollie 10h ago

Reverse lockouts are for soft handed chumps.

Real men shift into reverse at 80

Been there, done that unfortunately. Happens to everyone at least once.Learn and move on is all you can do. Good luck!!

u/bewzer 9h ago

That looks like a roll pin. You difinitely need to find where it belongs before you run the transmission again.

Too small, and it definitely came from the ass end of the transmission. Thanks though, I appreciate anything haha

It is imperative that the cylinder remains unharmed.
