Default Help! Found this piece of metal attached to the tranny drain plug. Pics!

It appears to be a woodruff key. Any help is appreciated. I was draining the tranny prior to pulling it to replace the clutch and trace down a popping out of fifth gear problem(think thats related to a loose main shaft nut.)

Looks to me like an insert from a syncro assembly. I've not done a Subaru trans. but in the ones I have done there would be 3 of these inserts guiding the syncro slider over the hub.
Hope I am wrong

Agrees with mike, to some its called a shift strut. Goes in the syncro assy.

That sounds feasible. I am getting a crunching sound going into fifth and fifth is popping out of gear. I have been told my fifth gear syncro could be bad based on that behavior. Thing thats confusing to me is how this part could have migrated from its theoretical position(if its part of the 5th gear syncro assembly) at the rear of the main shaft to under the front diff.

Could it also be called a "shifting insert key"?

Thats what it is. I've only done toyota and vw transmissions but the basic manual design is all the same. About the only way for that key to get out is by the selector sleeve or slider(or what ever subaru calls theirs) is over traveling and letting the key pop out.

I think the OP has a bent fork. You're lucky it made it to the drain but you have two more the may pop out of that syncro assembly.

32613AA041 Insert Shifting. Thats what subaruparts.com calls the key in the picture.


I just saw the mention of the loose main shaft nut. That could be the reason for the over travel also.

GDR do you have a link to the picture you are looking at on subaruparts.com? Do you think it would be possible for me to put it back wherever it came out of or is the syncro shot in some way now?

Thanks guys

Paco - thanks for offer, PMed you back.

GDR thanks for the PM.

Here's the blowup GDR was referring to, its for the 02 WRX tranny but its likely very similar to mine.

I am guessing even though they dont show all three, there are three of these inserts at each syncro?

Update:

I finished pulling apart the tranny today and when I broke the rear section(center diff housing) loose from the main tranny, out fell the other two shift inserts like the one pictured above. When I split the main tranny housing and inspected the main shaft nut, it was staked correctly and doesnt appear to have moved. I also am at a loss to see where from and how these pieces fell out. I am guessing cycling the gears opens different gaps along the shaft and maybe in its current setting I cant see the part these would come from.

take the tranny and shift it into 5th gear. You may be able to see where those pieces fell out from.
oh yea....MORE PICS.

I will do it if you can tell me how to shift it. The linkage and the shift rod are removed and this thing looks like Greek to me.

PICS! The first one is pretty big for detail.

They are still there, but if they were originally as wide as the channel in the coupling sleeve, theyre worn. Theyre approximately the width of the metal portion of the shifter fork that holds them.

ss

One more pic same as above but rotated(same orientation as the tech manual now I think) and reduced in size.

Gonna need a new fork. Without the plastic pieces you can see on the 3/4 and 1/2 forks, the selecter slider won't be held secure and won't slide evenly if one side or the other is missing. I would think this would cause the inserts to come out. I think you've found your problem. Might replace the 5th syncro also as it has probably been hurt from this.

Bottom pad doesn't look very happy. Do you see any cracks in the fork radius?

What acts as a shift stop? If it's worn could the slider overtravel enough to pop an insert?

The nylon inserts are there(dont know if theyre showing up well in the pics) but they are worn particularly if they were wider new.

No visible cracks in the fork itself.

The 5th/rev coupling sleeve slid right off, the inserts are definitely from under there. The first baulk ring between the 5th/rev syncro hub and the 5th driven gear is fairly loose(will twist a bit on the shaft.) The second is fairly tight. I appears there is some sort of wire spring applying pressure from inside the syncro ring on the underside of these inserts.

More pics coming.

Boss, I don't see any nylon on there at all??? Look at your 1st/2nd fork and compare how much it has to the 5th/rev.

I got the inserts(kinda a pita, need 3 hands) back into the syncro and it feels largely functional now(similar to the others.) It would have been easier if I had the manual for my tranny, the manual I have has some differences at key points but I sorted it out.

Pic of the syncro hub:


Andrew, yea youre right, just remnants of nylon at the sides.

I calipered the channel at a shade over 8mm, the metal portion of the 5th/rev fork at 5-5.5mm and the pads on the other forks at 7-7.5mm.

I think theres a combo of things wrong here but the pads are definitely part of it.

Pads on the 5th/rev fork worn/gone
general wear down the shaft allowing more slack

Im gonna try this and see what happens.

Replace the shifter fork
Replace the the main shaft nut and retorque and stake.
Hope the 5th syncro is ok, its only available as a piece of a series of parts which cost right at $200(I can get a used lower mileage tranny for $500.)

Seem feasible?
