I think I would be more worried about the damage done to the rest of the mechanism than the source of the lump of metal...

Good luck

Yes of course, but as a matter of interest...especially as this busted trans doesn't need a quick repair. I have a spare.

Hmmm, I don't think a piece of round kicker spring could be flattened like that?

I was looking at the diagram to try and understand what piece it might be? No conclusion from that exercise. The lever does move more freely is all I'm saying! ;)

Found it! Front bearing on the output shaft, with some gear surface damage to 5th gear and adjacent one on the intermediate shaft.

Some damage to the gear edges...

Ouch! Not a happy outcome but not, I would suggest, totally unexpected. No cigars to anyone for guessing that one.

I know it wasn't on the magnetic plug but is it, in fact, attracted to a magnet. This will tell you if it's steel or... well... not steel which, in the interior of the box, pretty much means aluminium alloy. If it's steel, then it's probably a gear tooth. If not, it is something knocked off the case somewhere... in which case, it is a pretty sure sign of another problem.

In any case, I think it's academic. With the problems you have, I can see no alternative to dismantling the box to see what gives. Once you get in there, you'll find out where the problem is and where to go from there. I would say, though, that the prognosis isn't brilliant. The chance of collateral damage inside the box is quite high and it would be quite a reasonable response to simply source another box.

Actually Rob Frankham was correct. It was all academic until you removed and opened up the trans. And there was collateral damage.
But all this reminds me of an episode of Car Talk (NPR show out of Boston) where it was postulated that:
"two people who don't know what they are talking about know more or less than one person who doesn't know what he's talking about?"

This thread proves it! ;)

My apologies Seth, missed that... I'd send you a cigar but I don't want to damage your health :D

That’s ok.
I don’t drink or smoke anyway.
Never thought it was a contest.
Like most people here, just trying to help out.
