Default M45 Gearbox - Identify part and rebuild question

Upon draining my M45 I was greeted by a part that belongs elsewhere. Can anybody identify this part and what it does/serves?

Also, it appears the 1st gear baulk ring and its retainer clip has come free, can this be repaired without removing the Mainshaft and pinions?

No guarantees, but...

If that is actually the part it seems to be, looks like the baulk ring came loose, and allowed that piece (1 of 3?) to escape from inside the synchronizer assembly, between parts 19 + 23. I think it's disassembly time.

No. 12 looks like the same type of assembly as well. Although 20 does look more like the part in your pic.

did you notice that the input shaft can slide forward without the front case/bellhousing there?
did you pull it forward AND rotate it?
Ask me how I know about this



I was able to get the slide key and wire spring back into place WITHOUT taking the thing apart.
It took about 3 hours and was tedious but it can be done! Good luck!
