It's got a regular wet plate clutch. 5 friction discs. Foot shift.
Pulled it apart, everything looks great, nothing missing, nothing broken, nothing stripped. reassembled according to the diagram. Came apart easy, went back together easy.
Only have second gear. Sometimes first.
Seems like clutch isn't releasing enough to engage, and it seems like the clutch is releasing too much to engage.
It's a fucken mystery to me.
