I finally fashioned a tool out of a 1-1/4" socket (32mm works too) to remove the output flange and figure out why it spins free. I read about the nut coming loose ruining the splines but that's not the case here, at least it doesn't seem to be the case. it might have been a previous failure but I doubt it. The nut was on but good, no fore-aft play in the output flange. So, I removed the output flange and the tail housing. That plastic thing was loose but it's obvious where it fits. It snapped back into place. I thought about replacing parts but I put things back together for the night so as not to lose track of bits and pieces. Now the selector moves between P and R only. I guess I'm shopping for another transmission :/









Can I widen my search to include a 722.315 then swap in the .303 trigger wheel and tail housing?
