Sounds like the spring for the pawl for the shifter strikes again. I was reading about this before, never had it happen to me. Someone will probably chime in on this for you. Good luck, should be a simple fix.
Ok, I have not dismantled anything on the engine myself, BUT if shark is right, I believe this can be an easy fix.
1- Drop the oil
2- remove the left side external shift mechanism cover (with the oil level sight glass in it). Held by 6 cap screws I believe. Be careful with the gasket, but you will probably need a new one to reassemble.
The pawl is reference #13165 in the diagram in the link above.
the spring is ref.# 92081A
Not sure if the spring is likely to be broken or just fallen off.
I remember reading in an old post that someone built up worn tips on the pawl by welding with a MIG or TIG welder. So check the tips too.
The parts under this cover are the only tranny parts accesible without splitting the engine cases.
I hope it is this spring and not the tie-rod. Much easier repair.
