Not sure what you mean by "not quite solidly into one gear or
another." Does it happen at idle?

Probably not an idle issue. Please clarify what effect shifting has
on this.

Prob not a valve lash problem.

You're closer; you'll have to tell us. Get a long screwdriver and
stick it against various parts of the engine with the blunt end in
your ear. Pin down the area where the noise is coming from.

Probably not. My first guess is that the 2 screws that attach the fan
housing to the engine case have come loose. They are now rattling
against the fan. I don't know why that noise would go away under some
conditions, however.
