Question help diagnose hurth gearbox problem

Hi Everyone.

I am hoping that a gearbox expert might be able to help me diagnose what might be going on with my Hurth 150.

After the gearbox has sat in neutral for several days (weeks?), when I shift it into either forward or reverse there is a hellish amount of grinding noises that bellow forth from the engine compartment. This god awful racket seems to clear up and go away after 5-10 seconds at which point everything seems to work fine.

I have committed several Hurth no nos in my 10 years of ownership. I have left the gearbox in forward while sailing across most of the pacific, I have let the gearbox sit for year long periods without filling it full of ATF, and I have discovered it at one point seeming to lack any ATF at all in it. Having a few months ago filled it properly, it does not seem to be loosing ATF at any great rate at least.

Any idea about why the thing grinds and then seems to clear up?

Much appreciated.
