BW6 gearbox, Bukh DV20, stuck in fwd

Hi, my gearbox is stuck in fwd. I know it’s not the cable, the selector at the gearbox is definitely stuck. Discovered next to no gearboxoil, put in new oil - 0.4 litres as per manual, but not even showing up on dipstick, so about to add more till it shows up/come out overflow - whichever comes first! From some forum surfing I suspect the The cone is stuck to the fwd gear due lack of oil... my questions?
1. Where will the oil I’ve added have gone?
2. How likely is it I’ll get lucky and free it or will I do damage if I bang it with a ‘persuader’ ie hammer ?
3. If I’m really up the **** does anyone know how much distance I’d need to slide the gearbox away from the engine to remove it?
Thanks 🙂

Alsi :
Yes, I suspect the internal mechanism has stuck due to the lack of oil.
You might try a very light tapping on the selector lever to try to free it. It might just work, but tap lightly.
To remove the box, you will have to disconnect the final drive (of course) and remove the final drive coupling, them slide the propshaft as far aft as it will go.
There should be enough clearance to disconnect the box mounting bolts and remove the box.
As regards the oil level, that is puzzling. A call to Bukh would be in order, methinks.
