common fault mate, mine as done it for 2 years, i just change into 5th gently and slowly and it doesnt crunch

Mine does that, if you dip the clutch and lower the revs it goes in no issue, I would like to know of it can be fixed, was going to get another box but that may have the same issue, My box has done 69,000 and had an fairly easy life

I think there is a nut that comes loose on one of the shafts that can cause the problem abut i have forgoten the exact details.

Try changing the box oil for a descent oil and see if that helps

There was a known fault with a nut in the gearbox that wasnt torqued up as well as it should have been at the factory, you have been lucky its lasted 13 years, easy fix if you get it sorted now, wait and it will probably cost you a new gearbox
