LT77 Gearbox cant get into gear

Hi guys,

So, got the defender back today! But i know it had been standing, not for too long, but long enough to know things will need changing as it goes back into use...

Now when i started back all was good, until i went to find 3rd gear

So the problem is, it wont go into 3rd, or 4th... the stick wont move up or down, but im getting 1st and 2nd fine, but 5th has a slight crunch

Could anyone suggest what i need to do, or even if its a gearbox out job/gearbox change.

Any help would be appreciated. :tea:

is it that your not finding 3rd/4th alignment or does it feel like you are but synchro hub is jammed

it honestly feels like its in the right place, just wont go in
