Oil running hot inside causing one of the cogs or bearings to weaken - clutching at straws there though as I don't know too much about gearboxes! (apart from what they do!).

i have noticed the box had been getting a little notchy of late

You can still drive it now ok in a way
Theres no noises/rumbling and it changes fine!

Is the breather blocked causing a pressure build-up on the inside ?? Happened to me at Llandow last year but it blew out the small core plug inside the bellhousing.
