Nissan australia trying to bend me over

Hows it going guys,

I have a 2008 GU VI 3.0L CRD with just under 93,000 on the clock,
So far the vehicle has been into Nissan to have the: exhaust manifold, turbo,tensioner pulley and dash replaced under warranty. At the moment they have the vehicle in for the gearbox that has been grinding when upshifting from 3rd to 4th and downshifting from 5th to 4th. ( sounds like a syncro to me)

Nissan Australia has decided not to cover the repairs under warranty as they believe the damage has occurred by driving the car like a race car and excessive towing.

Firstly has anyone had any dramas with their gearboxes on these models. I am trying to workout if this is a common problem so I can argue my point with Nissan.

I am heading down to the contractor that has the box to have a look for myself, before the fight begins.

I will update this space as I hear more.
