Hi guy/girls

I have a 1.6 twinport 06plate

I think im having a bit of problem with ever my gearbox or gear link,

Never had this problem with any other of my cars

when I start it up I 9/10 levee it running for about 1min or 2 be for I drive any were, as I park in front of my garage I have to reverse, but when I select reveres is crunches the box no matter how fair I push the clutch down??

Could this be a gear link problem???
