What gearbox issue 
Sloppier than one of Sir Tigs' Marina conquests. And cannot select 1st when cold (and even when warm, tend to have to put in 2nd before selecting 1st)
clutch dragging.
Is it cable or hydraulic.?
F23 box with Concentric Slave Cylinder ,hydraulic
shares the brake fluid reservoir i'd think
probably not been bled or seen fresh fluid since new
not got the haynes here

(in the car) so will check when i get chance.
plus see where the drain and fill/level plugs are on the gearbox
may require fluid to work

you can get an insert for the shifter and bushes gearbox end I think (for the sloppy select)
