no there is a gate plate under the selector yoke but it doesnt give issues,bushes stiffens lever up or makes it too loose

Ah don't think it's that then. If it were it would be same even with the vehicle stationary mefinks. This is when moving so clutch transfer or gearbox or diff I think I just have no luck with this car what so ever :(
 
James, if the OP has all other gears, if it drives normally in other gears ,most likely a lost synchro spring which holds the 3 slipper pads in place, these rock like seesaw depending on 3rd or 4th selected and hold the synchro in gear...

If spring comes out slipper pads can come out of line jamming that gear only way to fix is to strip box,the only other likely thing is very common where brgs wear out letting input shaft drop putting it out of alignment with mainshaft but would be noisy in all gears and will quickly loose all drive ,if you drop oil you will probably find parts of 10 cm c shaped wire spring ...? idea !

id look at it for you but your a fair way away ,non clearing clutch would effect reverse and 1st ,mtf94 oil can help poor baulk rings

poor bearing in input/mainshaft effects 4th selection only ,synchro spring just jams operation of the gear it will never go in ,but changing outer baulk ring still requires strip down ,the dog teeth on ring wear only allowing selection when synchro and gear line randomly up or you double declutch
 
for the OP ... so he knows what the nasty bits look like :D ;)

If I come to complete stop I let clutch in it won't go to first or second, let clutch out in neutral press it in then it selects first fine.
If driving in third but only with third if go on and off with the gas pedal can feel the lever move as if the gearbox is moving but fourth and fifth doesn't do this.
First to second changes okish although at one point between changing first to second the moment clutch was pressed in there was a rumble knock underneath but shifted to second it stopped and hasn't done it since. But now always in reverse whether clutch in or not it doesn't like it. To me it feels like something is being chewed up. Like when you have a broken brake pad and the car tries to lift on its suspension as its trying to turn a locked wheel? Clutch in on a hill, reverse engaged, brakes off it was solid like handbrake was on. If in neautral on hill and brakes off it rolls back freely but if in reverse even with clutch pedal as far down as the floor it doesn't want to know

Welcome to the Landy Ladies - :cool: -there are a few of us now :D

gearboxes are easy - it's getting to them that's a bastid ... and messy

that's why they're expensive to do - time to get to the 'bit' that dunt work ...

The first bit of your post sounds like double declutching -

have you tried that in all the gears ?
 
Just an update to follow this up..

I took the car to my local garage (the ONLY person I trust my car with as he served his apprenticeship with Land Rover and he knows them inside out) and it turns out I had somehow managed to destroy most of the internals of the box, it was a mess inside! I was given a choice either exchange it for a recon box for 850 or rebuild it for 680. I chose to have it rebuilt and it has NEVER been soo good!
When I set off from the garage in first it was fine but when I went to shift to second there was no feeling of it going in! Same with rest of the gears it is SO SILKY SMOOTH its a joy! And no more do I have to clutch in and out a few times before I can get reverse either it goes in first time every time.
It cost a lot of money (my car always does lol) but money well spent I love that gearbox now its fantastic! ^_^
