gearbox additive ?

Either the synchro is just about done (or there is no oil in the box, in which case it is probably not only the synchro that is just about gone) or the clutch is not disengaging properly, although this would probably (but not necessarily as if I remember rightly this box has synchro on all gears which could hide this problem) also show up when engaging gear from stopped. I can't see adding any additive helping. JD

I've just found out about a Landy Rover mechanic near me who is supposed to be good. He's certainley the closest to me so I will be heading his way at some point in the future.

Bennington Land Rover Centre, Bennington park farm, Bennington, Herts.

this RR actually belonged to the owner of a non franchise landy workshop but was sold off the forecourt of another dealership I will give them a ring and see if it was them? as for the gear box problem it is intermitent and goes away after the vechile has been driven for a while so I am not in any rush ( will tinker a little and see what happens )

vehicle has been driven for a while <

After the oil warms up? Perhaps it has the wrong oil? You might try draining it and using a full synthetic oil. It might be worth a try rather than going straight to a rebuild.

I changed the oil last weekend and it seemed to make the problem worse at first but since then the problem has improved . it supposedly has a new genuine clutch but still sometimes refuses to go into gear say 2nd to third or fith to fourth ! when in neutral operating the clutch doesnt change the engine note mutch so I suspect the selector mechanism especially as when I try to engage low ratio I just get the message "sellect neutral" hmmmm need to learn to go read the workshop manual abit more I think .
