transit 5th gear only?

Is it FWD? Look at the top of the selector mechanism on top of the gearbox,in there are needle roller bearings which are bad for seizing,spray with WD40 where the shaft enters the g/box and work back and forth,apply oil/spray grease when it eases off,they normally free off eventually. If not then the selector mechanism is very expensive,you could try a scrappy for a used unit.
