Just picked up a scoob and it seems to slightly catch when changing into third. The gearbox was recently rebuilt, Im just wondering wether something was missed or if it could be something to do with the clutch.

The gearbox itself feels nice and tight, changes are very nice and not at all sloppy.

Any ideas?

EDIT : Done a bit of searching about and see that it may be worth changing the gearboc oil to Syntrax. Do i need a specific type and does anyone know where i can get it in southampton?
