hi all. just wanted to ask a quick question. a mate has just bought a disco 200tdi on a k plate. now when he bought it he was told that it sometimes would jump out of gear on the motorway. he should pull over and re tighten a shaft or nut on the gearbox and he would be able to carry on. thing is he has no idea where this is.....i know this all sounds very vauge but im hoping that someone will know what he was on about :? .
any help would be brilliant...
cheers in advance. oh its a manual gearbox
