Help got a boxer gearbox with no oil in it anyone know where the level and fill plugs are its ( p ) reg and a 2.5 non turbo 5 speed cheers Rick

Don't know about the Boxer but most peugeots filler bungs are in the end of the gearbox furthest from the flywheel. Usually an 8mm square hole in the bung?

I'm sure the fill/level plug and also the drain plug are on the diff casing
