how do i drain and refill the gearbox on my peugeot boxer 2.2 hdi 2005. Doesnt seem to be a level plug.Can only assume it is filled with a pre-determined amount.Any help greatly appreciated.
there is no filler plug only a drain plug. drain it all out and put 2 litres of gear oil in through the breather on top of gearbox. little black cap sticking out, remove cap and fill.
