Hi all, has anyone else had this problem, the old filler/level plug on my r380 gearbox was knackered the torx drive was chewed up inside, managed to remove it and went to fit the new filler/level plug but the new one screwed in so far it fell inside the gearbox . can anyone tell me if i can retrieve it through the drain plug or is it a gearbox out job. any help would be much appreciated
