...mean the box needs replacing? When you hear a whine coming from the gearbox in 4th & 5th gear in an 1984 petrol, Renault Traffic T1200 with 66000mls on the clock. does it mean the gear box needs replacing strait away or will it keeping on running without problems. And if it does need replacing how much would that normally cost for the parts and the work. how many hours will it take to replace a gearbox in that van.
