Noises in the gearbox almost always indicate worn gears or shaft bearings. Such noises most often occur in cars with high mileage. In this case, first of all, check the oil level in the gearbox.
If the howling sound occurs only when a certain gear is engaged, the teeth of the corresponding pair of gears are probably worn out.
If noises appear when any gear is engaged, then the cause may be a malfunction of the main gear or the bearings of the gearbox shafts.
A sharp rattle that occurs only when the gearbox warms up indicates a beating of the synchronizer blocking rings.
