35 --- Transmission noise
Bearing or bushes worn or damaged. Renew the affected components.
Gear pinions worn or chipped. Renew the gear pinions.
Metal chips jammed in gear teeth. This can occur when pieces of metal from any failed component are picked up by a meshing pinion. The condition will lead to rapid bearing wear or early gear failure.
Oil level too low. Top up immediately to prevent damage to gearbox.
Gearchange mechanism worn or damaged. Wear or failure of certain items in the selection and change components can induce mis-selection of gears, see Section 27, where incipient engagement of more than one gear set is promoted. Remedial action, by the overhaul of the gearbox, should be taken without delay.
