Common gearbox problems and diagnosis

Noise is the first warning sign of a transmission problem. The sooner the problem is caught and repaired, the better: fewer parts will be affected and any repairs will be less expensive. Bearing, gear and shaft wear are the most common causes of noise. As gear tooth faces and bearing races wear, they develop groves and small pits.
