Grinding Noise from Gearbox – Causes, Symptoms & Repairs
If you’ve noticed a grinding noise coming from your gearbox, it’s a warning sign that something inside your transmission is worn, damaged, or in need of adjustment. Left untreated, a noisy gearbox can quickly turn into a major repair job, costing far more than early intervention. Our skilled technicians can diagnose the cause of gearbox grinding — whether it’s worn gears, damaged bearings, or low-quality transmission fluid — and carry out precise repairs to restore smooth, quiet performance. We work on all makes and models, from manual gearboxes to advanced automatics.
Common Symptoms of Gearbox Grinding:
