Understand Car Transmission Sounds to Avoid Costly Repairs

The transmission is your car"s central nervous system for power delivery, a complex labyrinth of gears, bearings, and hydraulic circuits. When it"s healthy, its operation is a seamless, silent transition. But when problems arise, it communicates through a distinct vocabulary of whines, grinds, and clunks. Misinterpreting—or ignoring—these sounds can lead from a simple fix to a catastrophic, multi-thousand-dollar repair. Learning this language is key to preserving one of your vehicle"s most expensive components.
