Which car transmission lasts longer?

Manual transmissions are usually more durable than automatic ones, mainly due to their simple structure, fewer mechanical components, and lower maintenance costs. Core components of manual transmissions, such as gear sets, are made of high-strength low-carbon alloy steel. Automatic transmissions rely on torque converters and electronic control systems. Although they reduce mechanical friction, electronic component failures account for 61.2% of transmission problems, with high maintenance complexity and cost. However, if the special transmission fluid is replaced regularly and aggressive driving is avoided, automatic transmissions (such as AT, CVT or dual-clutch) can also achieve a long service life. Manual transmissions are suitable for drivers who pursue economy and a sense of control, while automatic transmissions are more suitable for urban commuting. When choosing, personal needs should be considered, and good maintenance is the key to extending the transmission's service life.
