Do manual transmission cars need to change the gearbox oil?
2 Answers
Manual transmission cars do need to change the gearbox oil. The replacement interval for manual transmission fluid is relatively long, typically every 2-4 years or 60,000 kilometers. If the vehicle is not used intensively, it can be changed every 100,000 kilometers. For high-intensity usage, replacement is recommended every 60,000-80,000 kilometers. Transmission oil operating under prolonged high temperatures can deteriorate or evaporate, accelerating wear on mechanical components, and in severe cases, may damage internal transmission parts. The hazards of not changing transmission oil include: 1. After prolonged non-replacement, the vehicle may experience weak acceleration when starting cold. 2. Over time, the transmission oil becomes thicker, potentially obstructing the transmission cooler, leading to excessively high oil temperatures and increased wear.
As a technician who frequently works with various car models, I've seen many manual transmission owners neglect gear oil changes. Manual transmission fluid does require regular replacement, typically recommended every 60,000-100,000 kilometers. Its primary function is to lubricate gears and bearings, reducing friction and wear between metal components. If left unchanged for extended periods, the fluid deteriorates and loses effectiveness, leading to rough shifting and even gearbox noises. Last time, a Lavida owner drove 150,000 kilometers without an oil change, resulting in severe synchronizer wear - the repair cost was ten times more expensive than an oil change. While manual transmissions are more durable than automatics, regular maintenance is crucial for longevity. I recommend adjusting the interval based on driving habits, such as advancing the change schedule for frequent stop-and-go traffic or aggressive driving.
