How Many Kilometers to Change Transmission Oil?
2 Answers
Automatic transmission oil should be changed approximately every two years or after driving 50,000-80,000 kilometers; manual transmission oil is generally changed every three years or around 100,000 kilometers. Below are detailed explanations: 1. Transmission oil is used in automobile transmissions to clean and lubricate the gear system, extend the lifespan of transmission components, and serves functions such as cleaning, lubrication, rust prevention, and heat dissipation. Depending on the type of vehicle transmission, transmission oil can be categorized into manual transmission oil and automatic transmission oil. 2. Vehicle owners can determine whether to change the transmission oil based on the operating condition of the transmission. If the vehicle's gear shifting feels less smooth, especially when the transmission noise becomes noticeably louder at speeds exceeding 100 kilometers per hour, it may be time to consider changing the transmission oil. 3. When selecting and changing transmission oil, it is crucial to strictly follow the manufacturer's recommendations, ideally using oil specifically designed for the vehicle model, and avoid counterfeit or substandard transmission oil.
I've been driving an old manual transmission car for many years, and the gearbox oil change isn't as strict, but it's best to check it every 30,000 to 50,000 kilometers. My Toyota Corolla manual recommends changing it every 50,000 kilometers, but I tried doing it at 40,000 because I drive more on mountain roads, and the gear wear is greater. If shifting feels rough or you notice any hesitation, that's a sign it's time to change. Don't wait too long, or carbon buildup in the transmission can double the repair costs. I often carry an oil gauge to check the fluid—if it's black or too thick, it's time for a change. You can even do it yourself when changing the oil; choosing the right type is crucial. Regular mineral oil is cheaper than full synthetic, but it's sufficient if you don't drive on highways. Remember, don't skimp on cheap, low-quality oil—it can ruin your car and make things worse. In short, it depends on the car's condition and driving habits—change more often in city traffic, but you can stretch the mileage in suburban or highway driving.
