What are the types of transmission fluid?
2 Answers
Currently, the main types of transmission fluid used in China are DEXRON, DEXRON-Ⅱ, and DEXRON-Ⅲ. More details about transmissions are as follows: 1. The transmission, also known as the gearbox, is an automotive component used to alter the speed and torque from the engine, and can fix or change the gear ratio between the output shaft and input shaft. 2. The transmission consists of a gear shifting mechanism and an operating mechanism, with some vehicles also including a power take-off mechanism. It can be categorized into stepped, continuously variable, and integrated transmissions, and functions include enabling reverse driving, interrupting power transmission, and changing gear ratios.
There are various types of transmission fluid, and the key is to consider the transmission type. I often perform DIY car maintenance, and for manual transmissions, GL series fluids are commonly used. GL-4 is suitable for regular manual transmissions, while GL-5 offers stronger anti-corrosion properties and is ideal for high-performance models. Automatic transmission fluid (ATF) is more complex, with older types like DEXRON III and newer, more energy-efficient options like DEXRON VI. CVT transmissions require specialized fluid, with Nissan's NS-2 or NS-3 being common choices. DCT dual-clutch transmissions, such as those in Volkswagen models, also require specific fluids. Using the wrong type can lead to rough shifting or transmission wear. I once made the mistake of using the wrong fluid and nearly caused damage, so I recommend checking the vehicle manual or consulting a professional. The fluid change interval is typically every 40,000 to 60,000 kilometers. When doing it yourself, ensure the fluid level is correct and avoid cheap, low-quality products. Using the right fluid long-term protects the drivetrain and saves on major repair costs.
