Is It Necessary to Change Transmission Fluid?
1 Answers
Transmission fluid must be changed. Below are specific details about transmission fluid: 1. Reasons: Due to the special road conditions where vehicles operate, such as traffic congestion and poor air quality, transmission fluid is prone to oxidation, deterioration, and reduced viscosity. This increases wear between friction plates, raises fuel consumption, and affects performance. Automatic Transmission Fluid (ATF) serves two main functions: transmitting hydraulic power and providing cleaning lubrication. If transmission fluid is not changed for a long time, it can lead to larger particle sizes or the generation of debris, which may block oil passages, damage the valve body, clog pistons, and even cause gear shifting impacts. Therefore, transmission fluid must be changed regularly. 2. Interval: The transmission is a highly precise assembly with a complex structure. It is recommended to change the transmission fluid every 40,000 kilometers. In areas with good usage conditions, it can be changed every 80,000 kilometers (or 48 months). However, in mainland China, it is advised to change the transmission fluid every 40,000 kilometers (or 24 months). Sometimes, depending on usage, it may be recommended to change the transmission fluid every 20,000 kilometers (or 12 months).
