How Often Should You Change Transmission Fluid?
2 Answers
It is recommended to change it every 40,000 kilometers or so. Here is some relevant information about transmission fluid: 1. Transmission fluid is an oil product that keeps the gear system clean, lubricates to extend the service life of transmission components, and provides effective lubrication even at low temperatures. It reduces oil loss under harsh operating conditions. Depending on the transmission structure, transmission fluid is divided into automatic transmission fluid and manual transmission fluid. 2. Most transmission fluids can be used in automatic transmissions on the market. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have differences in torque, weight, speed, and structure. Therefore, the original manufacturer has its own specified dedicated transmission fluid. Different transmission fluids are one of the factors affecting shift quality.
To be honest, I've driven quite a few cars, and the frequency of transmission fluid changes really can't be generalized. I remember when I was younger and forgot to change it once, my manual transmission car started making clunking noises after just 60,000 kilometers, costing me a lot in unnecessary repair fees. Now I always refer to the owner's manual - most automatic transmissions recommend changing every 40,000 to 60,000 kilometers or every 3-4 years; manual transmissions can last up to about 70,000 kilometers. But road conditions make a big difference - if you're frequently starting and stopping in city traffic, causing rapid oil temperature rises, it's best to get it checked as early as 30,000 kilometers. Vehicle differences matter too, with CVT or DSG transmissions having stricter requirements. Always have professional technicians handle the fluid change process - don't try to save on this small expense, because a ruined transmission will cost you dearly.
