How often should the transmission fluid be changed by machine?
2 Answers
For automatic transmission fluid in vehicles, it is generally recommended to replace it every 40,000 kilometers or so. Here is some information about automatic transmissions: 1. Vehicle owners can determine whether to change the transmission fluid based on the operating condition of the transmission. If gear shifting is smooth and there is no significant change in transmission noise, replacement may not be necessary. However, if gear shifting becomes rough, especially when the vehicle speed exceeds 100 km/h and the transmission noise increases noticeably, it may be time to consider changing the transmission fluid. 2. The automatic transmission is a crucial component of the vehicle's drivetrain and one of the most precise parts. Over time, the viscosity of the transmission fluid will thin, leading to reduced lubrication and sealing performance, increased resistance and wear, unstable pressure, and compromised precision in the hydraulic system. This can result in decreased transmission control accuracy, poorer shift precision, and reduced smoothness and responsiveness.
Last time I went for maintenance, I specifically asked the technician about the machine transmission fluid change process, which is actually quite particular. Automatic transmission cars usually take about half an hour to an hour, while manual transmissions can be done faster. However, it depends on the condition of the circulation machine - newer workshop equipment is more efficient. The technician recommended changing it every 60,000-80,000 kilometers, especially for drivers who frequently floor the accelerator. For vehicles over ten years old or those often driven on mountain roads or dirt paths, it's better to have it checked at 50,000 kilometers. Remember to use the manufacturer-specified fluid - don't try to save a few bucks with off-brand products, as transmission repairs cost much more than fluid changes. Temperature also affects the process - in winter, it takes about ten extra minutes to preheat the fluid.
