How many kilometers should an automatic transmission's oil be changed?
2 Answers
Under normal circumstances, the transmission fluid in an automatic transmission should be changed every 60,000 to 80,000 kilometers. Failure to change the transmission fluid for an extended period can lead to automatic transmission malfunctions. Here are some relevant details: 1. The transmission fluid in an automatic transmission not only serves the purposes of lubrication and heat dissipation but also functions to transmit force. 2. Inside the automatic transmission, there are gear shift control mechanisms that rely on the transmission fluid to operate correctly. Prolonged failure to change the transmission fluid can result in excessive impurities in the fluid, potentially damaging the transmission's gear shift control mechanisms. If these mechanisms are damaged, the repair costs can be quite high.
I've been driving automatic transmission cars for many years. Generally, it's recommended to change the transmission fluid every 50,000 kilometers, but it really depends on your driving habits and the vehicle's manual. For example, since I mostly commute in the city without aggressive driving, I can stretch it to around 60,000 kilometers before changing. However, if you frequently drive on highways or tow heavy loads, the fluid deteriorates faster, and you might need to change it as early as 40,000 kilometers. I remember once when I didn't change it on time, the transmission started making strange noises, and the repair cost me thousands. Regular fluid changes protect the internal gears and extend the transmission's lifespan. Keep an eye on the fluid's color; if it turns black or has a burnt smell, it's time for a check-up. Overall, just follow the manufacturer's guidelines—don't try to save a little money now, or you'll regret it when facing major repairs later.
