How often should the automatic transmission fluid be changed in a Langdong?
2 Answers
According to the official instructions for the Langdong, the manual transmission fluid should be changed every 70,000 kilometers. Under normal circumstances, the automatic transmission fluid does not need to be changed. Relevant details are as follows: 1. Most transmission fluids on the market are suitable for automatic transmissions. In fact, each automatic transmission design has different technical requirements. Even the same model of transmission configured in different vehicles may have differences in torque, weight, speed, structure, etc. Therefore, the original manufacturer specifies its own designated transmission fluid. 2. A manual transmission consists of gear sets with different gear ratios. Its basic working principle is to switch between different gear sets to achieve gear ratio changes. As a key component in power distribution, the transmission must have two major parts: a power input shaft and an output shaft, along with the gears that make up the transmission, forming the most basic components of a manual transmission.
I've been driving a Nissan Sunny with an automatic transmission for several years, and I feel the transmission fluid change interval is quite important. Generally, manufacturers recommend changing it every 40,000 to 60,000 kilometers, or every 2 to 3 years, depending on the owner's manual. My experience is that regular maintenance prevents small issues from becoming big problems. If you frequently drive on highways or encounter heavy city traffic, the fluid tends to degrade faster, so I change it at 40,000 kilometers. Remember to check the fluid level and color—if it turns black or smells burnt, it's definitely time for a change. Neglecting to change the fluid can lead to overheating, increased wear, and ultimately expensive repairs, possibly even requiring a full transmission replacement. I recommend everyone develop this habit to save money and have peace of mind. If you're not familiar with the process, take it to a dealership or professional shop—don't cut corners and risk bigger issues.
