Is Changing Transmission Fluid Beneficial?
2 Answers
Changing transmission fluid is beneficial. The details are as follows: 1. Benefits of changing transmission fluid: (1) Transmission fluid has functions such as cleaning, lubrication, rust prevention, and heat dissipation. Regularly changing the transmission fluid can clean and lubricate the gearshift system, extend the lifespan of the transmission components, ensure the normal operation of the transmission, and make gear shifts smoother and more effortless, possibly restoring the feeling of a new car. (2) From another perspective, changing transmission fluid can also reduce fuel consumption, meaning that after changing the transmission fluid, the car may become more fuel-efficient. Of course, it is important to use high-quality transmission fluid and avoid counterfeit or inferior products. It is best to use the specific type recommended for your vehicle and follow the manufacturer's guidelines for replacement. 2. Consequences of not changing transmission fluid: (1) If the transmission fluid is not changed for a long time, it will not only affect the operation but also degrade the performance of the transmission fluid, reducing its lubrication effect. This can lead to accelerated wear of transmission components and an increased likelihood of malfunctions. (2) Over time, the transmission fluid will accumulate impurities, making the transmission dirty. This can result in higher shift RPMs and increased fuel consumption.
This stuff is actually pretty important. My old car hadn't had its transmission fluid changed for 100,000 kilometers, and shifting became increasingly stiff. When the mechanic opened it up, the fluid had turned into sludge. Fresh fluid not only lubricates the gears to reduce wear but also helps cool the transmission, especially during stop-and-go traffic when temperatures spike. That jerky feeling during gear shifts? Mostly caused by too much metal debris and contaminants in the old fluid. Recommendation: change it every 60,000-80,000 km. Use a flush machine for a more thorough replacement—don't cheap out on this. A transmission repair could cost you dozens of fluid changes. For cars with metal oil pans, make sure the mechanic replaces the filter screen too.
