Here are the methods for changing automatic transmission fluid: 1. Gravity drain, which uses gravity to replace the fluid. 2. Using a circulation machine to change the transmission fluid, which provides a more thorough and clean replacement. Here are the benefits of regularly changing automatic transmission fluid: 1. It can make gear shifting smooth and improve handling performance. 2. It provides good oxidation resistance, reducing rust on mechanical parts. 3. Excellent extreme pressure additives offer optimal protection for gear sets. 4. The replacement cycle for automatic transmission fluid is based on mileage or usage time.
I've been driving for over 30 years, and the methods for changing automatic transmission fluid have changed significantly. Back when I drove older cars, the process was straightforward: find a level spot, jack up the car, crawl underneath to locate the drain plug, unscrew it to drain the old fluid, then tighten it and add new fluid. You could do it yourself in half an hour—saving money and hassle. But modern car designs are more complex; the oil pan might be sealed or integrated with the filter, requiring specialized tools for removal. If you're not experienced, it's easy to damage parts. You also need to use the correct fluid type—no mixing with low-quality oils—or the transmission will wear out quickly, leading to sky-high repair costs. I recommend changing the fluid every 40,000 kilometers to prevent issues and extend its lifespan. It's best to get it serviced at a reputable shop rather than trying to DIY.
