What are the methods for changing automatic transmission fluid?
3 Answers
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.
As a car enthusiast, I often change the automatic transmission fluid myself. The basic steps are: first warm up the car for a few minutes to ensure the fluid flows smoothly, locate the drain plug on the undercarriage and unscrew it to drain all the old fluid. Most models have a filter in the oil pan, so remove it to clean or replace it with a new one to ensure cleanliness. Then, when adding new fluid, use a funnel to pour it in slowly. After starting the car, check if the fluid level is within the marked range on the dipstick. Some modern cars require a flushing machine to thoroughly clean the lines and replace the fluid more completely, but for DIY, gravity draining is sufficient. Remember to choose the manufacturer-specified specialized fluid—don't skimp and buy random products, or the transmission may jerk and fail. Regular changes protect internal components, saving money and ensuring safety.
