What are the steps for changing automatic transmission fluid?
2 Answers
Automatic transmission fluid change steps are: 1. Lift the vehicle, place a large container under the car to catch the used fluid, and use an appropriate screwdriver to remove the transmission inner and outer covers; 2. When most fluid has drained, remove the last oil pan and carefully support it by hand as it still contains a significant amount of fluid; 3. Carefully remove the transmission fluid filter, at which point the solenoid valves controlling gear shifts become clearly visible; 4. Remove the oil pan gasket and clean surrounding residue - tools may be used if gaps aren't thoroughly cleaned; 5. Wipe all cleaned transmission filter components with cotton yarn before reinstalling them one by one; 6. Wipe surfaces of replaced parts dry (avoiding water or oil stains that may cause leaks), install cleaned oil pan and gasket with proper sealing, clean and wipe the filter housing, reinstall cleaned housing, and add manufacturer-recommended fluid.
I just changed the automatic transmission fluid in my car, and it wasn't too difficult but required attention to detail. First, I had to prepare new fluid, an oil drain pan, wrenches, and other tools. The amount of fluid varies by car model, and I checked the manual to confirm that 5 liters were needed. After parking and turning off the engine, I waited for it to cool down to avoid burns. Then, I crawled under the car to locate the transmission pan, loosened the drain plug to let the old fluid out—it was dark and dirty, a clear sign it needed changing. I also replaced the filter and sealing gasket to prevent leaks. When adding new fluid, I used a funnel to pour it in slowly. After filling, I started the engine and shifted gears to circulate the fluid, then checked the dipstick and topped it off to the correct level. After the change, the car drove noticeably smoother. I recommend doing this every 60,000 kilometers to extend its lifespan.
