How to Change the Oil in an Automatic Transmission Machine?
2 Answers
Steps for changing the oil in an automatic transmission machine: 1. First, add the transmission FLUSH cleaner into the transmission to allow the cleaner to break down the oil film on the gears as much as possible; 2. Lift the car, switch between D and R gears, and run for 5 to 10 minutes. These two steps will clean the automatic transmission; 3. Drain the old oil. Although the automatic transmission undergoes one oil change, long-term use makes it impossible to clean the transmission thoroughly in just one cycle. This cleaning process needs to be repeated twice; 4. Add 2 to 3 liters of new transmission oil, repeat the second step to circulate again, and remove as much sludge as possible from the gears before draining the oil; 5. Remove the transmission pan; 6. Add new oil by pouring the prepared automatic transmission oil into the system to complete the process.
I used to change the automatic transmission fluid in my own garage. It's a meticulous job, but doing it yourself can save a lot of money. The whole process requires ensuring safety—the engine must be completely cooled down, and gloves should be worn to prevent burns. The tools needed are simple: an oil drain pan, a wrench, a funnel, and the correct type of new transmission fluid that matches your car—never use the wrong type. The first step is to locate the drain plug at the bottom of the transmission, unscrew it to drain the old fluid into the pan, and patiently wait a few minutes for it to fully drain. Don’t forget to check the filter—some cars have one, and it should be replaced with a new one to prevent dirty fluid from contaminating the new oil. Then, tighten the drain plug and slowly pour in the new fluid through the fill hole using a funnel until the dipstick shows the full mark. After finishing, start the engine, drive a few kilometers to test the gear shifts, then turn it off and recheck the fluid level, topping up if necessary. Doing it yourself takes less than half an hour and saves at least a few hundred dollars in costs. But if you're not familiar with it, I recommend first learning the procedure from a repair shop mechanic—using the wrong fluid type can damage the transmission.
