How many kilometers should I change the transmission oil for my car?
Changing gearbox oil seems simple, but if you don't pay attention and change it at the right time, it will cause unexpected damage to your car's engine.
According to experts, automatic transmissions equipped in cars include two types: Automatic transmissions with oil dipsticks (open transmissions) and automatic transmissions without oil dipsticks (closed transmissions).
Car manufacturers recommend changing the automatic transmission oil for cars every 50,000km for cars with open gearboxes. For closed gearboxes, experienced users recommend changing it after about 120,000 - 150,000km.

Automatic transmissions use a separate transmission fluid called ATF (Automatic Transmission Fluid) which plays a role in transmitting engine power, lubricating gears, bearings, etc.
Therefore, gearbox oil has some very strict requirements such as anti-foaming properties, maintaining fluidity at low temperatures, viscosity index with little change... Therefore, when changing, you must choose the right type of oil.
In addition, each manufacturer has different requirements for transmission fluid change schedules. Therefore, first find out the information in the owner's manual that comes with the car.
Technically, draining automatic transmission fluid is more complicated than engine oil, so it is necessary to drain all the oil from the bottom of the crankcase and in the torque converter.
Before draining the oil, you need to warm up the engine, then remove the automatic transmission oil drain bolt at the bottom of the crankcase to drain all the oil, then continue draining the oil in the torque converter. During the oil drain, you need to start the car and put it in gear so that the amount of oil in the torque converter is pushed out./.
