Is it necessary to change the transmission fluid for an automatic transmission?
2 Answers
It is necessary to change the transmission fluid for an automatic transmission regularly. If the transmission fluid is not changed for a long time, it will accelerate the wear of the transmission and may also cause damage to the gear shift control mechanism. When changing the transmission fluid, it is recommended to use the circulating machine method, which can remove more than 90% of the old transmission fluid. It is essential to choose the original manufacturer's fluid when changing the transmission fluid, as it has been tested by the manufacturer to ensure it meets the transmission's requirements under all operating conditions. There are three common types of automatic transmissions in cars: dual-clutch transmission (DCT), automatic transmission (AT), and continuously variable transmission (CVT).
Yes, automatic transmission fluid absolutely needs to be changed—it's as crucial as giving your car a blood transfusion. I've seen too many cases where old fluid leads to increased gear wear, clunky shifts, and diminished lubrication and cooling once the additives break down, resulting in overheating or even transmission failure. Over time, fuel efficiency drops, acceleration weakens, and you might experience sudden jerks when climbing hills. Follow your owner's manual—typically every 40,000 km or 3 years—and don’t delay. Have a professional check the fluid color; fresh fluid is red, but if it turns black, replace it immediately. Neglecting this could cost thousands in repairs, far more than a fluid change. Stick with reputable brands—cheap alternatives aren’t worth the risk. Regular maintenance keeps your car running smoothly, saving both hassle and money.
