How Many Kilometers to Change Transmission Oil?
2 Answers
Transmission oil should be changed every two years or 40,000 kilometers. Below is relevant information: 1. The frequency of changing transmission oil varies for different vehicle models. For manual transmission cars, the transmission oil is only used for lubrication, and the gear precision requirements in manual transmission systems are not very high. Therefore, slightly inferior transmission oil has minimal impact. 2. Automatic transmission cars have more complex systems with higher operational requirements. Here, transmission oil serves more purposes than in manual transmission cars. If the transmission oil becomes dirty or accumulates impurities, it can accelerate transmission wear and reduce shifting speed.
I've driven several cars and found the mileage for changing transmission fluid crucial. Generally speaking, changing it every 40,000 km or so is a good idea - that's my personal experience. My first car was a manual transmission, and I didn't think about changing the fluid until 60,000 km, which resulted in grinding noises from the transmission and cost me thousands in repairs. Since then, I've always stuck to timely changes. For automatic transmissions, if you frequently drive on highways or tow heavy loads, you might need to change it every 30,000 km to prevent sludge buildup that could cause gear sticking. If you notice rough shifting or hesitation during gear changes while driving, those are signs of fluid degradation. Remember, delaying fluid changes accelerates wear - transmission repairs can become endless. I recommend checking your vehicle's manual as requirements vary by brand. Developing regular maintenance habits ensures your car stays with you for the long haul.
