How to Use Transmission Fluid Correctly?

[PaulDella]

Transmission fluid primarily functions to maintain the cleanliness of the gear system and provides lubrication and longevity to the transmission components. The correct methods for using transmission fluid are as follows: 1. Generally, the automatic transmission fluid (ATF) in a car should be replaced every two years or every 40,000 kilometers. However, this varies depending on the vehicle model. For Japanese models, it is recommended to replace the fluid every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the fluid approximately every 40,000 kilometers. 2. If the oil pan is removed for fluid replacement, up to 70% of the fluid can be replaced to ensure the transmission's health. Currently, the preferred method is dynamic fluid replacement, which uses specialized transmission cleaning equipment to fully circulate and drain the old fluid before adding new fluid, achieving a replacement rate of over 90%.
