The transmission oil for automatic shift needs to be changed every 4-8万公里 or every 2-4 years; while the manual shift needs to be changed every 4 to 6万公里. Transmission oil is a crucial component of a car's transmission system, playing an essential role in maintaining the cleanliness of the system and providing lubrication and extending the life of the transmission. The automatic and manual shift have different technical requirements, and the life of the transmission oil is also different accordingly.

Transmission oil is essential for maintaining the transmission system's cleanliness and providing lubrication and extending the life of the transmission. The transmission is a closely related component, and if the transmission oil is used for too long, its viscosity will decrease, leading to a decrease in its lubricating performance, a decrease in its sealing performance, and an increase in wear due to the rise in resistance, resulting in an unstable pressure and a decrease in the transmission's adjustment accuracy and shift accuracy.

The transmission oil for manual shift needs to be changed every 4 to 6万公里. The life of the transmission oil is crucial for maintaining the transmission system's cleanliness and providing lubrication and extending the life of the transmission. The automatic and manual shift have different technical requirements, and the life of the transmission oil is also different accordingly.
