How Often Should CVT Transmission Fluid Be Changed?
1 Answers
CVT transmission fluid generally needs to be changed every two years or every 40,000 kilometers. However, this may vary depending on the vehicle model, as different models have different requirements. The primary function of transmission fluid is to keep the shifting system clean and to lubricate the transmission components, thereby extending their lifespan. Below is more detailed information: 1. Due to differences in transmission design, transmissions are categorized into manual and automatic (which further includes CVT, AMT, etc.). Each transmission type has unique technical requirements. Even the same transmission model, when installed in different vehicles, may differ in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluids. 2. Automatic transmission fluid (ATF) is specifically designed for automatic transmissions. Early automatic transmissions did not use dedicated fluid but instead relied on engine oil. Due to significant differences in operating conditions and technical requirements, using engine oil as transmission fluid was quickly phased out. Modern automatic transmission fluid serves as both the hydraulic fluid for the torque converter and the lubricant for the planetary gear structure, as well as the hydraulic fluid for the shifting mechanism. Under normal driving conditions, ATF should be changed every 120,000 kilometers, while under severe driving conditions, it should be changed every 60,000 kilometers.
