How Many Liters of Transmission Fluid Are Needed for a Corolla Transmission Fluid Change?

[LaElena]

For a Corolla transmission fluid change, using the manual fluid change method (gravity drain), approximately 4 to 6 liters are required; if using a fluid exchange machine, around 9 to 12 liters are needed. The Corolla is equipped with a CVT (Continuously Variable Transmission), while the Corolla Hybrid features an E-CVT (Electronic Continuously Variable Transmission) system, which is a transmission specially developed and tuned by Toyota for hybrid models. Hazards of Not Changing Transmission Fluid: Damage to the transmission's shift control mechanism; abnormal wear of gears and clutch plates inside the transmission; impaired transmission operation, leading to damage of the transmission valve body. Types of Transmission Fluid: Transmission fluid is generally categorized into three types: manual transmission fluid, automatic transmission fluid, and continuously variable transmission fluid. Manual transmission fluid is commonly referred to as gear oil. Automatic transmission fluid is commonly known as ATF (Automatic Transmission Fluid). Continuously variable transmission fluid is commonly called CVTF (Continuously Variable Transmission Fluid).
