How often should the Corolla transmission fluid be changed?

[VanEzra]

Transmission fluid usually needs to be changed every two years or 60,000 kilometers to transmit power, lubricate for smooth operation, and dissipate heat. The relevant introduction to transmission fluid replacement is as follows: Transmission fluid replacement interval: Whether it's a manual or automatic transmission, the fluid should be changed every two years or 60,000 kilometers. Especially for automatic transmissions, maintenance is crucial, and the transmission fluid should be replaced every 60,000 kilometers. Transmission fluid replacement methods: 1. Gravity Drain: The fluid is drained using gravity, with a replacement rate of about 40%. The principle is the same as changing engine oil. For example, an 8-liter transmission can have 3 to 4 liters replaced. 2. Machine-Assisted Replacement: A machine generates pressure to dynamically replace the fluid in the torque converter's lubrication and cooling lines, achieving a replacement rate of over 80%. This method is simple and thorough but requires specific equipment and skilled technical support.
