How to Add Transmission Fluid for Toyota Corolla?
1 Answers
When adding transmission fluid to a new Corolla, open the engine compartment, then remove the transmission dipstick and use a funnel to directly pour in the fluid. For the new Corolla, whether to change the transmission fluid can be determined based on the operating condition of the vehicle's transmission. If gear shifting feels rough, especially when the speed exceeds 100 km/h and the transmission noise becomes noticeably louder, it may be time to consider changing the transmission fluid. More details about transmission fluid are as follows: 1. Transmission fluid is a lubricant that keeps the transmission system clean, ensuring normal operation and extending the lifespan of the transmission components. Depending on the transmission type, transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid, typically red in color. 2. Over time, the viscosity of transmission fluid thins, leading to reduced lubrication, decreased sealing performance, increased resistance, and accelerated wear. This results in unstable pressure and affects the precision of the hydraulic system. The control and shifting precision of the transmission deteriorate, impacting smoothness and response speed. Deteriorated fluid also loses its cooling and anti-oxidation properties, making it prone to overheating issues, creating a vicious cycle that further shortens the lifespan of the fluid and transmission components. 3. Currently, there are three mainstream methods for changing automatic transmission fluid: The first method is similar to an oil change, where the transmission drain plug is loosened to drain and refill the fluid. The second involves removing the oil pan for draining and refilling. The third and more advanced method uses a circulation machine to replace the automatic transmission fluid.
