What are the symptoms after changing transmission fluid?

[DelAngela]

After changing the transmission fluid, the vehicle may experience symptoms such as difficulty shifting gears and gear grinding. The methods for maintaining a vehicle's transmission are as follows: 1. Choose transmission fluid with appropriate viscosity: If the viscosity is too high, it can cause excessive heat on friction surfaces, leading to unnecessary power loss. Conversely, if the viscosity is too low, centrifugal force may cause the fluid to be thrown off gear surfaces, resulting in oil seal leakage. This could lead to insufficient lubrication on gear surfaces, increasing wear and potentially causing sintering. Therefore, selecting the right viscosity is crucial. Refer to the vehicle's owner's manual or service manual when changing the fluid. 2. Use high-quality branded transmission fluid: High-quality branded transmission fluid effectively protects gears, reduces wear, makes vehicle operation smoother, improves fuel efficiency, extends fluid service life, and lowers maintenance costs. When selecting transmission fluid, avoid choosing cheap options. Always purchase high-quality branded transmission fluid from authorized sales channels. This not only protects your vehicle but also reduces maintenance costs in the long run.
