What are the consequences of not changing automatic transmission fluid?
1 Answers
Failure to replace automatic transmission fluid will result in poor lubrication and affect vehicle performance. Transmission fluid gradually degrades over time. Without replacement, its viscosity and lubricating properties deteriorate, leading to accumulation on critical components. Contaminated fluid causes metal particles suspended in the oil to continuously abrade bearings, races, gears and other parts, potentially resulting in transmission vibration, gear shifting failure, displacement issues, or even gear and bearing fractures. The transmission is a vital automotive component that alters gear ratios and amplifies driving wheel torque and speed. Transmission fluid primarily maintains gear system cleanliness while lubricating and prolonging the service life of transmission components. Generally, transmission fluid serves three key functions: 1) Heat dissipation - gear interactions generate substantial heat requiring lubrication for cooling; 2) Lubrication - ensuring smoother gear engagement; 3) Cleaning - maintaining gear system cleanliness to extend transmission component lifespan.
