What is the purpose of changing transmission fluid?
1 Answers
Changing transmission fluid serves to maintain the cleanliness of the gear shifting system and provides lubrication to the transmission components, thereby extending their service life. Due to differences in transmission design, there are manual transmissions and automatic transmissions, each with its own specific technical requirements. Even for the same model of transmission installed in different vehicle models, the manufacturer specifies its own dedicated transmission fluid. Transmission fluid performs functions such as cleaning, lubrication, heat dissipation, and sealing for the transmission. Given the specific operating environment inside the transmission, the quality of the fluid has a limited lifespan. Over time, the performance of the fluid deteriorates, leading to increased impurities, which in turn accelerates the wear of transmission components, causing premature failures or higher failure rates.
