Why does the car feel more powerful after changing the transmission fluid?
2 Answers
Transmission fluid serves multiple functions including cleaning, lubrication, rust prevention, and heat dissipation. Regularly changing the transmission fluid can clean and lubricate the gear system, extend the lifespan of the transmission components, ensure the transmission operates normally, and make gear shifts smoother and more seamless, potentially restoring the feeling of driving a new car. More details about transmission fluid are as follows: 1. Regular replacement: If the transmission fluid is not changed for a long time, it can affect the vehicle's operation. The performance of the transmission fluid will degrade, reducing its lubrication effectiveness, which accelerates the wear of transmission components and increases the likelihood of malfunctions. 2. Transmission fluid is a consumable item: Transmission fluid operates under high-speed and high-temperature conditions for extended periods, leading to deterioration and evaporation. This can exacerbate the wear of mechanical parts and, in severe cases, damage internal transmission components.
I was quite surprised that the power noticeably improved after I changed the transmission fluid last week. Before the fluid change, the car always felt sluggish with delayed acceleration, probably because the old fluid had been used for too long and became dirty and degraded. The impurities and sludge in it increased the internal friction resistance of the transmission, leading to lower transmission efficiency. With the new fluid in place, the lubrication effect is better, metal components slide more smoothly, energy loss is reduced, and the power is naturally transmitted more directly to the wheels. Additionally, it might be psychological—right after maintenance, the car always feels brand new—but scientifically, fluid cleanliness does indeed affect power output. I recommend regular maintenance; don’t wait until major issues arise. Like me, changing it every two years or after 50,000 kilometers can prevent transmission wear and extend its lifespan. By the way, checking the fluid color is simple—if it’s deep black, don’t delay, change it right away to avoid costly repairs later.
