What is the purpose of changing transmission fluid?
2 Answers
The purpose of changing transmission fluid is to maintain the cleanliness of the gear system and provide lubrication to the transmission components, thereby extending their lifespan. Signs that indicate the need for a transmission fluid change include: 1. Vehicle shaking and gear shifting hesitation; 2. Transmission overheating warning on the dashboard; 3. Engine stalling; 4. Unusual noises. Methods for changing transmission fluid are: 1. Loosen the tightening nut at the bottom of the oil pan, allowing the transmission fluid to automatically drain from the oil drain hole; 2. Connect the transmission to a circulation machine via pipeline interfaces to push out the old fluid with new fluid; 3. Remove the oil pan for fluid replacement. The functions of the transmission are: 1. Altering the transmission ratio; 2. Expanding the torque and speed of the drive wheels; 3. Enabling the vehicle to reverse; 4. Facilitating gear shifting or power output in the transmission.
Since I started driving my own car, the importance of transmission fluid cannot be underestimated. It lubricates the gears, shafts, and clutch plates inside, reducing wear and preventing metal parts from overheating and seizing due to friction. The fluid also helps dissipate heat, absorbing the heat transferred from the engine to the transmission to avoid internal burning or deformation. Additionally, during fluid changes, it carries away metal shavings and debris, ensuring the oil passages remain clear and unclogged. Last time I forgot to change the fluid, the car's gear shifts became jerky and terrifying, costing me thousands in repairs to replace parts. So, changing the fluid every 40,000 to 50,000 kilometers keeps the car running smoothly, saves hassle, and can extend the transmission's lifespan by over a decade. Don't skimp on this small expense—proper maintenance prevents major headaches.
