What is Transmission Fluid?
2 Answers
Transmission fluid is a type of gear oil used in the transmission system to keep the gear shifting system clean. It serves to lubricate and extend the lifespan of the transmission components, providing effective lubrication even at low temperatures. Under harsh operating conditions, it helps reduce oil loss. Most transmission fluids are compatible with automatic transmissions available on the market. However, each automatic transmission design has unique technical requirements. Even the same model of transmission configured in different vehicle models may vary in torque, weight, speed, and structure. Therefore, manufacturers specify their own dedicated transmission fluids. Different transmission fluids can significantly impact the quality of gear shifting.
Transmission fluid is like a special liquid added to a car's transmission system, primarily serving to lubricate the gears and bearings inside, ensuring smooth rotation and preventing overheating damage caused by friction. It also aids in heat dissipation, especially during high-speed driving or traffic congestion, as excessive oil temperature can easily lead to transmission issues. Automatic transmission fluid has an additional critical function—transmitting hydraulic power to facilitate smoother gear shifts. I've encountered many vehicles where deteriorated fluid, such as turning black or emitting a burnt smell, resulted in strange noises or even transmission failure. It's recommended to inspect the fluid every 40,000 to 60,000 kilometers and replace it according to the vehicle's manual guidelines. Using reputable brand products can significantly extend the transmission's lifespan.
