What Are the Disadvantages of Not Changing Transmission Fluid?
1 Answers
The following are the disadvantages of not changing transmission fluid: 1. Reduced lubrication. Transmission fluid continuously breaks down with use and time. If not replaced, its viscosity and lubricating properties will gradually decline and it may adhere to critical components. Friction caused by contaminated fluid can lead to floating metal particles continuously scratching bearings, races, gears, and other parts, potentially resulting in transmission shuddering, failure to shift, misalignment, or even gear and bearing breakage. 2. Overheating of the transmission. In addition to lubrication, transmission fluid also cools the transmission. Prolonged failure to replace old fluid can cause the transmission to overheat continuously. This heat further weakens the viscosity and lubricating properties of the transmission fluid, creating additional friction. O-rings, gaskets, rubber seals, and other sealing components in automatic transmissions may also deform or melt due to overheating. 3. Potential internal blockage of the transmission. Various deposits can form inside the transmission, and when combined with metal particles, they can clog the transmission, check valves, and filters, leading to abnormal internal pressure. Automatic transmissions rely on precise pressure to operate, and abnormal pressure can cause sealing failures. In manual transmissions, blockages may result in shifting failure or gear misalignment.
