A car's transmission often breaks down due to the degradation of its fluid, leading to damaging friction and the eventual failure of internal components.
The transmission is a complex system of gears and other parts that work together to transfer power from the engine to the wheels. For these parts to function smoothly and prevent damage, they require proper lubrication, which is provided by transmission fluid.
Over time and with accumulated mileage, this crucial fluid loses its effectiveness.
The Chain Reaction Leading to Transmission Failure
Based on expert insights, a primary cause of transmission breakdown is linked directly to the state of the transmission fluid:
- Fluid Degradation: Transmission fluid naturally diminishes in its lubricating abilities over time and as mileage increases.
- Increased Friction: When the fluid can no longer lubricate effectively, it allows damaging friction to occur between the transmission's internal parts.
- Part Breakdown and Debris: This excessive friction causes the parts within the transmission to break down.
- Buildup of Sludge: The breakdown of parts, combined with the degraded fluid, leads to a buildup of debris and often a thick, harmful sludge within the system.
- Complete Failure: All these accumulated issues—diminished lubrication, friction, damaged parts, debris, and sludge—work together, eventually leading to a complete transmission breakdown.
Essentially, the lack of proper lubrication starts a domino effect where friction destroys components, and the resulting contamination clogs and further damages the system until it fails entirely. Regular maintenance, particularly checking and changing transmission fluid according to the manufacturer's recommendations, is key to preventing this chain reaction.
