What are the consequences of not changing manual transmission fluid?
1 Answers
The impacts of not changing manual transmission fluid are as follows: 1. Reduced oil pressure: This causes the transmission fluid to thicken, lowering oil pressure and hindering internal heat dissipation, leading to excessively high oil temperatures. Consequently, the lifespan of both the transmission and drivetrain components will be shortened. 2. Slippage phenomenon: Failure to change transmission fluid may result in weak acceleration during startup and frequent slippage while driving. 3. Accelerated wear: Prolonged neglect of transmission fluid changes leads to deterioration and evaporation under high-speed and high-temperature conditions, causing rapid component wear and internal transmission damage. Additional impacts include: 1. Impaired vehicle performance: Unchanged transmission fluid affects car performance. During transmission operation, friction between metal components generates debris and impurities. Over time, the fluid becomes contaminated, affecting gear shifts, clogging oil passages, resulting in rough shifting, reduced transmission efficiency, sluggish acceleration, and increased fuel consumption to some extent. Degraded transmission fluid can cause inadequate lubrication, accelerated part wear, and component corrosion, thereby shortening the transmission's service life. 2. Regular inspection required: Transmission fluid should be inspected periodically, typically replaced every approximately 80,000 kilometers. Different transmission designs and performance characteristics require specific viscosity indexes and lubrication properties in transmission fluids. Using incorrect transmission fluid may cause jerky or rough transmission operation during driving.
