What are the symptoms of insufficient transmission fluid?

[DelNora]

Symptoms of insufficient transmission fluid include: difficulty engaging gears and increased transmission noise. During transmission operation, the meshing and transmission between gears generate significant heat and metal debris from wear. Without the cleaning and cooling effects of lubricating oil, friction between gears increases, leading to noise and shifting difficulties. Prolonged lack of oil can cause severe gear wear and even render the transmission unusable. Transmission fluid must be replaced regularly. If not changed for an extended period, the fluid becomes increasingly viscous, impairing heat dissipation and causing excessive temperatures. Over time, this can affect the transmission's lifespan.
