In fact, these liquids may turn darker after a period of use because they now contain some of the other molecules in the engine. When – the reason is that the oil cleans the engine of sludge and deposits created by high-temperature combustion, keeping these molecules in the oil to prevent them from accumulating on the surface of the machine.

The dark color of the used fluid is caused by deposits of abrasive particles in the engine, smoke, and viscous residue after the oil is heated. After a while, they also age in the machine.

Therefore, based on the color of the transmission fluid, you can determine the quality of the oil and the condition of your car’s Transmission. Some of the primary colors of this liquid are:
