Definition of Transmission Fluid
Transmission fluid is a lubricant that is used in automatic and manual transmission systems. It is typically made up of base oils and additives that help to reduce friction between the moving parts of the transmission system. The fluid also helps to cool and clean the transmission system, as well as provide hydraulic pressure for shifting gears.
Types of Transmission Fluid
There are two main types of transmission fluid: automatic transmission fluid (ATF) and manual transmission fluid (MTF). ATF is designed specifically for use in automatic transmissions, while MTF is used in manual transmissions. Additionally, there are different types of ATF and MTF based on their viscosity ratings and other properties.
Functions of Transmission Fluid
The primary function of transmission fluid is to lubricate the moving parts of the transmission system. This reduces friction between these parts, which can cause wear and tear over time. Additionally, the fluid helps to cool the system by dissipating heat generated by friction. Transmission fluid also provides hydraulic pressure for shifting gears in an automatic transmission system.
In summary, understanding what transmission fluid is, its types, and functions can help you maintain your vehicle’s transmission system properly. Regularly checking your car’s owner’s manual or consulting with a professional mechanic can help you determine which type of transmission fluid your vehicle requires.

Factors Affecting Color Change
Transmission fluid is an essential component of your vehicle’s transmission system. It lubricates the moving parts, cools the system, and helps transmit power from the engine to the wheels. However, over time, the color of your transmission fluid may change, indicating potential problems with your transmission system. Several factors can affect the color of your car’s transmission fluid.
Age and mileage of the vehicle
One of the primary factors that can affect the color of your car’s transmission fluid is its age and mileage. As a vehicle ages, its transmission system undergoes wear and tear, which can cause debris and metal shavings to accumulate in the fluid. This contamination can cause the fluid to darken or turn brown.
Contamination by dirt, debris, or metal shavings
Another factor that can affect the color of your car’s transmission fluid is contamination by dirt, debris or metal shavings. These contaminants can enter into the transmission system through leaks or damaged seals and mix with the fluid. As a result, it may turn black or dark gray.
Overheating of the transmission system
Overheating is another factor that can cause a change in color of your car’s transmission fluid. When a transmission system overheats, it causes damage to internal components such as seals and gaskets which leads to contamination by burnt particles from these components mixing with fluids causing it to appear milky or foamy. It is important to note that if you notice any changes in color in your car’s transmission fluid, you should have it checked immediately by a professional mechanic as this could be an indication of serious problems with your vehicle’s transmission system.
Regular maintenance such as changing fluids at recommended intervals will help prevent issues arising due to these factors affecting colour change in your car’s transmission fluids.
Please note: – Some manufacturers use dye to give their transmission fluid a specific color for easy identification. For example, Chrysler uses a reddish-orange color for their ATF+4 fluid.
