Transmission oil is a fundamental element in the maintenance of any vehicle, as it ensures the correct operation of the transmission system. This component not only ensures efficient operation, but also prolongs the life of the system, preventing mechanical failures and costly repairs.
In this article, we will explore what transmission oil is, its main functions and the importance of its maintenance.
What is transmission oil
Composition and types of transmission oil
Transmission oil is a lubricant designed to reduce friction between the internal components of the transmission system, as well as to dissipate the heat generated by its operation. This oil can be composed of mineral or synthetic bases and is classified into two main types:
- Manual. Designed for manual gearboxes, it provides a viscosity level that facilitates gear shifting and reduces gear wear.
- Automatic (ATF). Formulated for automatic transmissions, it includes special additives to improve power transfer and maintain proper temperature.
Differences between transmission oil and other vehicle lubricants
Unlike engine oil, which focuses on protecting the engine from internal combustion, oil for transmission is designed specifically for the components of the shifting system. This means that its viscosity, heat resistance and additive properties are unique to this application.
At American Petroleum, we offer a wide range of high quality oil for transmissions. See our available options in our section of lubricants in Puerto Rico.
Main functions of transmission oil
These are the 3 main functions of oil for transmission:
Lubrication of internal components.
Transmission oil reduces friction between gears and other metal components within the system, minimizing wear and prolonging the life of the vehicle.
Heat reduction and overheating prevention
During operation, the transmission generates heat due to friction and power transfer. The oil acts as a medium to dissipate this heat, preventing overheating and possible internal damage.
Power transfer and improved vehicle performance
In automatic transmissions, oil helps transfer power from the engine to the wheels smoothly and efficiently, improving performance and the driving experience.
Frequently asked questions about transmission oil
- How do I know when to use oil for transmission?
Oil for tranmission should be changed when it exhibits changes in color and viscosity, such as a dark color or thick texture. Other indicators include unusual odors, presence of metallic particles, difficulty shifting gears or strange noises during operation.
- What happens if you don’t maintain transmission oil properly?
Poor oil maintenance can cause premature wear of transmission components, increasing repair costs and the risk of serious mechanical failure. More details on how to avoid these problems are available in our guide on automatic transmission maintenance.
- How to check and change transmission oil
To check the oil level and quality, refer to the vehicle manual and use the transmission dipstick. Change the oil according to the manufacturer’s recommendations, generally between 30,000 and 60,000 miles (or 50,000 to 100,000 kms). It is important to use professionals to ensure proper maintenance. Get complete information on our transmission oil change page.
- What transmission oil is best for tractors?
Tractors require universal oils for transmission designed to withstand high loads and demanding conditions. Discover our recommendations in our section dedicated to transmission oil for tractors.
- Which oil is best for an Allison transmission?
For Allison transmissions, we recommend oils specifically formulated to meet your performance requirements. See our available options for this type of transmission in our specialized guide.
