What is at oil?

AT oil stands for Automatic Transmission Oil. It is a type of hydraulic fluid that is specifically designed for use in automatic transmissions. The main purpose of AT oil is to lubricate the various moving parts within the transmission system, such as gears, clutches, and bearings.

AT oil has a range of important functions in an automatic transmission. It helps to reduce friction and wear on the transmission components, ensuring smoother and more efficient operation. It also assists in transferring power from the engine to the wheels, allowing for seamless gear shifting and acceleration.

In addition to lubrication, AT oil also provides cooling properties. Automatic transmissions generate heat during operation, and the AT oil helps in dissipating this heat to prevent overheating. It is important to maintain the proper level and quality of AT oil to avoid transmission problems and ensure maximum performance and longevity.

AT oil is typically red or pink in color to allow for easy identification and differentiation from other fluids in the vehicle. It is recommended to use the specific type of AT oil recommended by the vehicle manufacturer to ensure compatibility and optimum performance.

Regular maintenance of the AT oil, such as regular checks of the fluid level, replacement at recommended intervals, and addressing any leaks or contamination, is essential for keeping the automatic transmission in good working condition. It is advisable to refer to the vehicle's owner manual or consult a professional mechanic for specific recommendations regarding AT oil maintenance.
