Using the right amount of transmission fluid can help protect your Toyota Corolla. The 2011 Toyota Corolla has an automatic transmission and requires a specific fluid type.
The automatic transmission fluid in a Toyota Corolla can last up to 100,000 miles but it’s important to change it every 20,000 miles. It’s also important to check the fluid level between changes.

1. ATF WS
Designed specifically for modern Aisin-Warner automatic transmissions, the ATF WS is a low-viscosity synthetic, low friction formulation. It offers full protection for all parts and reliable performance under high loads.
The ATF WS provides excellent shear stability, seal compatibility, and oxidation resistance. It also helps reduce fuel consumption and extends the service life of automatic transmissions in high load situations.
This synthetic low viscosity fluid is formulated for Toyota and Lexus vehicles equipped with AISIN-WARNER automatic transmissions. It offers a lower viscosity than previous Toyota specifications requirements, constituting less than 6 cSt in operating condition, to reduce inner resistance losses and fuel consumption.
2. ATF GL-4
ATF GL-4 is a multi-vehicle gear oil that was specifically designed for vehicles where the manufacturer specifies a GL-4 lubricant. It provides outstanding protection and lubrication of the transmission and transaxles of passenger cars, service and other vehicles over a wide range of climatic conditions and temperatures.
A synthetic automatic transmission fluid that performs superior shiftability and thermal stability at cold temperatures compared to petroleum ATFs. It also prevents varnishing of valves and clutches, which can lead to transmission failure.
GL-4 lubricants are also recommended for spiral bevel and hypoid differentials, power dividers, and oil-lubricated steering axle wheel bearings. These oils have been qualified under U.S. Military specifications MIL-L-2105D (formerly MIL-L-2015C) and MIL-PRF-2105E, and SAE J2360.

3. ATF GL-5
The capacity of a transmission fluid can vary based on the manufacturer. This is why it’s important to check your vehicle’s owner’s manual to determine which type of fluid you need.
Generally, automatic transmission fluid is recommended for all-wheel drive vehicles and other vehicles with high-powered engines, while manual transmission fluid is more common in light vehicles. The right transmission fluid will help you keep your car running smoothly and last longer.
The ATF GL-5 is one of the best synthetic automatic transmission fluids you can buy. It’s engineered to increase viscosity, friction resistance, and foam control for easier shifting and improved transmission life.
4. ATF GL-6
The ATF GL-6 is an excellent choice for most manual transmissions. It’s a high-performance ATF that delivers superior wear protection and oxidation stability. It’s also formulated with additives that help prevent rust and corrosion.
GL ratings are the American Petroleum Institute’s way of classifying gear oil, with lower GL ratings for use in gearboxes and higher GL ratings for use in separate differentials (where fitted). The higher the GL rating, the better the lubricant performs in terms of reducing frictional wear.
This product is suitable for Dexron, Dexron III, Dexron-III H, IIE, and II transmissions, as well as all Mercon transmissions. It’s one of the best automatic transmission fluids available, and it comes in a huge bottle, meaning you won’t have to refill your vehicle too often.

5. ATF GL-7
Automatic transmission fluid (ATF) is designed to last up to 100,000 miles. But even normal driving can raise ATF temperatures beyond safe limits, diminishing its life.
Fortunately, there are some ways to extend the lifespan of ATF:
First, use an auxiliary transmission cooler that will bring temperatures down to a more reasonable range. These coolers are available from a variety of manufacturers, and many shops install them as part of a full transmission flush.
Second, change the ATF filter regularly. This will remove sludge and dirt from the fluid that can reduce its effectiveness. Finally, be sure to check the fluid level periodically and add it as needed until the dipstick shows full.
