What kind of transmission fluid does a 4l60e take?


The 4L60E is a popular automatic transmission used in many vehicles. One common question that arises is, “What kind of transmission fluid does a 4L60E take?” In this article, we will explore the specific type of transmission fluid recommended for the 4L60E and provide additional information about its importance.

The 4L60E transmission is designed to operate with Dexron III or Dexron VI transmission fluid. Dexron III is an older specification, while Dexron VI is a newer and more advanced fluid. Both types of fluid are compatible with the 4L60E transmission, but Dexron VI is the preferred choice due to its improved properties and enhanced performance.

Dexron VI transmission fluid offers better oxidation resistance, improved friction durability, and superior low-temperature fluidity compared to Dexron III. These characteristics contribute to smoother shifting, reduced wear on internal components, and overall improved transmission performance.

It is important to note that using the correct type of transmission fluid is crucial for the longevity and proper functioning of the 4L60E transmission. Using the wrong fluid can lead to various issues, including poor shifting, increased wear, and potential damage to the transmission.

Checking and Changing Transmission Fluid

To ensure the 4L60E transmission operates optimally, it is essential to regularly check and change the transmission fluid. The frequency of fluid changes may vary depending on driving conditions, but it is generally recommended to change the fluid every 30,000 to 60,000 miles.

To check the transmission fluid level, locate the transmission dipstick (usually labeled as “Transmission” or “ATF”) under the hood. With the engine warmed up and running, pull out the dipstick, wipe it clean, reinsert it, and then pull it out again. The fluid level should be within the designated range on the dipstick.

To change the transmission fluid, the vehicle needs to be lifted and supported securely. The transmission pan is then removed to drain the old fluid. It is also advisable to replace the transmission filter during this process. Once the pan is reinstalled, the correct amount of fresh Dexron VI transmission fluid should be added according to the manufacturer’s specifications.


In conclusion, the 4L60E transmission requires Dexron III or Dexron VI transmission fluid. While both types are compatible, Dexron VI is the recommended choice due to its superior performance. Regularly checking and changing the transmission fluid is crucial for maintaining the 4L60E’s optimal performance and longevity.
