Does it matter what type of ATF you put in your transmission?
As the owner of Kevin's Autos, I often encounter questions about automatic transmission fluid (ATF) and its importance in vehicle maintenance. Many car owners may wonder if it truly matters what type of ATF they use in their transmissions. The answer is a resounding yes! Using the correct type of ATF is crucial for the longevity and performance of your vehicle's transmission. In this article, we will explore why the right ATF matters and how to choose the best one for your car.
Why the Right ATF Matters
Automatic transmission fluid serves several essential functions in your vehicle. Here are some key reasons why using the correct type of ATF is vital:
- Lubrication: ATF lubricates the moving parts within the transmission, reducing friction and wear.
- Cooling: It helps dissipate heat generated during operation, preventing overheating and potential damage.
- Hydraulic Function: ATF provides the necessary hydraulic pressure for the transmission to shift gears smoothly.
- Contaminant Removal: It helps to clean and suspend contaminants, preventing them from causing damage to the transmission components.
Types of ATF
There are various types of ATF available, and each is formulated for specific transmission types. Here are the main categories:
- Dexron: Commonly used in GM vehicles, this fluid has several variations, including Dexron III and Dexron VI.
- Mercon: This is Ford's equivalent, with versions like Mercon V and Mercon LV.
- Multi-Vehicle ATF: Some fluids are designed to work in multiple vehicle makes and models, but it's essential to check compatibility.
- OEM-Specific ATF: Many manufacturers recommend specific fluids for their vehicles, which often provide the best performance.
Choosing the Right ATF
To ensure you select the correct ATF for your vehicle, follow these steps:
- Consult Your Owner's Manual: This is the best source for information on the recommended ATF type for your vehicle.
- Check for Specifications: Look for the fluid specifications, such as Dexron or Mercon, and any specific viscosity ratings.
- Consider OEM Recommendations: If your vehicle is still under warranty, using the manufacturer's recommended fluid can help maintain warranty coverage.
- Seek Professional Advice: If you're unsure, consult a trusted mechanic or auto service professional for guidance.
Conclusion
In summary, using the correct type of ATF in your transmission is essential for maintaining your vehicle's performance and longevity. By understanding the importance of ATF and following the guidelines for selecting the right fluid, you can help ensure your transmission operates smoothly for years to come.

Frequently Asked Questions
Does it really matter what transmission fluid you use?
It is quite important to use a transmission fluid which matches the specification recommended by the manufacturer. There are many specifications, whether it is GM Dexron, Ford Mercon, Honda DW-1, Dual Clutch, CVT transmission fluid, and so on.
Are all ATF transmission fluid the same?
Automatic transmission fluids will have different viscosities, friction coefficients and additives that will impact which types of vehicles they should be used in. The makeup of the transmission fluid protects the transmission and enables improvement in fuel economy.
Can you change ATF without changing the filter?
Keeping that in mind, it's recommended that you change your transmission filter whenever you have to perform a transmission fluid change.
Is ATF the same as DEXRON?
DEXRON is the trade name for a group of technical specifications for automatic transmission fluid (ATF) created by General Motors (GM). The name was first registered as a trademark and later evolved into a brand of GM.
Can I use any kind of transmission fluid?
You have different brands with different mixtures and additives designed for specific types of transmissions. Using the wrong kind of transmission fluid in your car can lead to major damage over time.
Can ATF be used in all automatic transmissions?
Automatic transmission fluid (ATF) is used in all cars that have automatic transmissions and in certain modern manual transmission cars.
What is the best transmission fluid?
Recommended Products. Valvoline Dexron VI/Mercon LV ATF is the full-synthetic automatic transmission fluid that has been uniquely engineered to meet and exceed the requirements of the General Motors Dexron VI specification and is officially licensed and approved by GM.
Why do mechanics say not to change transmission fluid?
That bad fluid may have a “sticky” quality to it or metal flecks that act to aid friction, and if it's changed, the new fluid might cause the transmission to start slipping.
Is it OK to mix different types of ATF?
Mixing different transmission fluids is generally not recommended. Here are some key reasons why: Compatibility Issues: Different transmission fluids are formulated with specific additives and base oils. Mixing them can lead to chemical reactions that may degrade the performance of the fluid.
What happens if you use the wrong ATF fluid?
Using the wrong fluid can result in poor lubrication, increased wear, and even damage to internal components. Overheating: Non-recommended fluids may not have the proper thermal stability, which can cause the transmission to overheat. This can lead to premature failure.
