Best Atf+4 Transmission Fluid

ATF+4 is an automatic transmission fluid used in most Chrysler vehicles manufactured since 1996. It’s specifically designed to handle the complicated requirements of a modern electronically controlled transmission, providing superior lubrication and preventing wear on parts. ATF+4 also prevents corrosion and helps reduce foaming which can lead to power loss or even failure of your vehicle’s transmission system.

When choosing ATF+4, it’s important to use only genuine Mopar® brand fluid as generic fluids may not provide the same protection level or performance benefits. Regular maintenance with ATF+4 will help keep your vehicle running smoothly for years to come!

Atf+4 transmission fluid is one of the best fluids you can use for your vehicle. It’s designed to protect against wear and tear, provide smooth shifting, reduce heat buildup and improve fuel efficiency. Plus, due to its superior thermal stability properties it won’t break down or become contaminated as quickly as other types of automatic transmission fluids.

This all adds up to a longer lasting and more reliable drivetrain that will help keep your car running smoothly over time.

The Best Automatic Transmission Fluid for Your Car (Synthetic)

Are All Atf 4 Transmission Fluids the Same?

No, not all ATF 4 transmission fluids are the same. Each type of fluid has different levels of viscosity and additives that can be used to better suit a specific vehicle’s needs. OEMs often require their own proprietary formulations for use in their transmissions, meaning that even though two vehicles might both need ATF 4 fluid, they may require different blends in order to perform optimally.

Generally speaking, however, most ATF 4 fluids will offer protection against wear and tear on engine components as well as provide lubrication and cooling needed for optimal performance.

Is Atf+4 Always Synthetic?

No, ATF+4 is not always synthetic. The term “ATF+4” refers to a type of automatic transmission fluid (ATF) that meets the service requirements set by Chrysler for use in their 45RFE and 545RFE transmissions. However, this does not necessarily mean that it must be synthetic oil.

Although many manufacturers have chosen to develop fully-synthetic ATF+4 formulations, there are some conventional mineral oil-based fluids available on the market as well which meet these requirements and can be used as an alternative option.

What Transmission Fluid is Compatible With Mopar Atf 4?

Mopar ATF 4 is a multi-vehicle, fully synthetic automatic transmission fluid that can be used in most vehicles manufactured by Chrysler. It’s compatible with many types of transmission fluids including Dexron/Mercon, Mercon V and DEXRON-VI as well as other OEM specified fluids. Additionally, it meets or exceeds the performance requirements for all Mopar ATF+4 transmissions.

Mopar ATF 4 provides optimal protection against wear, corrosion and oxidation while also providing excellent lubrication characteristics over a wide range of operating temperatures.

Is Atf 4 the Same As Dexron 4?

No, ATF 4 is not the same as Dexron 4. ATF 4 is a transmission fluid developed by General Motors specifically for use in their automatic transmissions and power steering systems. It is a synthetic blend of hydrocarbons and esters designed to improve wear protection, oxidation stability, corrosion resistance, foaming control and viscosity at high temperatures.

On the other hand, Dexron 4 is an automotive lubricant produced by Chevron Corporation that meets GM’s specifications for its Automatic Transmission Fluid (ATF). Although it provides many of the same benefits as ATF 4 such as improved wear protection and better oxidation resistance compared to Dexron 3 fluids, it does not offer superior performance in terms of increased fuel efficiency or reduced noise levels like its predecessor.

Atf+4 Transmission Fluid Equivalent

Atf+4 Transmission Fluid Equivalent is a synthetic, multi-grade transmission fluid that meets or exceeds the requirements of Chrysler ATF+4 and many other North American and Asian manufacturers. It provides superior protection in modern high performance transmissions, ensures smooth shifting over a wide temperature range, offers improved oxidation stability for longer life expectancy and protects against rust, corrosion and sludge deposits.

Mopar Atf+4 Automatic Transmission Fluid

Mopar ATF+4 Automatic Transmission Fluid is a high-performance, synthetic transmission fluid designed to meet the rigorous demands of today’s advanced transmissions. It provides superior lubrication and protection for extended service intervals in most Chrysler, Dodge, Jeep and other vehicles equipped with automatic transmissions built since 2005. Mopar ATF+4 offers improved oxidation resistance that helps protect against viscosity breakdown due to thermal breakdown at higher temperatures while maintaining excellent low temperature properties for smoother shifting during cold weather starts.

Atf+4 Transmission Fluid 5 Gallon

ATF+4 Transmission Fluid is a high performance, synthetic blend automatic transmission fluid designed to meet the demanding requirements of modern passenger vehicles. It provides superior lubrication and protection for transmissions and offers improved oxidation stability, excellent thermal stability, anti-shudder performance, and wear protection. The 5 gallon size is ideal for use in larger vehicles such as buses or fleet vehicles with higher transmission capacities.


Overall, ATF+4 transmission fluid is the best fluid to use in Chrysler vehicles. It provides superior performance and ensures long-term reliability of your transmission system. It also helps keep your car running smoothly and efficiently for a longer period of time, making it an excellent choice for anyone who wants to protect their vehicle from wear and tear.

With its wide range of benefits, there’s no doubt that ATF+4 transmission fluid is one of the top choices when it comes to keeping your car running like new.
