The Mopar ATF+4 equivalents above meet the quality standards and are fit for use. They meet and even surpass quality standards set by various car manufacturers. However, if your vehicle is still under warranty, you should stick with OEM products. Otherwise, dealers may void it when they discover any deviation from the recommended ATF.

Mopar ATF+4 is an ultra-premium OEM full synthetic fluid. They manufacture it for use as factory fill for automatic vehicles under Chrysler Corporation part number 68218057AB. It is backward compatible, hence, can be used for service in transmission models where ATF+, ATF+2, and ATF+3 are recommended. However, if a vehicle is originally filled with ATF+4, you should not use any other fluid. 

The manufacturing process of Mopar ATF+4 considers the enhanced transmission system needs and meets all of them. The extra additives further maximize performance through proper lubrication, protection against wear, corrosion, oxidation, and deposits. Also, the fluid is stable in extreme conditions. It prevents oxidation under heat and operates well under low temperatures.


  • Extends and improves the life of automatic transmissions
  • Prevents oxidation under heat and operates well under low temperatures
  • Proper lubrication of gears for smooth operation
  • Prevents rust, corrosion, and deposits
  • Has improved anti-wear properties
  • Reduces friction


  • It is not possible to tell the condition of the fluid from its color as it changes within a short time

Valvoline ATF+4

Valvoline ATF +4 Full Synthetic Automatic Transmission Fluid is a high-quality product formulated to meet the demands of the Chrysler automatic transmissions. You can use it as a Mopar ATF+4 equivalent. Additionally, it is fully back-serviceable. Therefore, this makes it suitable for applications that need ATF+, ATF+2, ATF+3, and ATF+4. 

The advanced technology used in its manufacture enhances its capabilities, such as anti-shudder protection, thermal stability, improved anti-oxidants, and anti-wear abilities. These features come in handy for any motor vehicle for a smooth ride and a longer-lasting transmission system.


  • Ensures maximum power transfer by the anti-shudder protection
  • Anti-wear technology guarantees you durability
  • Easy flow in cold temperatures ensures lubrication throughout
  • Resistance to breaking down in high temperature prevents corrosion and oxidation


  • Not compatible with some older transmission models

Castrol 6810 Transmax ATF+4 is a fully synthetic, high-quality formulation. Chrysler certifies it for cars and trucks. Because of the high-quality production, Fiat Chrysler has also licensed it for their vehicles. If you need an equivalent or alternative ATF for transmission systems that use Mopar ATF+3, ATF+4, ATF+2, or ATF+, this fluid will serve you well. 

Some features that qualify this fluid as a Mopar ATF+4 equivalent are its superior transmission life, thermal stability, anti-wear, anti-oxidants. Great use of technology in its manufacture coupled with added additives to produce an ATF that can handle the different problem areas that mainly bring challenges in the transmission system. 


  • Gives you smooth transmission, thanks to the anti-shudder additives
  • Constant lubrication in cold temperatures
  • Protection from oxidation, corrosion, and rust for a longer-lasting system
  • Easily accessible


  • Packaging is not entirely leak-proof

What is ATF+4

Most Chrysler cars and trucks use ATF+4 or ATF+3. ATF+4 is an automatic transmission fluid that is fully synthetic with improvements to meet the current transmission system needs. There is the use of different additives to enhance the properties of the fluid, such as its viscosity, chemical reactions, and stability. For quality assurance, Chrysler certifies and gives licenses for ATF that are suitable for their automatic transmissions. ATF+4 can be used in systems that use Dexron and Mercon fluids.


1. Can I use Dexron 3 instead of ATF+4

No. You can only use ATF+4.  

While both are transmission fluids, they contain different additives. For Dexron III, they use crude oil as a base and contains impurities. As a result, the quality is inferior, which affects the transmission systems’ level of performance. Also, it is prone to breaking down on heat, forming sludge and deposits that are detrimental to your transmission system. 

Chrysler automatics are fine-tuned and sensitive hence need high-quality products. ATF+4 fluids are fully synthetic. The extra additives meet the needs of the new transmission systems; without compromising on the overall performance of the vehicle.

2. Can I use ATF 3 instead of ATF 4?

No, you can not. Automobiles that were factory filled with ATF+4 can only have that or its equivalent. Therefore, you cannot use ATF+3 instead of ATF+4. However, ATF+4 is fully back-serviceable, thus can replace the ATF+3. If anything, the manufacture of ATF+3 and below ceased. The remaining stock is currently being faced out of the market.

3. Can I mix different ATF?

You should not mix different ATF.

Mixing different fluids will lower the performance of your transmission system. Various chemicals and additives may react or fail to mix well for the performance you desire.

Unless you are out of options, it is wise to avoid mixing different ATF.

Final Thoughts

The motor industry is growing exponentially. There are new inventions now and then. The continuous improvement of the transmission system presents the opportunity to have an equal speed in ATF production to meet the emerging needs.

OEM fluids remain the best for any vehicle. However, I cannot ignore the fact that at one time, you may need to get an alternative. This could be because of inaccessibility, shortage of fluids, or prohibitive costs. Mopar ATF+4 equivalents come in handy in such instances.

I would recommend any of them. If you want to try a cheaper alternative, then you can go for Valvoline ATF+4. But Castrol Transmax ATF+4 would be my best pick. The product features all those things that can meet your Chrysler specs.
