FCA ATF+4® Licensing Program

Frequently Asked Questions

The use of “synthetic” in ATF+4® is not a definitive “yes” or “no” question. First it is important to understand how the term “synthetic” may be used. Advanced technologies in lubricant refining, such as hydrocracking, have made it possible to refine mineral oils to such a point that the mineral oils are technically regarded as synthetic oils and may legally be marketed as such. Therefore, lubricant marketers may use the term “synthetic”, “partially synthetic”, “synthetic blend”, “fully synthetic”, or some other terminology, when the base lubricant is derived from 100% synthetic materials, 100% highly refined mineral oil, or any combination thereof. So “synthetic” is really more of a marketing term than a statement of whether the base oil comes from man-made materials or mineral oil.

No, only licensed ATF+4® products (with "ATF+4®" as part of the brand name and a valid license number on the back of the label) contain the unique formulation. Other look-alike products that claim to be suitable for use in FCA or Chrysler transmissions have not gone through FCA’s rigorous testing process, are not monitored for quality, and are not approved or recommended for use in FCA transmissions.

ATF+4® is a unique formulation that has been designed specifically to meet the exacting requirements of FCA transmissions. The fluid has gone through an extensive developmental and testing process, including more than one million miles of severe field testing. It is a high performance fluid that provides significant reduction in component wear, superior temperature performance, consistent shift quality, and exceptional friction modifying properties.

Yes, as long as it is FCA licensed and approved ATF+4® (with "ATF+4®" as part of the brand name) and a valid license number is shown on the back of the label.

Yes, ATF+4® is backwards compatible to ATF+, ATF+2, ATF+3 and MS7176.

To ensure you have removed most or all of the existing ATF, it is recommended that you perform a total of three (3) changes using ATF+4®. It is further recommended that you do not mix ATF+4® with another automatic transmission fluid (ATF).

No. Using an ATF conditioner is not recommended. If you have added a product to your ATF+4®, it is recommended that you drain the existing fluid and replace it with ATF+4®.

Yes, but please note that due to advances in transmission design, modern transmission fluids, including ATF+4®, contain detergents that are designed to clean seals and sediment that has built around them. If this is the first time switching your automatic transmission fluid it is recommended that you watch for leaks, or change your seals as a preventative measure.

No. Please consult your owner’s manual for the correct ATF or MOPAR ATF that is specifically designed for your vehicle.
