Mopar ATF+4

Mopar ATF+4 automatic transmission fluid is the OEM product of Fiat Chrysler Automobiles (formerly Chrysler Group) for a wide range of automatic transmissions in vehicles of the group brands Chrysler, Jeep, Dodge and RAM. Mopar ATF+4 is characterized by its high-quality base oils combined with a very high viscosity index (VHVI) and a unique additive package. If you are a user or vehicle owner and attach importance to using Mopar products for your vehicle, then Mopar ATF+4 is exactly the right automatic transmission fluid for your vehicle!

Broad application spectrum also beside the automatic transmission

Mopar ATF +4 automatic transmission fluid is designed to provide "fill for life" automatic transmission lubrication under normal driving conditions.
In addition to automatic transmissions, ATF +4 automatic transmission fluid is also used in many manual transmissions, power steering systems (post 1998) and differentials. To use the appropriate lubricant, please always refer to your vehicle manual or contact us. Our technical support staff will be happy to help you!

Suitable for many Chrysler, Jeep, Dodge vehicles - with exceptions!

Among many other vehicle models, Mopar ATF+4 is also used in 4- to 6-speed automatic transmissions, as well as older 3-speed converter transmissions of Chrysler models:

• Chrysler (Grand) Voyager
• Chrysler 300
• Chrysler PT Cruiser
• Chrysler Sebring

In addition to a large number of Dodge vehicles of the models:

• Dodge Caliber
• Dodge Journey
• Dodge Nitro
• Dodge Avenger
• Dodge Challenger
• Dodge Charger
• Dodge Magnum
• Dodge RAM

also need vehicles of Jeep models:

• Jeep Cherokee
• Jeep Grand Cherokee
• Jeep Commander
• Jeep Compass
• Jeep Wrangler

an ATF+4 transmission fluid.

When selecting the correct automatic transmission oil, please be sure to follow the instructions in your vehicle manual. Especially in a large number of newer vehicles of the mentioned models other automatic transmissions are installed, in which no ATF+4 automatic transmission oil may be used!

Backwards compatible with ATF+, ATF+2 and ATF+3

Mopar ATF+4 is the successor to the previous products ATF+, ATF+2 and ATF+3, which are no longer available as OEM products, as ATF +4 automatic transmission fluid is fully backwards compatible.
Development work by major automakers on automatic transmission fluid picked up steadily in the 1980s after initial efforts that can be traced back to the 1940s. In addition to products from Ford, GM and Toyota, Chrysler introduced "ATF+" automatic transmission fluid with the Chrysler MS-7176 specification. In line with the rapid technical development, the "ATF+" was quickly followed by the Chrysler MS-7176D and Chrysler MS-7176E specifications in 1993 and 1997, which were introduced as "ATF+2" and "ATF+3" automatic transmission oils. Significant for these two further developments of the original ATF+ was the improvement of the shear stability of these oils, i.e. the minimization of viscosity loss with increasing thermal load.
SAE Technical Paper 982674 gives the following shear losses from a 20-hour KRL shear test:

• Chrysler MS-7176D ATF+2: 32%
• Chrysler MS-7176E ATF+3: 14%

For immediate comparison, the test also cites results on the comparable GM Dexron III and Ford Mercon V specifications:

• GM Dexron III: 40%
• Ford Mercon V: 19%

The immense improvement in shear stability from ATF+2 to ATF+3 can be attributed to the use of the then new Group II base oil (for more details on the various base oil classes, see our blog article on automatic transmission oil), as well as the shear-stable viscosity index improver (VI improver for short) developed by Lubrizol.
Once again, an improvement was achieved by the ATF+4 oil with the Chrysler MS-9602 specification, which was factory-filled in automatic transmissions from 1998 onwards. By using a Texaco Group III base oil and another improved viscosity index improver from Lubrizol Corporation, the ATF+4 automatic transmission oil has a shear loss of only 10%.
In addition to the renewed improvement in shear stability, the focus in the development of the ATF+4 fluid was also on improving the ATF+3 automatic transmission fluid in terms of its longevity. In particular, the anti-shudder test cited in SAE Technical Paper 982674, which examines the behavior of an automatic transmission fluid as a function of mileage in terms of its potential to cause judder during transmission operation, shows significant improvements here: While an ATF+3 automatic transmission oil shows noticeable transmission judder after a mileage of 30,000 miles, an ATF+4 oil reaches the same value only after a mileage of 100,000 miles.

How much ATF+4 does your vehicle need?

This question cannot be answered in general. The required fill quantities vary depending on the transmission and vehicle. Our customers therefore purchase quantities between 5 and 10 L for a complete change of their automatic transmission oil. To find out how much automatic transmission oil is required for your vehicle, we recommend that you consult the vehicle manual.
