What kind of transmission fluid does a 2017 Ram 3500 Aisin take?
The 2017 Ram 3500 equipped with the Aisin 68RFE automatic transmission requires Mopar ATF+4 (MS 9602) transmission fluid.
In practical terms, using the recommended ATF+4 fluid is essential for proper shift quality, friction characteristics, and overall transmission longevity. The Aisin 68RFE is a Chrysler/Dodge automatic that relies on the ATF+4 specification; substituting Dexron VI or Mercon variants is not advised and can affect performance and warranty coverage. This article reviews the official specification and offers guidance on compatible options you can buy today.
Official fluid specification and compatible options
Below are the fluid options that meet the OEM specification for the 68RFE. Always verify on the bottle that it explicitly states compatibility with MS 9602 (ATF+4) before purchasing.
- Mopar ATF+4 (MS9602) — the OEM specification for the 68RFE and the safest choice for warranty and reliability.
- Castrol Transmax ATF+4 — a widely available third-party option that meets ATF+4/MS 9602 compatibility claims.
- Valvoline ATF+4 Multi-Vehicle — marketed to meet ATF+4/MS 9602; confirm the label states MS 9602 compatibility.
- Total Quartz ATF+4 — another manufacturer offering ATF+4 that is compatible with the MS 9602 standard; check packaging for the designation.
Choosing any ATF+4 fluid that clearly states MS 9602 compatibility is crucial. Using Dexron VI or Mercon variants can negatively impact shift quality and transmission longevity, and may affect warranty eligibility.
Summary
The 2017 Ram 3500 with the Aisin 68RFE requires ATF+4: Mopar ATF+4 remains the safest choice, with several reputable third-party ATF+4 fluids that explicitly certify MS 9602 compatibility as suitable alternatives. Always read the product label to confirm MS 9602 compatibility, and avoid non-ATF+4 fluids unless specifically approved by Chrysler for this transmission. For any doubt, consult your dealer or the owner’s manual before refilling.
How much transmission fluid does a Ram 3500 Aisin hold?
A Ram 3500 with an Aisin transmission has a drain and refill capacity of about 7.2 quarts (6.8 liters), while a drain and filter change requires 9 to 10 quarts (8.5 to 9.4 liters). The total dry fill capacity is 13.7 quarts (13 liters), though a full flush will use more fluid than a simple refill.
| Service | Capacity |
|---|---|
| Drain and refill | ~7.2 quarts (6.8 liters) |
| Drain, filter change, and refill | 9.0–10.0 quarts (8.5–9.4 liters) |
| Dry fill (total capacity) | 13.7 quarts (13 liters) |

What transmission fluid goes in a Ram 3500?
The Dodge Ram 3500 transmission fluid type varies by year and transmission, but common types are ATF+4 for the 68RFE transmission, Mopar ASRC Automatic Transmission Fluid for the Aisin AS69RC, and ZF Lifeguardfluid8 or Mopar 8 & 9 Speed ATF for the 8-speed transmissions. Always consult your owner's manual or check the vehicle's specific transmission to confirm the correct fluid.
Common transmission types and fluids
- 68RFE: Requires ATF+4.
- Aisin AS69RC: Requires Mopar ASRC Automatic Transmission Fluid (or equivalent like Exxon Mobile 3309).
- 8-speed automatic: Requires a specific fluid like ZF Lifeguardfluid8 or Mopar 8 & 9 Speed ATF (part numbers like 68218925AA, 68218925AB, or 68339073AA).
Important considerations
- Manual transmission: Some older manual transmissions may specify a GL-4 rated gear oil, but always check your owner's manual.
- Fluid type is critical: Using the wrong type of fluid can lead to performance issues and costly damage.
- Confirm your vehicle: The best way to ensure you have the right fluid is to check your owner's manual for the specific transmission in your truck.
What kind of transmission fluid does a 6.7 Cummins take?
The 6.7 Cummins transmission fluid type depends on the transmission installed: for the common 68RFE 6-speed automatic, use ATF+4 fluid. For the less common Aisin AS69RC 6-speed automatic, the correct fluid is the MOPAR ASRC fluid or a fluid that meets the Aisin T-IV / JWS 3309 specification.
For the 68RFE transmission
- Fluid Type: ATF+4.
- Specifications: This is the factory-recommended fluid for all 68RFE and 66RFE transmissions in the 6.7L Cummins.
- Examples: Valvoline ATF+4, Mobil ATF+4, or other brands that meet the ATF+4 specification.
For the Aisin AS69RC transmission
- Fluid Type: MOPAR ASRC Automatic Transmission Fluid or a fluid that meets the Aisin T-IV / JWS 3309 specification.
- Examples: Eurol ATF 1100 or other fluids specifically designed for Aisin transmissions that require the T-IV specification.
Is all ATF +4 full synthetic?
Yes, ATF+4 is a synthetic automatic transmission fluid that is licensed by Fiat Chrysler Automobiles (FCA) to meet specific performance standards for Chrysler, Dodge, and Jeep vehicles. It is engineered to provide better thermal stability, reduced wear, and consistent shifting compared to conventional fluids.
- Composition: ATF+4 is a full-synthetic fluid designed to protect automatic transmissions in FCA (now Stellantis) vehicles.
- Licensing: The "ATF+4" designation is a registered trademark licensed by FCA, ensuring that products from different brands meet the same quality standards.
- Benefits: The synthetic formula offers superior performance over conventional fluids, including better protection against heat, oxidation, and wear, which extends transmission life.
- Usage: It is backward-serviceable, meaning it can be used in older transmissions that require ATF+, ATF+2, or ATF+3 fluids, and it is the standard for many newer models as well.
