Fluid type explained
The 2015 Ram 3500 equipped with the Aisin AS69RC heavy-duty automatic transmission requires Mopar ATF+4 transmission fluid. It is crucial to use a fluid that explicitly meets or exceeds the ATF+4 specification. This is a synthetic-based fluid designed for superior performance and protection in demanding applications. Using an incorrect fluid type, such as Dexron, Mercon, or universal ATFs not meeting ATF+4, can lead to premature wear, poor shift quality, overheating, and ultimately, transmission failure. The AS69RC is a robust unit, but it relies on the correct fluid's specific frictional properties, viscosity, and additive package to operate as designed, especially under the heavy loads that a Ram 3500 is built to handle.
While Mopar ATF+4 is the OEM recommendation, several reputable aftermarket brands produce fluids that are officially licensed or state they meet the ATF+4 specification. Always look for this specific designation on the product label. Beware of
