About this part

Product Details

The aFe POWER ShiftLogic Transmission Module greatly improves transmission shift feel in the 2005-2007 Dodge RAM 2500/3500 L6-5.9L (td) Cummins with the 48RE transmission. The 48RE transmission is known for its shudder and slippage at low RPM, especially when power adders are used. The aFe POWER ShiftLogic Transmission Module modifies the transmission line pressure, resulting in improved shift firmness and reduced transmission slippage while also reducing fluid temperature and extending the life of your transmission. The aFe POWER ShiftLogic Transmission Module has three different settings (Stock, Stage 1, Stage 2) to personalize your shift feel. The adjustment can easily be done with a simple push of the button on the module. LED Setting Options: No LED - Stock Setting/Orange LED - Stage 1 Setting/Red LED - Stage 2 Setting. The aFe POWER ShiftLogic Transmission Module is plug and play. By utilizing OE factory-style connectors, the harness connects directly to the factory connector on the transmission. No cutting or splicing of wires is necessary, making installation extremely easy. The aFe POWER ShiftLogic Transmission Module works in combination with other aFe POWER performance products and is ideal for street performance and towing applications
