Our 66RFE Transmission HD Street is built to handle your toughest towing jobs or moderate performance modifications. This veteran crafted Ram 2500/3500 unit features an updated Freedom Series billet valve body, a high pressure pump, 25% more Overdrive clutch surface area, upgraded snap rings, and up to 67% increase in line pressure. The 66RFE transmission pairs with 5.7 and 6.4 Hemi engines to put in work. It also has mild to moderate performance potential when paired with a custom stall billet converter for customers with custom cam shafts.
