The 68RFE transmission was released by Chrysler in mid 2007. Specifically designed for 2500 and 3500 Dodge Ram diesel trucks, the 68RFE was designed to handle the increased torque of diesel engines with modified internal components and a larger bell housing compared to that of it's 48RE and 545RE predecessors. The overdrive is a common 68RFE failure point. Benton's Diesel & Transmission offers 5 upgraded fully built 68RFE transmission solutions to meet the demands and applications of our customers. We build 68RFE transmissions with towing upgrades all the way to 1000+ horsepower units for racing.
