68RFE Transmission Stage 1

2007.5+ Ram 2500/3500 68RFE
550 Horsepower

The 68RFE Transmission Stage 1 unit was designed for trucks that have a hot tune and like to party on weeknds. The main upgrade in this unit is the converter and the billet channel plate to fix the notorious cross leaks of the 68RFE transmission unit. An optional billet input shaft can be added to this unit to help with heavy towing, or 4WD launches as the OE input shaft is a weak link.

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.
