The 68RFE is a diesel specific transmission, unlike previous designs, engineered specifically to meet the needs of the 6.7L Cummins turbo diesel. The transmission's bandless design and upgraded filtration system extend maintenance intervals and reduce service costs. Additionally, the transmission is significantly stronger than Chrysler's 47RE & 48RE proved to be. Finally, the inline 6 Cummins has a 6 speed transmission to utilize all the engine's torque.
