68RFE Transmission

68RFE Transmission Specs & Gear Ratios

 

 

 

 

Chrysler's 68RFE is the company's first diesel specific transmission - unlike previous designs it was engineered specifically to meet the needs and demands of the 6.7L Cummins turbodiesel. The transmission's bandless design and upgraded filtration system significantly extends maintenance intervals and reduces service costs. Additionally, the transmission is significantly stronger than Chrysler's 47RE & 48RE proved to be.
