In the constantly changing world of powertrain engineering, the 68RFE transmission does more than just show up; it makes an impression, leaving a lasting echo rather than a passing whisper in the sacred halls of diesel torque mastery. When Chrysler debuted this gearbox in 2007, it was a completely new design that was painstakingly made to control the powerful output of the 6.7L Cummins turbodiesel engine rather than a modification of an existing unit. It became more than just a luxury to have a gearbox that could achieve that elusive balance as torque figures soared into the 800 lb-ft range and customer expectations expected both mechanical refinement and sheer strength.
