On the 2007-2018 RAM 3500 6.7L Cummins, the 2007-2018 RAM 3500 with the 68RFE 6-speed automatic transmission suffers from premature failure when towing heavy loads (over 10,000 lbs). The 68RFE is a derivative of the older 545RFE and was not adequately engineered for the torque output of the 6.7L Cummins. The overdrive clutch pack, solenoid pack, and torque converter are the primary failure points. Overheating during sustained towing destroys the clutch packs and warps the valve body. Many trucks experience complete transmission failure between 80,000-150,000 miles if used for regular towing. Rebuild cost: $3,000-5,000. Built/upgraded transmission: $5,000-8,000.
For minor issues: Complete fluid and filter change with Mopar ATF+4 (68218057AA) and solenoid pack replacement ($400-800). For overheating prevention: Install an auxiliary transmission cooler and keep temps under 220F. For rebuilds: Use a reputable heavy-duty builder (SunCoast, Randys Worldwide, BD Diesel). A properly built 68RFE with billet shafts, upgraded clutch packs, and triple-disc torque converter ($5,000-8,000) will handle 800+ lb-ft of torque. For 2019+ trucks, the Aisin AS69RC replaced the 68RFE.
