Your 68RFE Cummins is a great jack-of-all-trades transmission that might need tuning to get the most out of it while helping it last longer.
The Chrysler LLC Cummins 68RFE is a six-speed automatic transmission engineered primarily to power the group’s SUVs and heavy-duty trucks. It was first introduced for the Dodge RAM series in 2007, and has since undergone many upgrades, all of which were intended to make the transmission more durable and smoother. Even so, the 68RFE is not perfect, and many owners believe that tuning is the best way to maximize its potential.
The 68RFE took on a difficult task of being a jack of all trades, handling the immense power and torque of a 6.7-liter Cummins, offering extreme towing capabilities, but also being efficient and meeting stringent emissions standards. The main reasons why it may be worth TCM tuning your 68RFE Cummins include reducing slippage, improving heat management, enhancing the clutch lockup system, and increasing power handling and line pressure. Some owners also believe the 68RFE is a weak link in the truck, and because of that, a large aftermarket scene was born to offer tuning solutions for the transmission control module (TCM) intended to make the 68RFE as reliable as it can be.Benefits of 68RFE tuning
