Ram Cummins Trucks Are Built Tough, But They Still Need the Right Care

The 6.7 Cummins diesel powering current Ram heavy-duty trucks is one of the strongest and most capable diesel engines available in a pickup, but it comes with a more complex emissions system than older Cummins generations and specific maintenance requirements that should not be overlooked. The diesel particulate filter, DEF system, and EGR components all need to be in good working order for the truck to perform correctly and avoid the reduced power modes that leave Ram owners frustrated on the road or the job site. The 68RFE automatic transmission paired with many Ram Cummins trucks has known pressure and torque converter concerns at higher mileage that are worth monitoring in trucks used for regular heavy towing. We know these platforms and we know where to look when something is not right.

Good Questions Deserve Straight Answers.

We have heard just about everything. If you are wondering about it, chances are someone else was too.

What are the most common problems with Ram Cummins diesel trucks?

On the newer 6.7 Cummins trucks, emissions system issues are among the most frequently seen concerns, including diesel particulate filter faults, DEF system problems ranging from contaminated fluid to failed NOx sensors, and EGR system buildup that affects performance and fuel economy over time. The 68RFE automatic transmission is a common topic among Ram owners who tow heavily, with torque converter shudder and pressure-related shifting issues showing up at higher mileage in trucks that work hard. Fuel dilution of the engine oil from DPF regeneration cycles is also worth monitoring on 6.7 trucks that do a lot of short-trip driving, making regular oil condition checks an important part of ownership.

How often does the DEF system need to be serviced on a Ram Cummins?

The DEF system itself does not have a traditional service interval the way the fuel filter or engine oil does, but there are maintenance practices that keep it functioning correctly. Using quality DEF fluid from a reputable source matters since contaminated or degraded DEF can damage the DEF injector and the SCR catalyst. The DEF tank should not be allowed to run dry since doing so will put the truck into a reduced power mode that requires a dealer-level reset in some situations. The DEF injector, NOx sensors, and SCR catalyst can all develop faults over time and mileage, and we diagnose and address those issues correctly when they come up.

Is the Aisin transmission worth it over the 68RFE in a Ram Cummins?

The Aisin AS69RC is widely regarded as the stronger and more reliable transmission option for Ram Cummins trucks that do serious towing or high-mileage work. It has a more robust internal design than the 68RFE and tends to hold up better under the sustained thermal and mechanical stress of regular heavy towing. The 68RFE is adequate for lighter use and can be made more reliable with proper fluid service and some targeted upgrades, but owners who push their Ram hard on a consistent basis tend to prefer the Aisin. If you are considering a Ram purchase and towing performance is a priority, the transmission choice is worth factoring into your decision.
